This particularly applies to modification or replacement of:● Antennas● Antenna cables● readers●Power supply units with connection cables 2.3 Safety distance to transmitter antenna2.3.1 Safety distance between transmitter antenna and personnelFor antenna configurations where it is possible to be briefly or constantly within the transmission range of the antennas, as in loading ramps, for example, minimum distances must be maintained. LimitsThe ICRP (International Commission of Radiological Protection) has worked out limit values for human exposure to HF fields that are also recommended by the ICNIRP (International Commission of Non Ionizing Radiological Protection). In German legislation on emissions (since 1997), the following limit values apply. These can vary according to frequency:Frequency f [MHz] Electrical field strength E [V/m] Magnetic field strength H [A/m]10 - 400 27,5 0,073400 - 2.000 1.375 x f1/2 0.0037 x f1/22.000 - 300.000 61 0,16 The limit values for the 900 MHz reader antenna alternating field are thus:Electrical field strength: E = 41.25 V/mMagnetic field strength: H = 0.111 A/mHF power density: E x H = 4.57 W/m2Safety Information2.3 Safety distance to transmitter antennaSIMATIC RF600System Manual, 06/2010, J31069-D0171-U001-A10-7618 17 Draft Version 02.06.2010
2.3.2 Minimum distance to antenna in accordance with ETSIMinimum distance to antenna in accordance with ETSI (EU, EFTA, Turkey)At a transmission frequency of 900 MHz, the wavelength of the electromagnetic wave λ is approximately 0.34 m. For distances less than 1 λ in the near field, the electrical field strength diminishes exponentially to the power three over distance, and for distances greater than 1 λ, it diminishes exponentially to the power two over distance. The horizontal line at 41.25V/m marks the "safety limit value".For the maximum permisisble transmission power in accordance with ETSI (2W ERP), the "safety distance" d = 0.24 m. This means that personnel should not remain closer than 24cm to the transmitter antenna for extended periods (more than several hours without interruption). Remaining within the vicinity of the antenna for a brief period, even for repeated periods (at a distance < 0.24 m), is harmless according to current knowledge. Distance to transmitter antenna [m] Feld strength [V/m] % of limit value110 245 2 5If the transmitter power is set lower than the highest permissible value (2 watts ERP), the "safety distance" reduces correspondingly.The values for this are as follows:Radiated power ERP [W] Safety distance to transmitter antenna [m]2,0 0,241,0 0,170,5 0,12 Safety Information2.3 Safety distance to transmitter antennaSIMATIC RF60018 System Manual, 06/2010, J31069-D0171-U001-A10-7618 Draft Version 02.06.2010
NoteReduced maximum radiated power with RF620R/RF630R readersThe SIMATIC RF620R (ETSI) reader has a maximum radiated power of 0.5 W ERP. The maximum safety distance is therefore 0.12 m.The SIMATIC RF630R (ETSI) reader has a maximum transmitter power of 0.5 W. The radiated power therefore depends on the antenna cable and the type of antenna used, but must not exceed the 2 W ERP. 2.3.3 Minimum distance to antenna in accordance with FCC (USA)Minimum distance to antenna in accordance with FCC (USA)For the maximum permisisble transmission power in accordance with FCC (4W EIRP), the "safety distance" d = 0.26 m. This means that personnel should not remain closer than 26cm to the transmitter antenna for extended periods (more than several hours without interruption). Remaining within the vicinity of the antenna for brief period, even repeated periods (at a distance < 0.26 m) is harmless to health according to current knowledge. The horizontal line at 41.25 V/m marks the "safety limit value".Distance to transmitter antenna [m] Feld strength [V/m] % of limit value110,9 265 2,2 5,3If the transmitter power is set lower than the highest permissible value (4 watts ERP), the "safety distance" reduces correspondingly.

System overview 33.1 RF System SIMATIC RF600 SIMATIC RF600 is an identification system that operates in the UHF range. UHF technology supports large write/read distances with passive tags. The SIMATIC RF670R reader and RF660R reader (write/read devices), fitted for example on the gate of a warehouse, automatically record every movement of goods, and signal these to the host systems. The data are filtered and compressed there by data management software at the control level in order, for example, to generate the receiving department transaction for the ERP (Enterprise Resource Planning) system at the business administration control level. At the same time, the delivery can be automatically checked for correctness and completeness prior to storage by means of the electronic delivery list.The general automation and IT structure of a company is shown in the following figure. This comprises several different levels that are described in detail below. SIMATIC RF600System Manual, 06/2010, J31069-D0171-U001-A10-7618 21 Draft Version 02.06.2010
Figure 3-1 System overview of SIMATIC RF600●Acquisition levelThis level contains the RFID readers that read the appropriate tag data and transfer them to the next highest level.●Control levelAt the control level , the RFID data are collected, preprocessed and presented to the production control and business administration control levels for further processing.System overview3.1 RF System SIMATIC RF600SIMATIC RF60022 System Manual, 06/2010, J31069-D0171-U001-A10-7618 Draft Version 02.06.2010
●Production controlThe Manufacturing Execution System (MES) closes the gap between the data that arise in the automation environment (control level) and the logistical and commercial processes of the company (business administration control). MES solutions are used, for example, for defining and performing production processes.●Business administration controlThis level covers planning and control of the equipment used. For this purpose, Enterprise Resource Planning (ERP) systems and Supply Chain Management (SCM) systems are used with modules for cost accounting, financial bookkeeping and personnel management.●Global integrationProduct information can be exchanged here at an inter-company level. This can be performed over the Internet with the help of special services. 3.1.1 Application areas of RF600RFID (radio frequency identification) permits interruption-free tracking and documentation of all delivered, stocked and shipped goods in the incoming goods, warehouse, production logistics and distribution departments. A small data medium - referred to as SmartLabel, transponder or tag - is attached to every item, package or pallet, and contains all important information. The data medium receives the power it requires via an antenna which is also used for data transmission. 3.1.2 System components (hardware/software)RF600 products DescriptionDue to its compact format and high degree of protection, the RF670R reader is ideally suited to applications in production logistics and distribution.

RF600 system planning 44.1 OverviewYou should observe the following criteria for implementation planning:● Possible system configurations● Antenna configurations● Environmental conditions for transponders●The response of electromagnetic waves in the UHF band● Regulations applicable to frequency bands● EMC Directives4.2 Possible system configurations The SIMATIC RF600 system is characterized by a high level of standardization of its components. This means that the system follows the TIA principle throughout: Totally Integrated Automation. It provides maximum transparency at all levels with its reduced interface overhead. This ensures optimum interaction between all system components. The RF600 system with its flexible components offers many possibilities for system configuration. This chapter shows you how you can use the RF600 components on the basis of various example scenarios. 4.2.1 Scenario for incoming goodsThis example scenario shows the incoming goods bay of a warehouse. Pallets of goods are delivered through the incoming goods portal of a warehouse. Each pallet is equipped with a SIMATIC RF600System Manual, 06/2010, J31069-D0171-U001-A10-7618 29 Draft Version 02.06.2010
tag. The tags contain user data that provide information about the sender and receiver of the goods. These data are read out and routed on.Figure 4-1 Incoming goods bayFeatures of the scenarioIn this example, the maximum number of 4 antennas of the SIMATIC°RF660A type are connected to the SIMATIC°RF670R reader. The four antennas are aligned with one read point and therefore form a portal that is to be monitored. The reading ranges depend on the size of the portal as well as the density of readers. The tags in this scenario are Smart Labels of type SIMATIC°RF630L. They are usually attached to a non-metallic base such as wooden crates or cartons, in which the goods are packed. The tags can be mounted in almost any position on the packaging or pallet. The tags are read with the "Bulk reading" procedure in the incoming goods bay, i.e. a large number of items and many tags can be acquired at once. High read rates can be achieved in this manner.

The SIMATIC RF670R reader is connected to an RF‑MANAGER workstation that is connected, in turn, to an enterprise system through an ALE interface. The tag data can be managed by means of the enterprise system.Summary of the features NoteNote that the following features show sample values for the scenario. The specific data for your application may deviate from these values.

The objective is to provide the right material at the right time. This can be RF600 system planning4.2 Possible system configurationsSIMATIC RF600System Manual, 06/2010, J31069-D0171-U001-A10-7618 31 Draft Version 02.06.2010
particularly useful in plants with frequently changing manufacturing scenarios for ensuring that incorrect infeed and downtimes are minimized.Features of the scenarioThe conveyor moves different transport containers past the readers in an arbitrary alignment. The RFID tag is, however, always applied to the transport containers with the same alignment. The tags in this scenario are transponders of type SIMATIC RF620T.The conveyor has a maximum width of 80 cm in this example. The transport velocity is up to 2 m/s. With this arrangement only a single RFID tag has to be detected each time (single-tag).In this scenario a SIMATIC RF630R is used as the reader. Optimum reading reliability is ensured by two external SIMATIC RF660A antennas in a portal arrangement. Where the distances to, or between, the materials containers are extremely short the SIMATIC RF620A is an excellent alternative. The SIMATIC°RF630R reader reads the information from the tags on the transport containers and transfers it via a communication module to the SIMATIC S7 controller which controls the process in accordance with the tag information.Summary of the features NoteNote that the following features show sample values for the scenario. The specific data for your application may deviate from these values.

The individual data and production steps are stored in the tag of a toolholder or product. These data are read by the machining stations during a production process and, if necessary, tagged with status information. This can be used to dynamically identify which production step is the next in the series. This has the advantage that the production line can work automatically without the need to access higher system components. The use of RFID therefore increases the availability of the plant.RF600 system planning4.2 Possible system configurationsSIMATIC RF600System Manual, 06/2010, J31069-D0171-U001-A10-7618 33 Draft Version 02.06.2010
Features of the scenarioRFID tags are attached to workpiece holders. Their spatial orientation is always identical. With this arrangement, only a single tag has to be detected each time (single-tag). The tags in this scenario are transponders of type SIMATIC RF640T.The SIMATIC RF620R reader reads the information from the tags with its integrated antenna and transfers it to the SIMATIC S7 controller via a communication module. Depending on the stored tag information, the SIMATIC-S7 performs different control tasks, for example, automatically providing a suitable tool for an industrial robot at the correct time.Summary of the features NoteNote that the following features show sample values for the scenario.

The main task of Intra logistics is to control the subsequent processes:● Transporting goods from the incoming goods bay into the warehouse● Management of stock● Conveyance of goods from the warehouse for productionRF600 system planning4.2 Possible system configurationsSIMATIC RF60034 System Manual, 06/2010, J31069-D0171-U001-A10-7618 Draft Version 02.06.2010
● Order picking● PackingFeatures of the scenarioIn this example scenario. items must be distributed to the correct storage location in a transport container via a separating filter. The RFID tags of type SIMATIC RF630L are directly attached to the item. The maximum transport velocity of the conveyor is 2 m/s.In this scenario, bulk acquisition is necessary because several objects must be detected at the same time.The SIMATIC RF630R reader uses two external antennas in a portal arrangement to read the information from the tags on the passing items and transfers it to the SIMATIC S7 controller via a communication module. The SIMATIC S7 controls the separating filter of the conveyor system depending on the tag information.If only one simple evaluation of the tag ID is required, and the data will not undergo further processing, the SIMATIC RF670R offers this function without interfacing to the controller.RF600 system planning4.2 Possible system configurationsSIMATIC RF600System Manual, 06/2010, J31069-D0171-U001-A10-7618 35 Draft Version 02.06.2010
The SIMATIC RF610M mobile handheld terminal is used in this example for additional analysis and visualization of the item data directly on-site. The mobile handheld terminal can transfer the data to SIMATIC RF-MANAGER over the WLAN, and this then controls the separating filter via the SIMATIC S7 controller.Summary of the features NoteNote that the following features show sample values for the scenario.

Pallets are dispatched through the outgoing goods portals - each pallet is marked with a tag. These tags also contain user data that provide information about the sender and receiver of the goods. The data read by the readers are checked to ensure that the pallets are waiting at RF600 system planning4.2 Possible system configurationsSIMATIC RF60036 System Manual, 06/2010, J31069-D0171-U001-A10-7618 Draft Version 02.06.2010
the correct outgoing goods portal. Depending on the read results of the reader, the outgoing portal opens, or it remains closed.Figure 4-2 Outgoing goodsIn this example, the maximum number of 4 antennas of the SIMATIC°RF660A type are connected to the SIMATIC°RF670R reader. The four antennas form two different read points and therefore monitor two loading gates. The reading ranges depend on the size of the portal as well as the density of readers. The tags in this scenario are Smart Labels of type SIMATIC°RF630L. They are usually attached to a non-metallic base such as wooden crates or cartons, in which the goods are packed. The tags can be mounted in almost any position on the packaging or pallet.

RF630R reader. No external antennas can be connected to the RF620R reader. It has an integrated antenna. Antenna configuration 1: Description/ application areas This arrangement of antennas is appropriate when the tags to be read are only located on one side of the goods to be acquired, for example, if a conveyor with passing goods has to be monitored during production and it is precisely defined on which side the tags to be read are attached.① TagThis antenna configuration is possible with the following readers:● RF670R with one antenna● RF630R with one antenna● RF620RAntenna configuration 2: Description/ application areas This arrangement of antennas is appropriate when the tags to be read are only located on one side of the items to be identified, e.g. when pallets are to be identified on which the tags to be read must be on a prespecified side.① TagThis antenna configuration is possible with the following readers:● RF670R with two antennas● RF660R with two antennas● RF630R with two antennas RF600 system planning4.3 Antenna configurationsSIMATIC RF60040 System Manual, 06/2010, J31069-D0171-U001-A10-7618 Draft Version 02.06.2010
Antenna configuration 3: Description/ application areasPreferred for the identification of goods at loading portals: The tag is located in the field of radiation of two antennas; for reliable tag reading, the height of the tag above floor level must therefore be known with reasonable accuracy.① TagThis antenna configuration is possible with the following readers:● RF670R with two antennas● RF660R with two antennas● RF630R with two antennasAntenna configuration 4: Description/ application areasPreferred for the identification of goods at loading portals: Similar to configuration 2, but with additional reading reliability when the tag is at an angle to the vertical.① TagThis antenna configuration is possible with the following readers:● RF670R with three antennas● RF660R with three antennasRF600 system planning4.3 Antenna configurationsSIMATIC RF600System Manual, 06/2010, J31069-D0171-U001-A10-7618 41 Draft Version 02.06.2010
Antenna configuration 5: Description/ application areasPreferred for the identification of goods at loading portals: The tag is located in the field of radiation of all four antennas, so the tag position can vary more than in configuration 2 for reliable tag identification.① TagThis antenna configuration is possible with the following readers:● RF670R with four antennas● RF660R with four antennasAntenna configuration 6: Description/ application areasPreferred for the identification of goods at loading portals: Similar to configuration 4, but the reliability of tag identification is improved as a result of the four antennas at separate locations, so the tag position is not critical.① TagThis antenna configuration is possible with the following readers:● RF670R with four antennas● RF660R with four antennasRF600 system planning4.3 Antenna configurationsSIMATIC RF60042 System Manual, 06/2010, J31069-D0171-U001-A10-7618 Draft Version 02.06.2010
Antenna configuration 7: Description/ application areas This tunnel configuration is suitable for conveyor belt applications. The goods with the tags to be read are moving forwards on a conveyor belt but the alignment of the tags relative to the antennas is not clearly defined. One of the antenna is located on the floor and radiates vertically upwards in the direction of the conveyor belt. A relatively high reading reliability is achieved due to the use of four antennas.① TagThis antenna configuration is possible with the following readers:● RF670R with four antennas● RF660R with four antennas4.3.3 Tag orientation in spaceThe alignment of the tag antenna to the antenna of the reader affects the reading range. For maximum performance and to achieve the maximum reading range, the tag antenna should therefore be aligned in parallel with the reader antenna: Parallel tag alignment Large reading rangeMaximum probability of identification of tags.Vertical tag alignment Minimal reading rangeMinimum probability of identification of tags.RF600 system planning4.3 Antenna configurationsSIMATIC RF600System Manual, 06/2010, J31069-D0171-U001-A10-7618 43 Draft Version 02.06.2010
4.3.4 Specified minimum and maximum spacing of antennasSpecified minimum spacing of antennasThe following diagram shows the specified minimum and maximum spacings for mounting antennas: A minimum spacing of 50 cm is necessary between the antenna and liquids or metals.The distance between the antenna and the floor should also be at least 50 cm.Figure 4-4 Minimum distance to the environment The distance between two antennas mounted alongside each other or one above the other should be at least 20 cm, but a distance of more than 50 cm is better.RF600 system planning4.3 Antenna configurationsSIMATIC RF60044 System Manual, 06/2010, J31069-D0171-U001-A10-7618 Draft Version 02.06.2010

The specified distances are recommended minimum or maximum values for configuration.4.3.5 Mutual interference of readers (antennas)Using more than one readerWhen several RFID readers are used, there is a danger that RFID tags can also be read byother readers. It must be ensured that the tag can only be identified by the appropriate reader.Technical faults between readers then occur particularly when they transmit on the same channel (on the same frequency). To prevent this, readers used in Europe and China must operate on different channels with "Frequency hopping" activated. "Frequency hopping" is permanently set in the USA.4.3.6 Reading rangeThe reading range between the reader (antenna) and the transponder is affected by the following factors: The reading range depends on DescriptionTransmit power of the reader The higher the transmit power of the reader, the larger the reading range.Tag size and type The larger the tag antenna, the larger the power input area and therefore the larger the reading range.Absorption factor of the materials The higher the absorption of the surrounding material, the smaller the reading range.Production quality of the tag The better the tag has been matched to the operating frequencies during manufacturing, the greater the reading range.Reflection characteristics of the environmentIn a multiple-reflection environment (e.g., in rooms with reflecting surfaces, machinery, or concrete walls), the reading range can be significantly higher than in a low-reflection environment.You will find detailed information about the reading range of the individual readers in the "Technical specifications" in the sections for the various readers. 4.3.7 Operation of several readers within restricted space4.3.7.1 Dense Reader ModeA special operating mode for Gen 2 tags enables several RF600 readers to be operated without interference in close proximity to each other. This applies to all RF600 readers: RF670R, RF660R, RF630R and RF620R.RF600 system planning4.3 Antenna configurationsSIMATIC RF60046 System Manual, 06/2010, J31069-D0171-U001-A10-7618 Draft Version 02.06.2010
Dense Reader Mode (DRM)In this mode, tag readability is increased through the application of interference-reducing measures.DRM is only defined for Gen 2 and does not function with other tag types.Operating principleDense Reader Mode allows physically adjacent readers to use the same frequency when Gen 2 tags are being used. In accordance with EPC Global as well as ETSI EN 302 208 V1.2.1, the four transmit channels are used for transmission with the RF670R, with the RF660R in Firmware Version V1.3 and higher, and with the RF620R/RF630R (see Section Regulations for UHF frequency bands in Europe (ETSI EN 302 208 V1.2.1) (Page 54)) and the tag response appears on the associated neighboring channels. As a result of the large difference in level between the transmitter channels and the tag response channels, this technology provides great advantages for frequency reuse. However, a prerequisite is that a certain minimum distance, and thus minimum decoupling, is observed between the antennas of adjacent readers. In accordance with EPC Global as well as ETSI EN 302 208 V1.1.1, only the even channels are used for transmitting in this mode (communications path Reader -> Tag) with the RF660R in Firmware Version V1.2 and below; the tag response is on the odd channels as a result of the frequency offset.Antenna alignment and distancesThe minimum distance required between antennas that use the same frequency and that are connected to different readers depends on the maximum radiated power set (RF670R with RF600 system planning4.3 Antenna configurationsSIMATIC RF600System Manual, 06/2010, J31069-D0171-U001-A10-7618 47 Draft Version 02.06.2010

This greatly reduces the probability of interference.RF600 system planning4.3 Antenna configurationsSIMATIC RF60048 System Manual, 06/2010, J31069-D0171-U001-A10-7618 Draft Version 02.06.2010
4.3.7.3 Optimization of robustness of tag data accesses for readers that are operated simultaneouslyParameter data access reliabilityIf several readers are to be operated simultaneously in an environment, then the following settings affect the reliability of the reader's access to transponder data:● Electromagnetic environment (see Chapter The response of electromagnetic waves in the UHF band (Page 51))● Type of transponder (see chapter Transponder/tags (Page 205))● Number of transponders to be detected by an antenna at a time● Type of antenna (see Chapter Antennas (Page 153), Chapter Guidelines for selecting RFID UHF antennas (Page 181), and Chapter Planning application (Page 84))● Transponders' distance from and orientation toward antennas (see Chapter Transponder/tags (Page 205))● Distances and orientation of antennas of different readers to each other● Radiated power of antennasThe robustness of tag data accesses is improved for readers whenever distances to adjacent readers are increased, radiated power is reduced, and a channel plan (for ETSI readers) is implemented. Adjacent readers are parameterized in the channel plan such that they cannot use the same channels. A channel plan can be created for ETSI readers; for FCC readers, it is assumed that the probability of two readers accidentally using the same channel is very low. SIMATIC RF620R readerThe RF620R has an integrated, circular polarized antenna. This means that the type of antenna cannot be freely selected. NoteRotation of the reader through 90° around the z axisSince the horizontal electrical opening angle of the RF620R antenna is greater than the vertical electrical opening angle, the effects on adjacent readers can be reduced by rotating the reader through 90° around the z axis (see coordinate diagram in Chapters Antenna diagram for RF620R (ETSI) (Page 85) and Antenna diagram for RF620R (FCC) (Page 88)). SIMATIC RF670R, RF630R or RF660R reader with SIMATIC RF660A antennaThe electrical opening angles (vertical and horizontal) of the RF660A antenna are identical. Therefore, the robustness of the readers' access to transponder data cannot be optimized further by rotating them around the antenna axis.RF600 system planning4.3 Antenna configurationsSIMATIC RF600System Manual, 06/2010, J31069-D0171-U001-A10-7618 49 Draft Version 02.06.2010
Application example for RF620R/RF630RThe following example explains measures for enhancing the data access security from the RF620R reader to transponders:● The antennas are placed next to each other and are aligned in parallel (see arrangement B in Chapter Dense Reader Mode (Page 46)).● Radiated power is limited to 27 dBm (ERP) or 500 mW (ERP).● The RF620R readers have been rotated through 90° around the z axis.In addition, the following characteristics are to be fulfilled:● Length of data to be read/written on the transponder: 99,99%● Length of data to be read/written on the transponder: 512 bits (64 bytes)● Transponder type RF630L (6GT2810-2AB03)The table below provides an overview of the minimum distances to be observed depending on the radiated power and maximum possible number of transponders for the RF620R/RF630R readers if the above-named requirements must be fulfilled:Mode Max. number of tagsRadiated powerdBm (ERP)/ mW (ERP)Min. distance [m] between - two RF620R readers - two RF660A antennas operated with RF630R readers - one RF620R and one RF660A antenna operated with a RF630R readerSingle tag mode: Read1 27 dBm (ERP)/ 500 mW (ERP)3Single tag mode: Write1 27 dBm (ERP)/ 500 mW (ERP)3Multitag mode: Read40 27 dBm (ERP)/ 500 mW (ERP)6Multitag mode: Write10 27 dBm (ERP)/ 500 mW (ERP)6See alsoRF660A antenna (Page 175)4.3.7.4 Frequency hoppingThis technique should prevent mutual interference between readers. The reader changes its transmission channel in a random or programmed sequence (FHSS). Procedure for FCCThe 50 available channels mean that the probability is low that two readers will be operating on the same frequency (see Section Regulations for UHF frequency bands in the USA (Page 60)). In China, one reader operates on at least 2 channels, e.g. 16 channels of 2 W (see Section Regulations for UHF frequency bands in China (Page 58)). RF600 system planning4.3 Antenna configurationsSIMATIC RF60050 System Manual, 06/2010, J31069-D0171-U001-A10-7618 Draft Version 02.06.2010
Procedure for ETSIFrequency hopping is optional here. According to ETSI EN 203 208 V1.2.1, frequency hopping is however recommended to ensure that the reader does not have to pause for 100 ms after 4 seconds.4.3.7.5 Listen before talkWith this technique which is only applicable to ETSI, the reader checks whether the relevant channel is assigned before transmission to prevent collisions. The reader will only transmit when this channel is free. The reader can transmit for up to 4 seconds on this channel and must then either pause for at least 100 milliseconds or jump immediately to an unassigned channel where it can transmit for another 4 seconds.With the new ETSI EN 302 208 standard V1.2.1 this technique must be not be used (see Chapter Regulations for UHF frequency bands in Europe (ETSI EN 302 208 V1.1.2) (Page 57) and Chapter Regulations for UHF frequency bands in Europe (ETSI EN 302 208 V1.2.1) (Page 54) ).4.4 Environmental conditions for transponders/tags4.4.1 Basic rulesThe transponder/tag must not be placed directly on metal surfaces or on containers of liquid. For physical reasons, a minimum distance must be maintained between the tag antenna and conductive material. A minimum distance of 5 cm is recommended. The tag operates better when the distance is greater (between 5 and 20 cm).● Tag assembly on non-conductive material (plastic, wood) has a tendency to be less critical than assembly even on poorly conductive material.● The best results are achieved on the materials specified by the tag manufacturer.● You can obtain more detailed information from the tag manufacturer.4.5 The response of electromagnetic waves in the UHF band4.5.1 The effect of reflections and interferenceReflections and interferenceElectromagnetic waves in the UHF band behave and propagate in a similar manner to light waves, that is they are reflected from large objects such as ceilings, floors, walls and windows and interfere with each other. Due to the nature of electromagnetic waves, interference can lead to wave amplification which can produce an increased reading range. In the worst case, RF600 system planning4.5 The response of electromagnetic waves in the UHF bandSIMATIC RF600System Manual, 06/2010, J31069-D0171-U001-A10-7618 51 Draft Version 02.06.2010
interference can also result in waves being extinguished which causes holes in reader coverage.Reflections can also be beneficial when they cause electromagnetic waves to be routed around objects to a certain extent (deflection). This can increase the reading probability.Due to these electromagnetic characteristics, it is extremely difficult in the multiple-reflection environment that is usually found in the real environment on site, to determine propagation paths and field strengths for a particular location.Reducing the effect of reflections/interference on tag identification● Reducing the transmit power: To reduce interference to a minimum, we recommend that the transmitter power of the reader is reduced until it is sufficient for an identification rate of 100%.● Increasing the number of antennas to 3 or 4: More antennas in a suitable antenna configuration can prevent gaps in reader coverage.4.5.2 Influence of metalsMetal can have an effect on the electromagnetic field depending on the arrangement or environment. The effect ranges from a hardly determinable influence through to total blocking of communication. The term metal in this context also includes metallized materials that are either coated with metal or shot through with metal to such an extent that UHF radiation cannot penetrate or only to a minimal extent. The effect of metal on the electromagnetic field can be prevented as follows:● Do not mount tags on metal.● Do not place metallic or conducting objects in the propagation field of the antenna and transponder.Tags mounted directly onto metalIn general, tags must not be mounted directly onto metallic surfaces. Due to the nature of the magnetic field, a minimum distance must be maintained between the tag antenna and conductive materials. For further details on the special case of attaching transponders to electrically conducting materials, see Section SIMATIC RF620T (Page 235) and SectionSIMATIC RF640T (Page 271) .In the case of transponders that are not designed for mounting on metallic materials, the minimum permissible distance from metal is 5 cm. The larger the distance between the transponder and the metallic surface, the better the function of the transponder.4.5.3 Influence of liquids and non-metallic substancesNon-metallic substances can also affect the propagation of electromagnetic waves. RF600 system planning4.5 The response of electromagnetic waves in the UHF bandSIMATIC RF60052 System Manual, 06/2010, J31069-D0171-U001-A10-7618 Draft Version 02.06.2010
When non-metallic substances or objects are located in the propagation field that can absorb UHF radiation, these can alter the antenna field depending on their size and distance and can even extinguish the field entirely.The high-frequency damping effect of water and materials with a water content, ice and carbon is high. Electromagnetic energy is partly reflected and absorbed.Liquids and petroleum-based oils have low HF damping. Electromagnetic waves penetrate the liquid and are only slightly weakened.4.5.4 Influence of external componentsThe R&TTE guideline and the relevant standards govern the electromagnetic compatibility requirements. This also concerns the external components of the RF600 system. Even though the requirements for electromagnetic compatibility have been specified, various components will still interfere with each other. The performance of the RF600 system is highly dependent on the electromagnetic environment of the antennas.Reflections and interferenceOn the one hand, antenna fields will be weakened by absorbing materials and reflected by conducting materials. When electromagnetic fields are reflected, the antenna field and reflecting fields overlap (interference).External components in the same frequency bandOn the other hand, external components can transmit on the same frequency band as the reader. Or the external components can transmit in different frequency bands with side bands that overlap with the frequency band of the reader. This results in a reduction of the "signal-to-noise" ratio which reduces the performance of an RF600 system.If a DECT station that is transmitting in the 2 GHz band, for example, is located in the receiving range of an antenna of the RF600 system, the performance of the write and read accesses to the transponder will be affected.4.6 Regulations applicable to frequency bands The following section describes the regulations for frequency bands which apply in different regions with reference to RFID.

Reasons for interferenceThe following reasons may cause the interference:● Only four transmission channels (865.7; 866.3; 866.9; 867.5 MHz) are now available according to the latest ETSI standard.● Deactivation of Listen Before Talking (LBT)● When operating readers in mixed mode according to the old ETSI standard (EN 302 208 V1.1.1) and the new ETSI standard (EN 302 208 V1.2.1), the transmission and receive channels may interfere with each other. Tag reading might thus be blocked.

This means that neither the transmission channels nor the receive channels of the readers operated according EN 302 208 V1.1.1 must overlap with the transmission or receive channels of the readers operated according to EN 302 208 V1.2.1.Procedure1. In the channel plan, only mark the transmission channels as assigned channels of a reader for all readers that are not to operated in dense mode (EPC Global Class 1 Gen 1, EPC Global Class 1 Gen 2 (no dense mode)) or ISO 18000-6B).2. For all readers that are to operate in dense mode (EPC Global Class 1 Gen 1, EPC Global Class 1 Gen 2 (dense mode)), mark the transmission channels and the channels right next to them (receive channels) as assigned channels of a reader.3. For this purpose, first mark all transmission channels and any adjacent receive channels in dense mode operation of the R660R readers for V1.3 or later versions in the channel plan. In mixed operation, the RF660R reader operated according to EN 302 208 V1.1.1 can use more channels than an RF660R reader operated according to EN 302 208 V1.2.1.4. Then mark all transmission channels and any adjacent receive channels in dense mode operation of the R660R readers for V1.2 or earlier versions in the channel plan.RF600 system planning4.7 Operation of RF600 readers according to EN 302208 V1.2.1 and EN 302208 V1.1.1SIMATIC RF60064 System Manual, 06/2010, J31069-D0171-U001-A10-7618 Draft Version 02.06.2010
Example of planning a channel planBelow you will find a concrete example of a channel plan with which you prevent interference:● New readers operating according to EN 302 208 V1.2.1 must use channels with a channel number below 107. Dense mode can be activated or deactivated.● Readers according to the old standard EN 302 208 V1.1.1 can use channels with a channel number between 109 and 114. If dense mode is activate, only even-numbered channels can be used.Such a setting prevents that readers interfere with each other. At which channel number the separation will be depends on the ratio of readers according to the old standard and new standard. This limit can be shifted as required.4.7.3.3 Example 1: Recommended channel assignment mixed operationThis case refers to mixed operation of several readers according to EN 302 208 V1.1.1 with standard profile and several readers according to EN 302 208 V1.2.1 in dense mode.Transmission by reader 1 - according to EN 302208 V1.2.1 (4-channel plan, dense mode)Transmission by reader 2 - according to EN 302208 V1.1.1 (15 channels, LBT)Receiving by reader 1 - according to EN 302208 V1.2.1 (4-channel plan, dense mode)Receiving by reader 2 - according to EN 302208 V1.1.1 (15 channels, LBT)Figure 4-12 Recommended channel assignment mixed operation RF600 system planning4.7 Operation of RF600 readers according to EN 302208 V1.2.1 and EN 302208 V1.1.1SIMATIC RF600System Manual, 06/2010, J31069-D0171-U001-A10-7618 65 Draft Version 02.06.2010

● Which standards relate to EMC?● Examples of interference-free plant design The description is intended for "qualified personnel":● Project engineers and planners who plan system configurations with RFID modules and have to observe the necessary guidelines.● Fitters and service engineers who install the connecting cables in accordance with this description or who rectify defects in this area in the event of interference. NOTICEFailure to observe notices drawn to the reader's attention can result in dangerous conditions in the plant or the destruction of individual components or the entire plant. 4.8.2 What does EMC mean?The increasing use of electrical and electronic devices is accompanied by:● Higher component density● More switched power electronics● Increasing switching rates●Lower power consumption of components due to steeper switching edgesThe higher the degree of automation, the greater the risk of interaction between devices.Electromagnetic compatibility (EMC) is the ability of an electrical or electronic device to operate satisfactorily in an electromagnetic environment without affecting or interfering with the environment over and above certain limits. EMC can be broken down into three different areas:● Intrinsic immunity to interference:immunity to internal electrical disturbance● Immunity to external interference:immunity to external electromagnetic disturbance● Degree of interference emission:emission of interference and its effect on the electrical environmentAll three areas are considered when testing an electrical device.The RFID modules are tested for conformity with the limit values required by the CE and RTTE guidelines. Since the RFID modules are merely components of an overall system, and sources of interference can arise as a result of combining different components, certain guidelines have to be followed when setting up a plant.EMC measures usually consist of a complete package of measures, all of which need to be implemented in order to ensure that the plant is immune to interference. RF600 system planning4.8 Guidelines for electromagnetic compatibility (EMC)SIMATIC RF60070 System Manual, 06/2010, J31069-D0171-U001-A10-7618 Draft Version 02.06.2010
NoteThe plant manufacturer is responsible for the observance of the EMC guidelines; the plant operator is responsible for radio interference suppression in the overall plant.All measures taken when setting up the plant prevent expensive retrospective modifications and interference suppression measures.The plant operator must comply with the locally applicable laws and regulations. They are not covered in this document. 4.8.3 Basic rulesIt is often sufficient to follow a few elementary rules in order to ensure electromagnetic compatiblity (EMC). The following rules must be observed: Shielding by enclosure●Protect the device against external interference by installing it in a cabinet or housing. The housing or enclosure must be connected to the chassis ground.● Use metal plates to shield against electromagnetic fields generated by inductances.● Use metal connector housings to shield data conductors.Wide-area ground connection●Bond all passive metal parts to chassis ground, ensuring large-area and low-HF-impedance contact.● Establish a large-area connection between the passive metal parts and the central grounding point.● Don't forget to include the shielding bus in the chassis ground system. That means the actual shielding busbars must be connected to ground by large-area contact.● Aluminium parts are not suitable for ground connections.Plan the cable installation● Break the cabling down into cable groups and install these separately.● Always route power cables, signal cables and HF cables through separated ducts or in separate bundles.● Feed the cabling into the cabinet from one side only and, if possible, on one level only.● Route the signal cables as close as possible to chassis surfaces.● Twist the feed and return conductors of separately installed cables.RF600 system planning4.8 Guidelines for electromagnetic compatibility (EMC)SIMATIC RF600System Manual, 06/2010, J31069-D0171-U001-A10-7618 71 Draft Version 02.06.2010
● Routing HF cables:avoid parallel routing of HF cables.● Do not route cables through the antenna field.Shielding for the cables● Shield the data cables and connect the shield at both ends.● Shield the analog cables and connect the shield at one end, e.g. on the drive unit.●Always apply large-area connections between the cable shields and the shielding bus at the cabinet inlet and make the contact with clamps.● Feed the connected shield through to the module without interruption.● Use braided shields, not foil shields.Line and signal filter● Use only line filters with metal housings● Connect the filter housing to the cabinet chassis using a large-area low-HF-impedance connection.● Never fix the filter housing to a painted surface.● Fix the filter at the control cabinet inlet or in the direction of the source.4.8.4 Propagation of electromagnetic interferenceThree components have to be present for interference to occur in a system: ● Interference source● Coupling path● Interference sinkFigure 4-15 Propagation of interferenceIf one of the components is missing, e.g. the coupling path between the interference source and the interference sink, the interference sink is unaffected, even if the interference source is transmitting a high level of noise. The EMC measures are applied to all three components, in order to prevent malfunctions due to interference. When setting up a plant, the manufacturer must take all possible measures in order to prevent the occurrence of interference sources:RF600 system planning4.8 Guidelines for electromagnetic compatibility (EMC)SIMATIC RF60072 System Manual, 06/2010, J31069-D0171-U001-A10-7618 Draft Version 02.06.2010
● Only devices fulfilling limit class A of VDE 0871 may be used in a plant.● Interference suppression measures must be introduced on all interference-emitting devices. This includes all coils and windings.● The design of the system must be such that mutual interference between individual components is precluded or kept as small as possible.Information and tips for plant design are given in the following sections.Interference sourcesIn order to achieve a high level of electromagnetic compatibility and thus a very low level of disturbance in a plant, it is necessary to recognize the most frequent interference sources. These must then be eliminated by appropriate measures.Table 4-1 Interference sources: origin and effectInterference source Interference results from Effect on the interference sinkContactors,electronic valvesContacts System disturbancesCoils Magnetic fieldElectrical motor Collector Electrical fieldWinding Magnetic fieldElectric welding device Contacts Electrical fieldTransformer Magnetic field, system disturbance, transient currentsPower supply unit, switched-modeCircuit Electrical and magnetic field, system disturbanceHigh-frequency appliances Circuit Electromagnetic fieldTransmitter(e.g. service radio)Antenna Electromagnetic fieldGround or reference potential differenceVoltage difference Transient currentsOperator Static charge Electrical discharge currents, electrical fieldPower cable Current flow Electrical and magnetic field, system disturbanceHigh-voltage cable Voltage difference Electrical fieldRF600 system planning4.8 Guidelines for electromagnetic compatibility (EMC)SIMATIC RF600System Manual, 06/2010, J31069-D0171-U001-A10-7618 73 Draft Version 02.06.2010

There are four ways in which interference can be coupled in: Figure 4-16 Ways in which interference can be coupled in RF600 system planning4.8 Guidelines for electromagnetic compatibility (EMC)SIMATIC RF60074 System Manual, 06/2010, J31069-D0171-U001-A10-7618 Draft Version 02.06.2010
When RFID modules are used, different components in the overall system can act as a coupling path:Table 4-2 Causes of coupling pathsCoupling path Invoked byConductors and cables ● Incorrect or inappropriate installation●Missing or incorrectly connected shield● Inappropriate physical arrangement of cablesControl cabinet or housing ● Missing or incorrectly wired equalizing conductor● Missing or incorrect earthing● Inappropriate physical arrangement● Components not mounted securely●Unfavorable cabinet configuration4.8.5 Prevention of interference sourcesA high level of immunity to interference can be achieved by avoiding interference sources. All switched inductances are frequent sources of interference in plants. Suppression of inductanceRelays, contactors, etc. generate interference voltages and must therefore be suppressed using one of the circuits below.Even with small relays, interference voltages of up to 800 V occur on 24 V coils, and interference voltages of several kV occur on 230 V coils when the coil is switched. The use of freewheeling diodes or RC circuits prevents interference voltages and thus stray interference on conductors installed parallel to the coil conductor.Figure 4-17 Suppression of inductance RF600 system planning4.8 Guidelines for electromagnetic compatibility (EMC)SIMATIC RF600System Manual, 06/2010, J31069-D0171-U001-A10-7618 75 Draft Version 02.06.2010
NoteAll coils in the cabinet should be suppressed. The valves and motor brakes are frequently forgotten. Fluorescent lamps in the control cabinet should be tested in particular. 4.8.6 Equipotential bondingPotential differences between different parts of a plant can arise due to the different design of the plant components and different voltage levels. If the plant components are connected across signal cables, transient currents flow across the signal cables. These transient currents can corrupt the signals.Proper equipotential bonding is thus essential. ● The equipotential bonding conductor must have a sufficiently large cross section (at least 10 mm2).● The distance between the signal cable and the associated equipotential bonding conductor must be as small as possible (antenna effect).● A fine-strand conductor must be used (better high-frequency conductivity).● When connecting the equipotential bonding conductors to the centralized equipotential bonding strip (EBS), the power components and non-power components must be combined.● The equipotential bonding conductors of the separate modules must lead directly to the equipotential bonding strip.Figure 4-18 Equipotential bonding (EBS = Equipotential bonding strip)The better the equipotential bonding in a plant, the smaller the chance of interference due to fluctuations in potential.RF600 system planning4.8 Guidelines for electromagnetic compatibility (EMC)SIMATIC RF60076 System Manual, 06/2010, J31069-D0171-U001-A10-7618 Draft Version 02.06.2010
Equipotential bonding should not be confused with protective earthing of a plant. Protective earthing prevents the occurrence of excessive shock voltages in the event of equipment faults whereas equipotential bonding prevents the occurrence of differences in potential.4.8.7 Cable shieldingSignal cables must be shielded in order to prevent coupling of interference.The best shielding is achieved by installing the cables in steel tubes. However, this is only necessary if the signal cable is routed through an environment prone to particular interference. It is usually adequate to use cables with braided shields. In either case, however, correct connection is vital for effective shielding. NoteAn unconnected or incorrectly connected shield has no shielding effect. As a rule:● For analog signal cables, the shield should be connected at one end on the receiver side● For digital signals, the shield should be connected to the enclosure at both ends● Since interference signals are frequently within the HF range (> 10 kHz), a large-area HF-proof shield contact is necessaryFigure 4-19 Cable shieldingThe shielding bus should be connected to the control cabinet enclosure in a manner allowing good conductance (large-area contact) and must be situated as close as possible to the cable inlet. The cable insulation must be removed and the cable clamped to the shielding bus (high-frequency clamp) or secured using cable ties. Care should be taken to ensure that the connection allows good conductance.

Figure 4-20 Connection of shielding busThe shielding bus must be connected to the PE busbar.If shielded cables have to be interrupted, the shield must be continued via the corresponding connector housing. Only suitable connectors may be used for this purpose. Figure 4-21 Interruption of shielded cablesIf intermediate connectors, which do not have a suitable shield connection, are used, the shield must be continued by fixing cable clamps at the point of interruption. This ensures a large-area, HF-conducting contact.RF600 system planning4.8 Guidelines for electromagnetic compatibility (EMC)SIMATIC RF60078 System Manual, 06/2010, J31069-D0171-U001-A10-7618 Draft Version 02.06.2010

At 500 mW ERP radiated power, due to the opening angle of the antennas, their fields can overlap considerably. It is no longer possible to clarify in which antenna field access to the data of a tag is performed. In order to avoid this, always keep a minimum distance of 3 m between two readers with the maximum radiated power of 500 mW ERP.Dense Reader Mode (DRM)The readers can also interfere with each other (secondary fields), if the channels (Reader TX, Transponder TX) overlap. In order to prevent a transponder channel overlapping with a reader channel, we recommend that the Dense Reader Mode (DRM) is used.Readers5.1 RF620R readerSIMATIC RF60084 System Manual, 06/2010, J31069-D0171-U001-A10-7618 Draft Version 02.06.2010

The table shows which dBi values correspond to which read/write ranges (in %): You can read the radiated power depending on the reference angle from the directional radiation patterns, and thus obtain information on the read/write range with this reference angle with regard to a transponder.The dBr values correspond to the difference between the maximum dBi value and a second dBi value.Deviation from maximum antenna gain [dBr] Read/write range [%]0100-3 70-6 50-9 35-12 25-15 18-18 13ExampleAs one can see from the section Antenna diagram for RF620R (ETSI) (Page 85), the maximum antenna gain is 0 dB. In the Azimuth diagram, the antenna gain falls by 3°dB at approximately ± 39°. Therefore the dBr value is -3. The antenna range is only 50% of the maximum range at ± 39° from the Z axis within the horizontal plane.5.1.2.5 Antenna/read point configurationsThe RF620R reader has an internal circular polarized antenna. You can cover one read point with this antenna.

It is no longer possible to clarify in which antenna field access to the data of a tag is performed. In order to avoid this, always keep a minimum distance of 3 m between two antennas of different RF630R readers with the maximum radiated power of 500 mW ERP.Dense Reader Mode (DRM)The readers can also interfere with each other (secondary fields), if the channels (Reader TX, Transponder TX) overlap. In order to prevent a transponder channel overlapping with a reader channel, we recommend that the Dense Reader Mode (DRM) is used.5.2.2.2 Antenna/read point configurationsYou can connect up to two external antennas to the RF630R reader. The standard setting is that two antennas are connected when the reader is started.You have 3 possibilities for aligning the antennas and covering the read point.Readers5.2 RF630R readerSIMATIC RF600104 System Manual, 06/2010, J31069-D0171-U001-A10-7618 Draft Version 02.06.2010
One RF630R reader with two antennas and two read pointsIf you connect two external antennas to the device and align them in different directions, you can read tags at two different read points. With this technique, a particular antenna must be switched off application-dependently to be able to establish which tags have been read from which antenna. The reader also provides a mode for this purpose in which the antennas can be switched on and off cyclically (both antennas must be connected). Note the minimum distances between the antennas for the antenna configuration (see Chapter Specified minimum and maximum spacing of antennas (Page 44) . One RF630R reader with two antennas and one read pointIf you connect two external antennas to the device and align them in the same direction (portal configuration), you can read tags at one read point. With this method, the reader automatically switches between the two antennas while the tags are being read. Note the minimum distances between the antennas for the antenna configuration (see Chapter Specified minimum and maximum spacing of antennas (Page 44) . One RF630R reader with one antenna and one read pointIf you connect an external antenna to the device, you can read tags at one read point. 5.2.3 Installing/Mounting5.2.3.1 Mounting/InstallationRequirement WARNINGEnsure that the wall or ceiling can hold four times the total weight of the device.

As long as the antenna is receiving signals from further tags, the reader continues to transmit on the same transmitter antenna until all responding tags have been identified. Subsequently, or if no tags respond, the reader activates another antenna as the transmitter antenna. After all the antenna have transmitted at least once and no tag has responded, or when the settling time is excessively long, the reader activates frequency hopping (in the USA) or channel selection (in Europe).

6.2.4.4 Connecting RF620A to RF660RPreassembled standard cables (Page 155) in lengths of 3 m, 10 m and 20 m are available for the connection.The read range is limited by the cable loss. The maximum range can be achieved with the 6GT2815-0BH30 cable (length 3 m) since this has the lowest cable loss.At least two antennas must be connected in order to guarantee correct functioning.Connection of two antennasWhen two antennas are used, we recommend that the antennas be connected to the reader as follows:Figure 6-2 Configuration with RF660RThe RF620A antennas must always be arranged in pairs with the RF660R since one antenna is needed for transmitting signals to the transponder whereas the other antenna receives the signals from the transponder. NoteOperation of the RF660R with more than two RF620A antennas does not offer optimum performance!More than two antennas should not be connected due to the functional design of the reader. The optimum read rates cannot be achieved if you connect more than two RF620A antennas. 6.2.5 Alignment of transponders to the antennaPolarization axisSince the RF620A antenna has linear polarization, it is necessary to consider the alignment of the transponders with regard to the polarization axis of the antenna.

and thus obtain information on the read/write range with this reference angle with regard to a transponder.The dBr values correspond to the difference between the maximum dBi value and a second dBi value.Deviation from maximum antenna gain [dBr] Read/write range [%]0100-3 70-6 50-9 35-12 25-15 18-18 13ExampleAs one can see from the Antenna pattern ETSI (Page 163), the maximum antenna gain is -5 dBi. In the vertical plane, the antenna gain has dropped to approx. -11 dBi at +40° and 320°. Therefore the dBr value is -6. The antenna range is only 50% of the maximum range at ± 40° from the Z axis within the vertical plane (see values shown in blue in the directional radiation pattern: characteristic of the vertical plane of the antenna (Page 163) and the associated representation of the reference system (Page 163)).6.2.8 Read/write rangesThe following tables show the typical read/write ranges of RF600 readers which are connected to the RF620A antenna via the 3 m antenna cable (1 dB loss) and various types of tags. NotePlease note that tolerances of ±20% are admissible due to production and temperature conditions. When using other antenna cables, the ranges listed here are reduced as a result of the higher antenna cable losses in the following manner:Cable designation Order No. Length [m] Cable loss [dB] Read/write range [%]Antenna cable 6GT2815-0BH30 3 1 100Antenna cable 6GT2815-1BN10 10 2 90Antenna cable 6GT2815-0BN10 10 4 70Antenna cable 6GT2815-0BN20 20 4 70The measuring tolerances in the following tables are ±3 cm.Antennas6.2 RF620A antennaSIMATIC RF600System Manual, 06/2010, J31069-D0171-U001-A10-7618 169 Draft Version 02.06.2010

The radiation diagram is shown for horizontal alignment and for a center frequency of 865 MHz. Horizontal antenna alignment is provided when the TNC connection on the antenna points vertically up or down. The radiating/receiving angle of the antenna is defined by the angle between the two -3 dB points (corresponding to half the power referred to the maximum performance at a 0° angle).The optimum radiating/receiving angle is therefore approximately ±30 degrees.Figure 6-14 Directional radiation pattern of the antenna (at 865 MHz, horizontal alignment) USA (FCC)The radiation diagram is shown for horizontal alignment and for a center frequency of 915 MHz. The radiating/receiving angle of the antenna is defined by the angle between the two -3 dB points (corresponding to half the power referred to the maximum performance at a 0° angle).The optimum radiating/receiving angle is therefore approximately ±35 degrees.Antennas6.3 RF660A antennaSIMATIC RF600178 System Manual, 06/2010, J31069-D0171-U001-A10-7618 Draft Version 02.06.2010

The table shows which dBi values correspond to which read/write ranges (in %): You can read the radiated power depending on the reference angle from the directional radiation patterns, and thus obtain information on the read/write range with this reference angle with regard to a transponder.The dBr values correspond to the difference between the maximum dBi value and a second dBi value.Deviation from maximum antenna gain [dBr] Read/write range [%]0100-3 70-6 50-9 35-12 25-15 18-18 13Antennas6.3 RF660A antennaSIMATIC RF600System Manual, 06/2010, J31069-D0171-U001-A10-7618 179 Draft Version 02.06.2010
ExampleAs one can see from the section Antenna pattern (Page 177), the maximum antenna gain is 6 dBi. In the vertical plane, the antenna gain has dropped to approx. 3 dBi at +30°. Therefore the dBr value is -3. The antenna range is only 50% of the maximum range at ± 30° from the Z axis within the vertical plane.6.3.4 Installation and assembly The RF660A antenna can be fixed to any firm support.More information on the types of antenna fixing can be found in section Mounting types (Page 200).6.3.5 Connecting an antenna to a reader NOTICEUse of Siemens antenna cableTo ensure optimum functioning of the antenna, it is urgently recommended that a Siemens antenna cable is used in accordance with the list of accessories.

The various antenna and cable parameters are explained, and information is provided on the criteria you must particularly observe. Otherwise this chapter is equally suitable for theoretical and practice-oriented users.Purpose of this chapterThis chapter enables you to select the appropriate external antenna or cable with consideration of all important criteria and to carry out the corresponding settings in the configuration software of the SIMATIC RF600 system. Correct and safe integration into the SIMATIC RF600 system is only possible following adaptation of all required parameters.HistoryEdition Comment12/2007 First edition6.4.3 General application planning6.4.3.1 Overview of the total SIMATIC RF600 system and its influencing factorsThe following graphic shows the design of the total SIMATIC RF600 system and the factors which have an influence on the total system. You must be aware of these influencing factors and also consider them if you wish to integrate third-party components such as antennas or cables into the system. These influencing factors are described in more detail in Sections Antennas (Page 185) and Antenna cables (Page 196).Antennas6.4 Guidelines for selecting RFID UHF antennasSIMATIC RF600182 System Manual, 06/2010, J31069-D0171-U001-A10-7618 Draft Version 02.06.2010

There are two different application cases:Antennas6.4 Guidelines for selecting RFID UHF antennasSIMATIC RF600System Manual, 06/2010, J31069-D0171-U001-A10-7618 183 Draft Version 02.06.2010
● Selection of third-party components:you wish to select appropriate third-party components for the SIMATIC RF600 system and to subsequently configure the reader for these components.● Configuration of existing third-party components:you already have third-party components (antenna, antenna cable or both) and wish to appropriately configure the reader for these components.Procedure for selecting third-party componentsAlways proceed in the following order during your considerations and the practical implementation:1. Consider which third-party components you wish to use in the SIMATIC RF600 system.2. Depending on the third-party component required, refer either to Section Antennas (Page 185) or Section Antenna cables (Page 196) for the important criteria for selection of your components. The selection criteria/parameters are sorted in descending relevance.3. Use the specified equations to calculate your missing parameters, and check whether the required values are reached (e.g. antenna gain) and that important secondary values (e.g. cable loss) are not exceeded or undershot.4. Configure the reader with the parameters of your third-party components. You can usually carry this out in the SIMATIC RF660R configuration software. The exact procedure is described in Section .5. For advanced users or in exceptional cases, e.g. input of an antenna gain <4.0 dBi), it is recommendable to carry out the configuration directly using XML commands. For further information, refer to Section .Procedure for configuration of existing third-party componentsIf you already have third-party components which you wish to integrate into the SIMATIC RF600 system, proceed as follows:1. Depending on the third-party component, refer either to Section "Antennas" or Section "Antenna cables" for the important criteria of your components. The parameters are sorted in descending relevance.2. Compare the limits with the data of your antenna or cable vendor.3. Subsequently proceed exactly as described above in "Procedure for selecting third-party components" from Paragraph 3. onwards.Antennas6.4 Guidelines for selecting RFID UHF antennasSIMATIC RF600184 System Manual, 06/2010, J31069-D0171-U001-A10-7618 Draft Version 02.06.2010
6.4.4 Antennas6.4.4.1 Types of antenna and properties Basically all types of directional antennas can be considered as third-party antennas for integration into the SIMATIC RF600 system. Directional antennas have a preferred direction in which more energy is radiated than in other directions. 6.4.4.2 Antenna parametersOverviewThe properties of an antenna are determined by a large number of parameters. You must be aware of these properties in order to make the correct selection for your appropriate UHF antenna. The most important parameters are described below. These important parameters are described in detail in the following sections. The following parameters describe both the send and receive functions of the antenna (reciprocity). The antenna is a passive antenna. A two-way relationship exists.● Radiated power● Antenna gain● Impedance● Return loss / VSWR● Power rating● Polarization● Front-to-back ratio● Beam widthRadiated powerIn order to comply with national directives with regard to the radiated power (which differ depending on the location or country of use), the RF660R reader together with the antenna cable(s) and antenna(s) must be exactly parameterized or configured.This means that the product of the transmitted power P0 of the reader and the antenna gain G must always have the correct ratio with regard to the radiated power "EIRP" depending on the location of use or the permissible frequency band.Calculation of the radiated power is briefly described below.Calculation of the radiated powerThe radiated power is the total power radiated by the antenna in the room. The isotropic radiator serves as the physical computing model which uniformly radiates the power into the room (spherically). Antennas6.4 Guidelines for selecting RFID UHF antennasSIMATIC RF600System Manual, 06/2010, J31069-D0171-U001-A10-7618 185 Draft Version 02.06.2010
EIRPDirectional antennas combine the radiation, and therefore have a higher power density in the main beam direction compared to an isotropic radiator. To enable antennas of different design or Directional characteristic to be compared with one another, the equivalent isotropic radiated power (EIRP) has been introduced which represents the effective power which must be applied to an isotropic radiator in order to deliver the same power density in the main beam direction of the antenna. EIRP is the product of the transmitted power P0 and the antenna gain G:EIRP = P0 * GERPAlso common is specification of the equivalent radiated power referred to the half-wave dipole "ERP" (effective radiated power):Logarithmic and standardized dataApproximate calculations are easier to carry out as additions than as products, therefore the logarithms are taken for the above equations and the power data standardized to 1 mW and specified in decibels (dBm or dBi).Calculation of the radiated power with consideration of the cable loss akIf the transmitted power is not applied directly but via a cable with loss aK, this loss should be compensated such that the same radiated power is obtained.If the loss is not appropriately compensated, the radiated power is too small.General preliminary information on the unit "dB"RequirementsThis section provides you with information on the unit "decibel". This knowledge is a requirement for optimum understanding of the following section. You can ignore this section if you already have the appropriate knowledge.Antennas6.4 Guidelines for selecting RFID UHF antennasSIMATIC RF600186 System Manual, 06/2010, J31069-D0171-U001-A10-7618 Draft Version 02.06.2010
DefinitionWhen specifying decibels, the ratios between powers or voltages are not defined directly but as logarithms. The decibel is therefore not a true unit but rather the information that the specified numerical value is the decimal logarithm of a ratio of two power or energy variables P1 and P2 of the same type.This ratio is defined by the following equation:Example:If P1 = 200 W and P2 = 100 mW, how large is the ratio a in dB?Use with other unitsAs with other units, there are also different versions of the unit for decibel depending on the reference variable. With this reference, the logarithmic power ratio becomes an absolute variable. The following table lists the most important combinations in this context with other units:Versions of decibel Description0 dBm Power level with the reference variable 1 mW.dBi Power level with the reference variable on the isotropic spherical radiator (see also Section Antenna gain (Page 187) ).Antenna gainDefinitionThe antenna gain specifies the degree to which the antenna outputs or receives its power in the preferred angle segment. With this theoretical variable, a comparison is always made with an isotropic spherical radiator, a loss-free antenna which does not exist in reality. It describes how much power has to be added to the isotropic spherical radiator so that it outputs the same radiated power in the preferred direction like the antenna to be considered. The unit for the antenna gain is therefore specified in dBi (dB isotropic). Antennas6.4 Guidelines for selecting RFID UHF antennasSIMATIC RF600System Manual, 06/2010, J31069-D0171-U001-A10-7618 187 Draft Version 02.06.2010
The antenna gain is defined for the receive case as the ratio between the power received in the main beam direction and the received power of the isotropic spherical radiator.SpecificationsYou must know the antenna gain in the corresponding frequency band or range. You can obtain the value of the antenna gain from the technical specifications of your antenna vendor.● With a cable loss of 4 dB, a gain ≥ 6 dBi(L) is required since otherwise the maximum radiated power will not be achieved.● In the case of antennas used in the FCC area of approval, a gain of at least 6 dBi(L) is required since otherwise the permissible radiated power of 4 W EIRP will not be reached.● If the gain is > 6 dBi(L)*, the difference is compensated in accordance with the directives by reducing the transmitted power.* (L) is the reference to the linear polarization.Dependencies● Frequency dependency:if a frequency dependency exists in the frequency band used, you must apply the highest value in each case for the antenna gain. With the cable loss, on the other hand, you must select the smallest value in each case it frequency dependency exists. This procedure means that the permissible radiated power will not be exceeded in the extreme case.● Dependency on the planeIf the data for the antenna gain are different in the horizontal and vertical planes, you must use the higher value in each case.ImpedanceDefinitionImpedance is understood as the frequency-dependent resistance. The impedances of the antenna, reader and antenna cables should always be the same. Differences in the impedance result in mismatching which in turn means that part of the applied signal is reflected again and that the antenna is not fed with the optimum power.Specifications● Only antennas can be used whose connection has a characteristic impedance of Z = 50 Ohm.● The mechanical design of the coaxial antenna connection is of secondary importance; N, TNC and SMA plug connectors are usual.Antennas6.4 Guidelines for selecting RFID UHF antennasSIMATIC RF600188 System Manual, 06/2010, J31069-D0171-U001-A10-7618 Draft Version 02.06.2010
Return loss / VSWRDefinitionSince the impedance at the antenna connection is frequency-dependent, mismatching automatically occurs with broadband use. This mismatching can be reflected by two parameters:● The voltage standing wave ratio VSWR● The return lossVoltage standing wave ratio VSWRThe power sent by the transmitter cannot flow unhindered to the antenna and be radiated as a result of the mismatching described by the VSWR. Part of the power is reflected at the antenna and returns to the transmitter. The powers in the forward and reverse directions produce a standing wave which has a voltage maximum and a voltage minimum. The ratio between these two values is the VSWR (voltage standing wave ratio).Return lossThe return loss parameter is based on the reflection factor which describes the voltage ratio between the forward and reverse waves.SpecificationsSo that the smallest possible transmitted and received powers are reflected by the antenna under ideal conditions, you should observe the following data for the VSWR and the return loss |S11|/ dB in the respective frequency band (865-870 MHz or 902-928 MHz):● VSWR < 1.24:1 or●|S11|/ dB ≥ 20 dBPower ratingDefinitionThe power rating is understood as the maximum power defined by the vendor with which the device may be operated.SpecificationsThird-party antennas must be dimensioned for an effective power applied to the antenna connection of at least 4 Watt.Antennas6.4 Guidelines for selecting RFID UHF antennasSIMATIC RF600System Manual, 06/2010, J31069-D0171-U001-A10-7618 189 Draft Version 02.06.2010
PolarizationDefinitionThe polarization parameter describes how the electromagnetic wave is radiated by the antenna. A distinction is made between linear and circular polarization. With linear polarization, a further distinction is made between vertical and horizontal polarization.SpecificationsUHF transponders usually have a receive characteristic similar to that of a dipole antenna which is linearly polarized. Horizontal or vertical polarization is then present depending on the transponder mounting.Selection of circular polarized antennaIf the orientation of the transponder is unknown, or if an alternating orientation can be expected, the transmit and receive antennas must have circular polarization.When selecting a circular antenna, the polarization purity must be observed in addition to the polarization direction. A differentiation is made between left-hand and right-hand circular polarization (LHCP and RHCP). The two types cannot be combined in the same system. On the other hand, selection of the polarization direction is insignificant if the antenna system of a transponder is linearly polarized. With actual antennas, elliptical polarization is encountered rather than the ideal circular polarization. A measure of this is the ratio between the large and small main axes of the ellipse, the axial ratio (AR), which is frequently specified as a logarithm.Axial ratio ARIdeal 0 dBReal 2-3 dBAntennas6.4 Guidelines for selecting RFID UHF antennasSIMATIC RF600190 System Manual, 06/2010, J31069-D0171-U001-A10-7618 Draft Version 02.06.2010
Figure 6-18 Circular polarization of antenna system and transponderSelection of linear polarized antennaWhen using linear polarized antennas, you must always make sure that the transmitter antenna, receiver antenna and transponder have identical polarizations (vertical or horizontal).

As a result of the principle used, no special requirements need be observed to suppress the orthogonal components (cross-polarization).①Transmitter antenna, vertical polarization②Receiver antenna, vertical polarization③Transponder dipoleFigure 6-19 Homogenous vertical polarization of antenna system and transponder Front-to-back ratioDefinitionAs a result of their design, directional antennas not only transmit electromagnetic waves in the main beam direction but also in other directions, particularly in the reverse direction. The largest possible suppression of these spurious lobes is expected in order to reduce faults and to keep the influence on other radio fields low. This attenuation of spurious lobes in the opposite direction to the main beam is called the front-to-back ratio. SpecificationsRequirement: The front-to-back ratio must be ≥ 10 dB. This requirement also applies to spurious lobes illustrated by the following graphics in Section Half-value width (Page 193).Antennas6.4 Guidelines for selecting RFID UHF antennasSIMATIC RF600192 System Manual, 06/2010, J31069-D0171-U001-A10-7618 Draft Version 02.06.2010
Half-value widthDefinitionA further description of the directional characteristic is the beam width. The beam width is the beam angle at which half the power (-3 dB) is radiated referred to the maximum power. The antenna gain is directly related to the beam width. The higher the antenna gain, the smaller the beam angle. Coupling in ETSIIn ETSI EN 302 208 (release version V1.2.1 2008-06), the radiated power is coupled to the beam width, i.e.● Radiated power 500-2000 mW ERP: beam width ≤ 70 degreesThe beam width requirement applies to both the horizontal and vertical planes. The FCC directives do not envisage coupling with the beam width.The following graphics show examples of the directional radiation pattern of an antenna in polar and linear representations for which both the horizontal and vertical planes must be considered.Directional radiation pattern in polar representation①Beam width②Spurious lobeAntennas6.4 Guidelines for selecting RFID UHF antennasSIMATIC RF600System Manual, 06/2010, J31069-D0171-U001-A10-7618 193 Draft Version 02.06.2010
Directional radiation pattern in linear representation①Beam width②Spurious lobeSpecificationsSelection of the beam angle within the approval directives also has effects on the field of application, since a larger beam angle allows a larger area to be covered by RFID Antennas6.4 Guidelines for selecting RFID UHF antennasSIMATIC RF600194 System Manual, 06/2010, J31069-D0171-U001-A10-7618 Draft Version 02.06.2010
transponders. The following graphic clarifies the cross-section of the beam cone with the covered area. Beam angle: cross-section of the beam cone with the covered area①Third-party antenna②Beam angle③Covered area④Activation or reading rangeThe reading range depends on the horizontal and vertical beam widths in the case of equal distances from the transmitter antenna. Depending on the mechanical mounting and the ratio between the vertical beam width ① and the horizontal beam width ②, read areas result as shown in the following graphic: Antennas6.4 Guidelines for selecting RFID UHF antennasSIMATIC RF600System Manual, 06/2010, J31069-D0171-U001-A10-7618 195 Draft Version 02.06.2010
Read area depending on the beam width①Vertical beam width②Horizontal beam width6.4.5 Antenna cables6.4.5.1 Selection criteria You must observe the criteria listed below when selecting the appropriate antenna cable for your third-party antenna.Characteristic impedanceDefinitionIf the input impedance of a device does not agree with the cable impedance, reflections occur which reduce the power transmission and can result in the appearance of resonance and thus to a non-linear frequency response.Specifications● You must only use coaxial antenna cables when connecting a third-party antenna.● This antenna cable must have a nominal characteristic impedance of Z = 50 Ohm.Antenna cable lossIn order to be able to transmit the available UHF power from the SIMATIC RF660R reader to the antenna(s), the antenna cable loss must not exceed a value of approx. 4 dB.Antennas6.4 Guidelines for selecting RFID UHF antennasSIMATIC RF600196 System Manual, 06/2010, J31069-D0171-U001-A10-7618 Draft Version 02.06.2010
Dependency of the cable lossThe cable loss depends on two important factors:● External characteristics of cable. These includes the cable length, diameter and design.● As a result of the physical principle, the cable loss is also frequency-dependent, i.e. the cable loss increases at higher transmitter frequencies. Therefore the cable loss must be specified in the frequency band from 860 to 960 MHz.Cable vendors usually provide tables or calculation aids for their types of cable which usually include the transmitter and receiver frequencies as well as the cable length. Therefore contact your cable vendor in order to determine the appropriate type of cable using the approximate value referred to above. 6.4.5.2 Notes on useShielding of the antenna cableCoaxial antenna cables always have a shielded design and therefore radiate little of the transmitted power to the environment. NoteCable with double shieldingYou should therefore preferentially select cable with double shielding since this provides the best damping. Bending radius of the antenna cableThe properties of the cable shield are influenced by mechanical loading or bending. You must therefore observe the static and dynamic bending radii specified by the cable vendor.Connectors and adaptersYou must use connectors and adapters of type "Reverse Polarity R-TNC" (male connector) for your antenna cables from a third-party supplier in order to guarantee correct connection to the SIMATIC RF660R reader.The figure below shows the standard for a suitable thread:You can find more information in the catalog data of your cable vendor.Antennas6.4 Guidelines for selecting RFID UHF antennasSIMATIC RF600System Manual, 06/2010, J31069-D0171-U001-A10-7618 197 Draft Version 02.06.2010
