Safety Information 2.3 Safety distance to transmitter antenna SIMATIC RF600 System Manual, 05/2012, J31069-D0171-U001-A13-7618 19 Note User responsibility for modified product As a user of the modified product, you accept responsibility for use of the complete RFID product comprising both SIMATIC RF600 components and third-party RFID components. This particularly applies to modification or replacement of: • Antennas • Antenna cables • readers • Power supply units with connection cables 2.3 Safety distance to transmitter antenna 2.3.1 Safety distance between transmitter antenna and personnel For 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. Limits The 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 0,073 400 - 2.000 1.375 x f1/2 0.0037 x f1/2 2.000 - 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/m Magnetic field strength: H = 0.111 A/m HF power density: E x H = 4.57 W/m2

For distances less than 1 λ in the near field, the electrical field strength (1/r) diminishes exponentially to the power three over distance, and for distances greater than 1 λ, it diminishes exponentially to the power two over distance. 01020304050607080901000,1 0,2 0,3 0,4 0,5 0,6 0,7 0.8 0.9 1(OHFWULFDOILHOGVWUHQJWKDWDGLVWDQFHIURPWKH7;DQWHQQDIRU3 :(53'LVWDQFHP)LHOGVWUHQJWK9P The horizontal line at 41.25V/m marks the "safety limit value". For the maximum permissible transmit power (1/r2) 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.

Safety Information 2.3 Safety distance to transmitter antenna SIMATIC RF600 System Manual, 05/2012, J31069-D0171-U001-A13-7618 21 Note Reduced maximum radiated power with RF620R/RF630R readers The 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 permissible radiated power in accordance with FCC (4W EIRP), the "safety distance" d = 0.26 m. This means that personnel should not remain closer than 26 cm to the transmitter antenna for extended periods (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. 0204060801001200.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1(OHFWULFDOILHOGVWUHQJWKDWDGLVWDQFHIURPWKH7;DQWHQQDIRU3 :(,53'LVWDQFHP)LHOGVWUHQJWK9P The horizontal line at 41.25 V/m marks the "safety limit value".

Note Reduced maximum radiated power with RF620R/RF630R readers The SIMATIC RF620R (FCC) reader has a maximum transmit power of 0.5 W. Thus the radiated power of 4 W EIRP cannot be exceeded with the internal antenna. The SIMATIC RF630R (FCC) reader has a maximum transmit 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 4 W EIRP.
SIMATIC RF600 System Manual, 05/2012, J31069-D0171-U001-A13-7618 23 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 readers (write/read devices), fitted for example on the gates of a warehouse, automatically record every movement of goods, and signal these to the higher-level 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 RF600 System Manual, 05/2012, J31069-D0171-U001-A13-7618 31 RF600 system planning 44.1 Overview You 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 Directives 4.2 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.

The objective is to provide the right material at the right time. This can be particularly useful in plants with frequently changing manufacturing scenarios for ensuring that incorrect infeed and downtimes are minimized. 6,0$7,&6FRQWUROOHU5)5 6,0$7,&5)&5)5 Features of the scenario The 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.

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. 6,0$7,&6FRQWUROOHU$60 Features of the scenario RFID 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.

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 production ● Order picking ● Packing 6,0$7,&6FRQWUROOHU+DQGKHOGWHUPLQDO5)0$605)5 Features of the scenario In 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.
RF600 system planning 4.2 Possible system configurations SIMATIC RF600 System Manual, 05/2012, J31069-D0171-U001-A13-7618 37 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. The SIMATIC RF680M mobile handheld terminal is used in this example for additional analysis and visualization of the item data directly on site.

The SIMATIC RF670R reader with its four antennas monitors the incoming goods gate of a factory building hall through which pallets are delivered. Each pallet is fitted with a tag. The tags contain user data that provides information about the sender and receiver of the goods. This data is read out and passed on. The goods supplied on the pallets are processed in the factory and then exit the factory through the outgoing goods gate. 8VHUDSSOLFDWLRQ/LJKWEDUULHU2XWJRLQJJRRGV,QFRPLQJJRRGVED\5)55)0$1$*(5%DVLF5)55)57DJ in this example, the SIMATIC RF640R reader is controlled by a light barrier and monitors a conveyor belt; the conveyor belt transports the goods towards two output gates that are assigned to different recipients. Each item has a tag that is always fitted at the same position and with the same alignment on the item. These tags also contain user data that provides information about the sender and receiver of the goods. There is a separator at the end of the conveyor belt that determines the output gate to which the goods should be directed. The separator is set according to the results from the reader and the goods are distributed.

These tags also contain user data that provides information about the sender and receiver of the goods. Based on the data read by the SIMATIC RF670R reader, the pallets at the outgoing goods gate are checked to make sure that they are intended for the receiver to which the gate is assigned. Light barriers are installed to control the reader. Depending on the read results of the reader, the outgoing portal opens, or it remains closed.

With the various configurations, please note that up to four external antennas can be connected to the RF670R reader, up to two can be connected to the RF630R reader and one external antenna can be connected to the RF640R or RF620R reader. The RF640R and RF620R readers also have an internal 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 Tag This antenna configuration is possible with the following readers: • RF670R with one antenna • RF640R with integrated or with external antenna • RF630R with one antenna • RF620R with integrated or with external antenna

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 Tag This antenna configuration is possible with the following readers: • RF670R with four antennas

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 range Maximum probability of identification of tags. Vertical tag alignment Minimal reading range Minimum probability of identification of tags. 4.3.4 Specified minimum and maximum spacing of antennas Specified minimum spacing of antennas The 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.

Otherwise the minimum spacing from the following section applies. The minimum spacing between antennas mounted alongside each other or one above the other depends on the transmit power of the reader and the sensing range of the transponders.

RF600 system planning 4.3 Antenna configurations SIMATIC RF600 48 System Manual, 05/2012, J31069-D0171-U001-A13-7618 4.3.5 Mutual interference of readers (antennas) Using more than one reader When several RFID readers are used, there is a danger that RFID tags can also be read by other readers. It must be ensured that the tag can only be identified by the appropriate reader. Technical disruptions between readers then occur particularly when they transmit on the same channel (on the same frequency). You will find more detailed information in the section "The response of electromagnetic waves in the UHF band (Page 72)". 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. Antenna alignment and antenna spacing with an external antenna The 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 RF660A = 2000 mW ERP; RF640R with RF660A = 2000 W ERP; RF620R/RF630R = 500 mW ERP) and the antenna alignment.

This means that the type of antenna cannot be freely selected. This means that the interference spacing in arrangement E is greater than in arrangement F (see section Auto-Hotspot). Note Rotation of the reader through 90° around the z axis Since the horizontal electrical aperture angle of the RF620R antenna is greater than the vertical aperture angle, the effects on adjacent readers can be reduced by using the reader as shown in arrangement F (see arrangements E and F in section Auto-Hotspot). With the SIMATIC RF660A antenna The electrical aperture 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. With the RF640A/RF642A antenna The electrical aperture angles (vertical and horizontal) of the RF640A/RF642A antenna are similar. Therefore, the robustness of the readers' access to transponder data can be optimized only to a limited extent by rotating around the antenna axis. Application example for RF620R/RF630R The following example illustrates measures for increasing the reliability of data access to transponders for readers with internal antennas: ● The antennas are placed next to each other and are aligned parallel to each other (see arrangement B in section Auto-Hotspot). ● The readers have been rotated through 90° around the z axis. The table below provides you with an overview of the minimum spacing to be maintained at a radiated power of 27 dBm with a maximum number of reachable transponders:

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 environment In 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. Number of transponders in the antenna field The typical ranges always relate to a transponder installed at the maximum possible distance from the antenna. If there is more than one transponder in the antenna field, the distance to all other transponders must be less to allow them to be acquired in the antenna field. The width and height of the antenna field within which its transponders can be arranged at a certain distance from the antenna depend on the following: • The radiated power, • Only reading or reading and writing the transponders (writing requires more power, typically double the power) • The aperture angle (horizontal) • The aperture angle (vertical) You will find detailed information about the reading range of the individual readers in the "Technical specifications" in the sections for the various readers.
RF600 system planning 4.3 Antenna configurations SIMATIC RF600 52 System Manual, 05/2012, J31069-D0171-U001-A13-7618 4.3.7 Static/dynamic mode Reading or writing can be either static or dynamic. ● Reading/writing is counted as being static if the tag does not move in front of the antenna and is read or written. ● Reading/writing is counted as being dynamic if the tag moves past the antenna during reading/writing. The following overview shows which environments are suitable for which read or write mode: Operating mode Read Write Static Recommended in normal UHF environments Recommended in normal UHF environments Dynamic Recommended under difficult UHF conditions Not recommended in difficult UHF environments 4.3.8 Operation of several readers within restricted space 4.3.8.1 Dense Reader Mode A special operating mode according to the standard EPC Global Class 1, Gen 2 in Dense Reader Mode allows several RF600 readers to be operated without interference in close proximity to each other. All RF600 readers operate in Dense Reader Mode according the standard EPC Global Class 1, Gen 2. Dense Reader Mode allows physically adjacent readers to use the same frequency when Gen 2 tags are being used. Special features for ETSI In accordance with EPC Global as well as ETSI EN 302 208 V1.3.1, the four transmit channels are used for transmission with the RF670R, with the RF640R as of firmware version V1.3, and with the RF620R/RF630R (see section Regulations for UHF frequency bands in Europe (Page 74)) 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. 4.3.8.2 Optimizing tag reading accuracy An improvement in the tag reading accuracy in an environment with a high density of readers can be achieved by aligning the antennas toward the relevant tag field, in other words by rotating them horizontally and vertically. In addition, the transmitter power of the readers can be reduced down to the minimum at which the tags are still just detected accurately.
RF600 system planning 4.3 Antenna configurations SIMATIC RF600 System Manual, 05/2012, J31069-D0171-U001-A13-7618 53 This greatly reduces the probability of interference. 4.3.8.3 Optimization of robustness of tag data accesses for readers that are operated simultaneously Parameter data access reliability If 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 section The response of electromagnetic waves in the UHF band (Page 72)) ● Type of transponder (see section Transponder/tags (Page 265)) ● Number of transponders to be detected by an antenna at a time ● Type of antenna (see section Antennas (Page 187), section Guidelines for selecting RFID UHF antennas (Page 54), and section Planning application (Page 99)) ● Transponders' distance from and orientation toward antennas (see section Transponder/tags (Page 265)) ● Distances and orientation of antennas of different readers to each other ● Radiated power of antennas The 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. 4.3.8.4 Frequency hopping This technique is intended to prevent mutual interference between readers. The reader changes its transmission channel in a random or programmed sequence (FHSS). Procedure for FCC Frequencyhopping is always active with FCC. The 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 81)). 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 76)).

According to ETSI EN 203 208 V1.2.1, Frequencyhoppingis advisable, however this is should preferably be multichannel operation with Frequencyhopping. Without Frequencyhopping, only single channel operation is possible for which the standard specifies a pause of 100 ms after each 4 s of sending. 4.3.9 Guidelines for selecting RFID UHF antennas 4.3.9.1 Note safety information WARNING Before planning how to use third-party components, as the operator of a system that comprises both RF600 components and third-party components, you must comply with the safety information in Section Safety instructions for third-party antennas as well as for modifications to the RF600 system (Page 18). 4.3.9.2 Preconditions for selecting RFID UHF antennas Target group This chapter has been prepared for configuration engineers who thoroughly understand and wish to carry out the selection and installation of an external antenna or an external cable for the SIMATIC RF600 system. 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 chapter This 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. 4.3.9.3 General application planning Overview of the total SIMATIC RF600 system and its influencing factors The following graphic shows the design of the total SIMATIC RF600 system and the factors which have an influence on the total system.

The device could be damaged if these factors are not considered.
RF600 system planning 4.3 Antenna configurations SIMATIC RF600 56 System Manual, 05/2012, J31069-D0171-U001-A13-7618 General procedure Depending on whether you want to use a third-party antenna or antenna cable (or both) in a combination with the RF600 system, these instructions will help you to select the components and to set the important parameters in the RF MANAGER Basic. There are two different application cases: ● 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 components Always 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 Auto-Hotspot or Section Auto-Hotspot 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. Normally, you can do this with the RF MANAGER Basic. Depending on the reader, the values can alternatively also be set via XML protocol or SIMATIC protocol. You will find an overview of the information for the parameter assignment of all RF600 system readers in the section Overview of parameterization of RF600 reader (Page 377). Procedure for configuration of existing third-party components If 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.

Directional antennas have a preferred direction in which more energy is radiated than in other directions. RF600 antennas on the other hand, are optimized for operation with RF600 readers and have all the required approvals. Antenna parameters Overview The 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 width Radiated power In order to comply with national directives with regard to the radiated power (which differ depending on the location or country of use), the RF600 readers 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 Gi 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 power The 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, i.e. isotropic).
RF600 system planning 4.3 Antenna configurations SIMATIC RF600 58 System Manual, 05/2012, J31069-D0171-U001-A13-7618 EIRP Directional 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 Gi: EIRP = P0 * Gi ERP Also common is specification of the equivalent radiated power referred to the half-wave dipole "ERP" (effective radiated power): *L3*G3(53 Logarithmic and standardized data Approximate 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). (53G%P3G%P G%G*G (,53G%P3G%P G%L*L 3G%P G%L*L 3G%P G%G*GG%DN Calculation of the radiated power with consideration of the cable loss ak If 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.   LILI(,53G%P3G%P*G%LDNG% DN!DN!(53G%P3G%P G%GDNG%*G3G%P G%LDNG%*L If the loss is not appropriately compensated, the radiated power is too small.

This knowledge is a requirement for optimum understanding of the following section. You can ignore this section if you already have the appropriate knowledge. Definition When 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: DORJ3G%3 Example If P1 = 200 W and P2 = 100 mW, how large is the ratio a in dB?  ORJG% ORJ G% D3G%3
RF600 system planning 4.3 Antenna configurations SIMATIC RF600 60 System Manual, 05/2012, J31069-D0171-U001-A13-7618 Use with other units As 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 Description 0 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 60) ). The relationship between dBi and dBic is as follows: dBi = dBic - 3 dBd Power level with the reference variable on the dipole radiator. The relationship between dBd and dBi is as follows: dBd = dBi - 2.15 dBic Power level with the reference variable on the isotropic radiator for circular antennas. The relationship between dBi and dBic is as follows: dBic = dBi + 3 Antenna gain Definition The 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). 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. Specifications You 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.
RF600 system planning 4.3 Antenna configurations SIMATIC RF600 System Manual, 05/2012, J31069-D0171-U001-A13-7618 61 * (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 plane If the data for the antenna gain are different in the horizontal and vertical planes, you must use the higher value in each case. Impedance Definition Impedance 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. Return loss / VSWR Definition Since 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 loss
RF600 system planning 4.3 Antenna configurations SIMATIC RF600 62 System Manual, 05/2012, J31069-D0171-U001-A13-7618 Voltage standing wave ratio VSWR The 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 loss The return loss parameter is based on the reflection factor which describes the voltage ratio between the forward and reverse waves. Specifications So 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 dB Power rating Definition The power rating is understood as the maximum power defined by the vendor with which the device may be operated. Specifications Third-party antennas must be dimensioned for an effective power applied to the antenna connection of at least 4 Watt. Polarization Definition The 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. Specifications UHF 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.
RF600 system planning 4.3 Antenna configurations SIMATIC RF600 System Manual, 05/2012, J31069-D0171-U001-A13-7618 63 Selection of circular polarized antenna If 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 AR Ideal 0 dB Real 2-3 dB  Figure 4-7 Circular polarization of antenna system and transponder
RF600 system planning 4.3 Antenna configurations SIMATIC RF600 64 System Manual, 05/2012, J31069-D0171-U001-A13-7618 Selection of linear polarized antenna When 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).  ① Transmitter antenna, vertical polarization ② Receiver antenna, vertical polarization ③ Transponder dipole Figure 4-8 Homogenous vertical polarization of antenna system and transponder Front-to-back ratio Definition As 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. Specifications Requirement: 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 65).
RF600 system planning 4.3 Antenna configurations SIMATIC RF600 System Manual, 05/2012, J31069-D0171-U001-A13-7618 65 Half-value width Definition A 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 ETSI In 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 degrees The 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.

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.

The dBr value -3 is shown graphically in both diagrams. At angles of Phi = ± 35°, the range of the antenna is only 50% of the maximum range. Specifications Selection 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 transponders.

Characteristic impedance Definition If 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 loss In order to be able to transmit the available UHF power from the RF600 reader to the antenna(s), the antenna cable loss must not exceed a value of approx. 4 dB.
RF600 system planning 4.3 Antenna configurations SIMATIC RF600 System Manual, 05/2012, J31069-D0171-U001-A13-7618 69 Dependency of the cable loss The 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. Notes on use Shielding of the antenna cable Coaxial antenna cables always have a shielded design and therefore radiate little of the transmitted power to the environment. Note Cable with double shielding You should therefore preferentially select cable with double shielding since this provides the best damping. Bending radius of the antenna cable The 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 adapters You 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 ensure correct connection to the RF600 reader interface. The figure below shows the standard for a suitable thread: 81() You can find more information in the catalog data of your cable vendor.

Using this example it is possible to understand how the complete selection procedure for antennas, cables, and adapters as well as the settings could be carried out on an RF600 system reader. In the example, it is assumed that you want to use your SIMATIC RF600 system with your third-party components in Germany (ETSI EN 302 208 V1.3.1). Procedure 1. Compare the technical specifications of your antenna with the values required by the SIMATIC RF600 system. Values Example antenna Required values OK? Frequency range 865 to 870 MHz 865 to 868 MHz OK Impedance 50 ohms 50 ohms OK VSWR <1,5 <1,24 Not OK Polarization Circular, right OK Antenna gain 8.5 dBi >6 dBi OK Half-value width horizontal/vertical 63° ≤70° OK Front-to-back ratio -18 dB ≥10 dB OK Spurious lobe suppression -16 dB ≥10 dB OK Axial ratio 2 dB ≤3 dB OK Maximum power 6 W ≥4 W OK Since the specific VSWR value of the antenna does not agree with the value required by the system, you must have this value checked. Therefore contact your antenna vendor or an EMC laboratory. 2. Compare the technical specifications of your cables and connectors with the values required by the system. For example, you can use cables of type "LMR-195" from the company "TIMES MICROWAVE SYSTEMS". Suitable cables have e.g. an outer diameter of 5 mm. The company offers various designs of cables depending on the requirements. Numerous connectors are also available for their cables. Values Example cable Required values OK? Cable attenuation 36.5 dB / 100 m at 900 MHz With an assumed length of 10 m, this results in a loss of 3.65 dB. ≤4 dB OK Impedance 50 ohms 50 ohms OK Values Example connector OK?

Set the following parameter values depending on the reader you are using: – Assigning parameters for the RF640R/RF670R using the RF-MANAGER Basic V2 Antenna gain: 8.5 dBi Cable loss: 4 dB (due to adaptation and damping losses of the connectors) – Set parameters for the RF640R/RF670R using the XML command "setAntennaConfig" In the XML command "setAntenneConfig", the following must be set for the antenna port being used: (antenna number="1 ... 4"), antenna gain (gain="8.5") and cable loss (cableLoss="4.0"). Cable loss: 4 dB (due to adaptation and damping losses of the connectors) – Setting parameters for RF620R/RF630R using SIMATIC commands Since according to ETSI EN 302 208 V1.3.1 the maximum permissible radiated power is 2 W ERP, none of the transmit power settings available to the user (distance_limiting) can cause the required maximum permitted radiated power value to be exceeded. The exact radiated power of the reader, together with the antenna cables and antenna used, results from the value used in distance_limiting 0-F and the calculation in the section "Antenna parameters". 4. You must subsequently have your desired system requirements measured and verified according to EN 302 308 in an absorber chamber. You may only use your SIMATIC RF600 system with the new third-party components when this has been carried out. 4.4 Environmental conditions for transponders/tags Basic rules The 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.
RF600 system planning 4.5 The response of electromagnetic waves in the UHF band SIMATIC RF600 72 System Manual, 05/2012, J31069-D0171-U001-A13-7618 4.5 The response of electromagnetic waves in the UHF band 4.5.1 The effect of reflections and interference Reflections and interference Electromagnetic 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, 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 metals Metal 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.
RF600 system planning 4.5 The response of electromagnetic waves in the UHF band SIMATIC RF600 System Manual, 05/2012, J31069-D0171-U001-A13-7618 73 Tags mounted directly onto metal In 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 Auto-Hotspot and SectionAuto-Hotspot . 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 substances Non-metallic substances can also affect the propagation of electromagnetic waves. 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 components The 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 interference On 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 band On 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.

NOTICE Failure 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. 4.7.2 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 edges The 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.
RF600 system planning 4.7 Guidelines for electromagnetic compatibility (EMC) SIMATIC RF600 System Manual, 05/2012, J31069-D0171-U001-A13-7618 83 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 environment All 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. Note The 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. 4.7.3 Basic rules It 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.

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. ● 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.

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: ● 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 sources In 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.

All switched inductances are frequent sources of interference in plants.
RF600 system planning 4.7 Guidelines for electromagnetic compatibility (EMC) SIMATIC RF600 88 System Manual, 05/2012, J31069-D0171-U001-A13-7618 Suppression of inductance Relays, 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. 9DOYHV%UDNHV5HOD\FRLOV&RQWDFWRUV Figure 4-11 Suppression of inductance Note All 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. 4.7.6 Equipotential bonding Potential 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).

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. 4.7.7 Cable shielding Signal 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. Note An unconnected or incorrectly connected shield has no shielding effect.

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. 5HPRYHSDLQW&DEOHWLH Figure 4-14 Connection of shielding bus The shielding bus must be connected to the PE busbar.

The LED can be lit in green, red or yellow. The meaning of the indication changes in accordance with the color and state (on, off, flashing) of the LED: Green LED Red LED Yellow LED Meaning Off Off Off The device is starting up. Flashing Off Off The device is ready. The antenna is switched off. On Off Off The device is ready. The antenna is switched on. Off Off On "With presence": At least one tag is in the field. "Without presence": Communication with a tag is active. Off Flashing Off Reader is not active, a serious error has occurred. In addition, this LED also indicates the fault status through the number of flashing pulses. Reboot (operating voltage Off → On is necessary). The LED flashes once for the 'INACTIVE' status, rebooting is not necessary in this case. For more detailed information on the flash codes of the reader see section Error messages and flash codes for RF620R/RF630R (Page 386) Note LED not lit yellow? If the LED does not light up yellow even though a tag is located within the field, common causes are: • Incorrect configuration in the init_run command, or init_run command was not executed (see "Configuration Manual RF620R/RF630R") • Parameter assignment is incorrect (black list, RSSI threshold) • Antenna is switched off • A tag is used, that is not compatible with the reader protocol (EPC Global Class 1 Gen 2).• Tag is defective • Reader or antenna has a defect • Tag is not in the field of radiation of the transmit antenna
