The notices referring to your personal safety are highlighted in the manual by a safety alert symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are graded according to the degree of danger. DANGER indicates that death or severe personal injury will result if proper precautions are not taken. WARNING indicates that death or severe personal injury may result if proper precautions are not taken. CAUTION with a safety alert symbol, indicates that minor personal injury can result if proper precautions are not taken. CAUTION without a safety alert symbol, indicates that property damage can result if proper precautions are not taken. NOTICE indicates that an unintended result or situation can occur if the corresponding information is not taken into account. If more than one degree of danger is present, the warning notice representing the highest degree of danger will be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to property damage.

Conventions The RF310R, RF340R and RF380R readers are equipped with an integral antenna, whereas the RF350R reader is operated over an external antenna. In this system manual, the term "Reader" is used throughout even where it is actually referring to the antenna of the reader. 3.2.3 Application areas of RF300 SIMATIC RF300 is primarily used for non-contact identification of containers, palettes and workpiece holders in a closed production circuit. The data carriers (transponders) remain in the production chain and are not supplied with the products. SIMATIC RF300, with its compact transponder and reader enclosure dimensions, is particularly suitable in confined spaces. Main applications â Mechanical engineering, automation systems, conveyor systems â Ancillary assembly lines in the automotive industry, component suppliers â Small assembly lines 20 SIMATIC RF300 System Manual, 11/2009 - Zwischenstand 17.09.2009, A5E01642529-04 System overview 3.3 System configuration Application examples â Production lines for engines, gearboxes, axles, etc. â Assembly lines for ABS systems, airbags, brake systems, doors, cockpits, etc. â Assembly lines for household electrical appliances, consumer electronics and electronic communication equipment â Assembly lines for PCs, small-power motors, contactors, switches Advantages â Reading and writing of large data volumes within a short time results in shorter production cycle times and thus help to boost productivity â Can be used in harsh environments thanks to rugged components with high degree of protection â Simple and low-cost system integration into SIMATIC S7 and PROFIBUS (TIA) â Shorter commissioning times and fewer plant failures and downtimes thanks to integral diagnostic functionalities â Cost savings thanks to maintenance-free components 3.3 System configuration 3.3.1 Overview The SIMATIC RF300 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 RF300 system with its flexible components offers many possibilities for system configuration. This chapter shows you how you can use the RF300 components on the basis of various example scenarios. 3.3.2 Assembly line example: Use of RF300 tags In assembly lines, such as in engine manufacturing, many work steps are completed in succession. Automated or manual assembly work is carried out at the individual workstations in relatively short periods of time. The special features of the RF300 tags, which stand out for their large data memory and high transmission speeds, bring about many advantages in regard to the production unit numbers of such plants. The possibility of saving large volumes of data means savings in terms of data management on the HOST system and considerably contributes to data security. (redundant data management, e.g. HOST database, or controller and data carrier) Advantages at a glance: SIMATIC RF300 System Manual, 11/2009 - Zwischenstand 17.09.2009, A5E01642529-04 21 System overview 3.3 System configuration â Redundant data storage on the basis of large memory, availability of decentralized data â High data rate â Data management savings on the host system Characteristics of the scenario In this example scenario, engine blocks that are placed on metal pallets are conveyed on an assembly line. The engines are assembled piece-by-piece at the individual workstations. The SIMATIC RF340T RFID tag is securely affixed on the underside of the pallet. The transport speed is approx. 0.5 m/s. In this scenario, it is an advantage that the tag can be directly secured to metal on the metal pallets. The small-dimensioned SIMATIC RF310R reader is integrated in the conveyor elements in such a manner that it can communicate with the tags from below. Thus, it is not necessary to align the pallets or to attach several tags. The data of the entire production order (5000 bytes) is stored on the tag. This data is read at each workstation and changed or supplemented depending on the workstation, and then written back again. Thus, the status of the engine block assembly can be determined at any point in time, even if there is a failure at the HOST level. Thanks to the extremely high data rate, a very short cycle time for the work steps can be factored in, which results in high end product unit numbers (engines). The entire production order that is saved on the tag can also be manually read via the WINLC terminal located at each workstation. This means that virtually no additional data management is required on the control PC. The production order data can also be read for servicing purposes via the mobile SIMATIC RF310M handheld terminal. 22 SIMATIC RF300 System Manual, 11/2009 - Zwischenstand 17.09.2009, A5E01642529-04 System overview 3.3 System configuration 6,0$7,&6 FRQWUROOHU $60 (QJLQHEORFN 0HWDOSDOOHW +DQGKHOG WHUPLQDO 5)0 5)7 5)5 Figure 3-3 Example of engine block production 3.3.3 Example of container and paper board container handling: Use of ISO tags Containers of varying sizes are conveyed to picking workstations in a delivery center. There, the individual goods are removed and packed in cartons according to the delivery note. These cartons are marked with low-cost transponder labels and sorted to small or large packaging workstations (according to the delivery note) by being guided or transported via the corresponding conveyor system. The containers are marked using the MDS D100 ISO tag. Advantages at a glance: â Decision points in the conveyor system can be installed in a more favorable way (mechanically) â Different sizes of containers with different depths can be identified due to the range SIMATIC RF300 System Manual, 11/2009 - Zwischenstand 17.09.2009, A5E01642529-04 23 System overview 3.3 System configuration â In contrast to bar codes, tags can also be written to â Different types of tags can be processed using one and the same reader Characteristics of the scenario In this example scenario, containers of varying sizes are conveyed on a conveyor system. Only the unique identification number (8 bytes) is read. The containers to be picked are sorted to the corresponding workstations. The maximum transport speed is 1.0 m/s. In this scenario, it is an advantage that the RF380R reader can read and write the tags at different distances on the containers without a great deal of mechanical or control system effort due to the reading range. During the picking process, the goods are immediately placed in different containers or packed in cartons depending on the destination (small packaging or large packaging station). The containers are equipped with the MDS D100 ISO tag. The low-cost "one-way tag" (label) is used on the cartons: it is simply glued onto the carton. Thus the goods can be identified at any time. Again, one and the same reader is used for this. The maximum transport speed is 0.8 m/s. In addition, flexible identification is possible at each location and at any time using the mobile SIMATIC RF310M handheld terminal. 24 SIMATIC RF300 System Manual, 11/2009 - Zwischenstand 17.09.2009, A5E01642529-04 System overview 3.4 System data 6,0$7,&6 FRQWUROOHU $60 0'6' +DQGKHOGWHUPLQDO 5)0 Figure 3-4 3.4 5)5UHDGHU Example of container and paper board container handling System data Type Inductive identification system for industrial applications Transmission frequency data/energy 13.56 MHz Memory capacity ďˇ ďˇ Memory type EEPROM / FRAM Write cycles ďˇ ďˇ 20 bytes to 64 KB user memory (r/w) 4 bytes fixed code as serial number (ro) EEPROM: > 200 000 FRAM: Unlimited SIMATIC RF300 System Manual, 11/2009 - Zwischenstand 17.09.2009, A5E01642529-04 25 System overview 3.4 System data Read cycles Unlimited Data management Byte-by-byte access Data transmission rate Transponder reader Read RF300 tags ISO tags 8000 byte/s approx. 600 byte/s approx. 8000 byte/s approx. 400 byte/s (maximum values) Write (maximum values) Read/write distance RF300 tags: up to 0.15 m ISO tags: up to 0.2 m (system limit; depends on reader and transponder) ďˇ ďˇ Operating temperature Readers: -25°C to +70°C Transponder: -40 to +125 °C +220 °C cyclically Degree of protection Reader: IP 67 2) Transponder: > IP 67 Can be connected to ďˇ ďˇ ďˇ ďˇ ďˇ SIMATIC S7-300 PROFIBUS DP V1 PROFINET PC 1) Third-party control 1) Special features ďˇ ďˇ ďˇ ďˇ ďˇ ďˇ Very high data transfer rate High noise immunity Compact components Extensive diagnostic options A reader with IQ-Sense interface ISO 15693 functionality can be parameterized Approvals ďˇ ďˇ ďˇ ďˇ ETS 300 330 (Europe) FCC Part 15 (USA), UL/CSA CE, operating license for Japan 1) 2) 26 By means of RS422 interface and 3964R protocol Exception RF350R: IP 65 SIMATIC RF300 System Manual, 11/2009 - Zwischenstand 17.09.2009, A5E01642529-04 RF300 system planning 4.1 Fundamentals of application planning 4.1.1 Selection criteria for SIMATIC RF300 components Assess your application according to the following criteria, in order to choose the right SIMATIC RF300 components: â Transmission distance (read/write distance) â Tracking tolerances â Static or dynamic data transfer â Data volume to be transferred â Speed in case of dynamic transfer â Metal-free rooms for transponders and readers â Ambient conditions such as relative humidity, temperature, chemical impacts, etc. 4.1.2 Transmission window and read/write distance The reader generates an inductive alternating field. The field is strongest near to the reader. The strength of the field decreases in proportion to the distance from the reader. The distribution of the field depends on the structure and geometry of the antennas in the reader and transponder. A prerequisite for the function of the transponder is a minimum field strength at the transponder achieved at a distance Sg from the reader or the ANT1. The picture below shows the transmission window between transponder and reader or ANT1: SIMATIC RF300 System Manual, 11/2009 - Zwischenstand 17.09.2009, A5E01642529-04 27 RF300 system planning 4.1 Fundamentals of application planning Table 4- 1 RF310R reader and ANT 1 (RF350R) transmission window and read/write distance 6LGHYLHZ /' 6D 6J 7UDQVSRQGHU 63 3ODQYLHZ 6,(0(16 6,0$7,& 5)7 5)7 7UDQVSRQGHU / 6DPD[ /G / 6DPLQ /PD[ 7UDQVPLVVLRQZLQGRZ Sa: Operating distance between transponder and reader Sg Limit distance (maximum clear distance between upper surface of the reader and the transponder, at which the transmission can still function under normal conditions) Length of a transmission window The length Ld is valid for the calculation.

SIMATIC RF300 System Manual, 11/2009 - Zwischenstand 17.09.2009, A5E01642529-04 31 RF300 system planning 4.1 Fundamentals of application planning From the diagrams above, it can also be seen that operation is possible within the area between Sa and Sg. The active operating area reduces as the distance increases, and shrinks to a single point at distance Sg. Only static mode should thus be used in the area between Sa and Sg. 4.1.3 Width of the transmission window Determining the width of the transmission window The following approximation formula can be used for practical applications: % y/ B: Width of the transmission window L: Length of the transmission window Tracking tolerances The width of the transmission window (B) is particularly important for the mechanical tracking tolerance. The formula for the dwell time is valid without restriction when B is observed. 4.1.4 Impact of secondary fields Secondary fields in the range from 0 to 20 mm always exist. They should only be applied during planning in exceptional cases, however, since the read/write distances are very limited. Exact details of the secondary field geometry cannot be given, since these values depend heavily on the operating distance and the application. 32 SIMATIC RF300 System Manual, 11/2009 - Zwischenstand 17.09.2009, A5E01642529-04 RF300 system planning 4.1 Fundamentals of application planning Secondary fields without shielding &RQYH\LQJGLUHFWLRQ 7DJ 7DJ 6HFRQGDU\ ILHOG 5HDGHU &RQYH\LQJGLUHFWLRQ The following graphic shows typical primary and secondary fields, if no shielding measures are taken. 0DLQILHOG 7DJ Figure 4-1 Secondary field without shielding In this arrangement, the reader can also read tags via the secondary field.

The reader can exchange data with the transponder during this time. The dwell time is calculated thus: tv = L â 0,8 [ m] v [ m / s] Tag tV: Dwell time of the transponder L: Length of the transmission window vTag: Speed of the transponder (tag) in dynamic mode 0,8: Constant factor used to compensate for temperature impacts and production tolerances The dwell time can be of any duration in static mode. The dwell time must be sufficiently long to allow communication with the transponder. The dwell time is defined by the system environment in dynamic mode. The volume of data to be transferred must be matched to the dwell time or vice versa.

Depending on the communication module (ASM) used, transfer rates of 19200 baud, 57600 baud or 115200 baud can be selected. Calculation of the communication time for interference-free transfer The communication time for fault-free data transfer is calculated as follows: tK = K + tByte â n (n >1) If the transmission is interrupted briefly due to external interference, the communication module automatically continues the command.

It facilitates the correct selection of a transponder and reader. All the technical specifications listed are typical data and are applicable for an ambient temperature of between 0 C and +50 °C, a supply voltage of between 22 V and 27 V DC and a metal-free environment. Tolerances of Âą20 % are admissible due to production or temperature conditions. If the entire voltage range at the reader of 20 V DC to 30 V DC and/or the entire temperature range of transponders and readers is used, the field data are subject to further tolerances.

For this, values from approx. 0.5 W to approx. 2.0 W can be set in 0.25 W increments. Depending on the setting, the change to the transmission output power increases the performance in the lower operating distance (low performance) or in the upper limit distance (high performance). The "dili" value range goes from 02 (= 0.5 W) and 05 (default value: 1.25 W) to 08 (= 2 W). Note A dili value setting outside of the value range of 02 to 08 leads to the default setting (05) and does not generate an error message.

In this case, the data transfer time would increase unpredictably or a command would be aborted with an error. Adherence to the values specified in the "Minimum distance from reader to reader" table is therefore essential. If the specified minimum distance cannot be complied with due to the physical configuration, the SET-ANT command can be used to activate and deactivate the HF field of the reader. The application software must be used to ensure that only one reader is active (antenna is switched on) at a time.

Any type of metal, in particular iron and ferromagnetic materials, in the vicinity of these devices will affect their operation. Some points need to be considered during planning and installation if the values described in the "Field data" section are to retain their validity: â Minimum spacing between two readers or their antennas â Minimum distance between two adjacent data memories â Metal-free area for flush-mounting of readers or their antennas and transponders in metal â Mounting of multiple readers or their antennas on metal frames or racks The following sections describe the impact on the operation of the identification system when mounted in the vicinity of metal. 62 SIMATIC RF300 System Manual, 11/2009 - Zwischenstand 17.09.2009, A5E01642529-04 RF300 system planning 4.5 Installation guidelines 4.5.2 Reduction of interference due to metal Interference due to metal rack 0HWDOUDFN Problem 1RQPHWDOOLFVSDFHU A metal rack is located above the transmission window of the reader. This affects the entire field. In particular, the transmission window between reader and transponder is reduced. 6KHHW 7UDQVSRQGHU 6D 5HDGHUV 0HWDO Remedy: 7UDQVSRQGHU The transmission window is no longer affected if the transponder is mounted differently. 5HDGHU SIMATIC RF300 System Manual, 11/2009 - Zwischenstand 17.09.2009, A5E01642529-04 63 RF300 system planning 4.5 Installation guidelines Flush-mounting Flush-mounting of transponders and readers Problem 1RQPHWDOOLFVSDFHU Flush-mounting of transponders and readers is possible in principle. However, the size of the transmission window is significantly reduced. The following measures can be used to counteract the reduction of the window: 6KHHW 0HWDO 5HDGHUV 0HWDO Remedy: Enlargement of the non-metallic spacer below the transponder and/or reader. The transponder and/or reader are 10 to 20 mm higher than the metal surround. [!PP PP 5HDGHU (The value x ⼠100 mm is valid, e.g. for RF310R. It indicates that, for a distance x ⼠100 mm, the reader can no longer be significantly affected by metal.) Remedy: Increase the non-metallic distance a, b. The following rule of thumb can be used: ďˇ Increase a, b by a factor of 2 to 3 over the values specified for metal-free areas ďˇ Increasing a, b has a greater effect for readers or transponders with a large limit distance than for readers or transponders with a small limit distance. 5HDGHU Mounting of several readers on metal frames or racks Any reader mounted on metal couples part of the field to the metal frame. There is normally no interaction as long as the minimum distance D and metal-free areas a, b are maintained. However, interaction may take place if an iron frame is positioned unfavorably. Longer data transfer times or sporadic error messages at the communication module are the result. 64 SIMATIC RF300 System Manual, 11/2009 - Zwischenstand 17.09.2009, A5E01642529-04 RF300 system planning 4.5 Installation guidelines Mounting of several readers on metal racks Problem: Interaction between readers Remedy Increase the distance D between the two readers. 5HDGHU 5HDGHU Remedy Introduce one or more iron struts in order to shortcircuit the stray fields. 5HDGHU 5HDGHU Remedy 1RQPHWDOOLF VSDFHU 5HDGHU 4.5.3 Insert a non-metallic spacer of 20 to 40 millimeter thickness between the reader and the iron frame. This will significantly reduce the induction of stray fields on the rack: 5HDGHU Effects of metal on different transponders and readers Mounting different transponders and readers on metal or flush-mounting Certain conditions have to be observed when mounting the transponders and readers on metal or flush-mounting. For more information, please refer to the descriptions of the individual transponders and readers in the relevant section.

The metal rail would affect the field data. The impact of metal on the field data (Sg, Sa, L, B) is shown in tabular format in this section. The values in the table describe the reduction of the field data in % with reference to nonmetal (100% means no impact). 4.5.4.2 RF310R RF300 mode Table 4- 22 Reduction of field data by metal (in %): Transponder and RF310R Transponder RF320T RF340T RF350T RF360T 66 RF310R reader Without metal On metal Flush-mounted In metal (20 mm all around) Without metal 100 95 80 On metal;

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: â Higher component density â More switched power electronics â Increasing switching rates â 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. EMC can be broken down into three different areas: â Intrinsic immunity to interference: immunity to internal electrical disturbance â Immunity to external interference: immunity to external electromagnetic disturbance â 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. SIMATIC RF300 System Manual, 11/2009 - Zwischenstand 17.09.2009, A5E01642529-04 87 RF300 system planning 4.7 EMC Directives 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 â 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. â Use metal plates to shield against electromagnetic fields generated by inductances. â Use metal connector housings to shield data conductors. Wide-area ground connection â Bond all passive metal parts to chassis ground, ensuring large-area and low-HFimpedance contact. â Establish a large-area connection between the passive metal parts and the central grounding point. â 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. â Aluminium parts are not suitable for ground connections. Plan the cable installation â Break the cabling down into cable groups and install these separately. â Always route power cables, signal cables and HF cables through separated ducts or in separate bundles. â Feed the cabling into the cabinet from one side only and, if possible, on one level only. â Route the signal cables as close as possible to chassis surfaces. â Twist the feed and return conductors of separately installed cables. 88 SIMATIC RF300 System Manual, 11/2009 - Zwischenstand 17.09.2009, A5E01642529-04 RF300 system planning 4.7 EMC Directives â Routing HF cables: avoid parallel routing of HF cables. â Do not route cables through the antenna field. Shielding for the cables â Shield the data cables and connect the shield at both ends. â Shield the analog cables and connect the shield at one end, e.g. on the drive unit. â Always apply large-area connections between the cable shields and the shielding bus at the cabinet inlet and make the contact with clamps. â Feed the connected shield through to the module without interruption. â Use braided shields, not foil shields. Line and signal filter â Use only line filters with metal housings â Connect the filter housing to the cabinet chassis using a large-area low-HF-impedance connection. â Never fix the filter housing to a painted surface. â Fix the filter at the control cabinet inlet or in the direction of the source. 4.7.4 Propagation of electromagnetic interference Three components have to be present for interference to occur in a system: â Interference source â Coupling path â Interference sink ,QWHUIHUHQFHVRXUFH GHYLFHHPLWWLQJ LQWHUIHUHQFH HJGULYHXQLW Figure 4-22 &RXSOLQJSDWK HJFRQQHFWLQJFDEOH ,QWHUIHUHQFHVLQN GHYLFHDIIHFWHGE\ LQWHUIHUHQFH HJUHDGHU Propagation of interference If 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: SIMATIC RF300 System Manual, 11/2009 - Zwischenstand 17.09.2009, A5E01642529-04 89 RF300 system planning 4.7 EMC Directives â Only devices fulfilling limit class A of VDE 0871 may be used in a plant. â Interference suppression measures must be introduced on all interference-emitting devices. This includes all coils and windings. â 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. Table 4- 39 Interference sources: origin and effect Interference source Interference results from Effect on the interference sink Contactors, electronic valves Contacts System disturbances Coils Magnetic field Electrical motor Collector Electrical field Winding Magnetic field Contacts Electrical field Transformer Magnetic field, system disturbance, transient currents Power supply unit, switchedmode Circuit Electrical and magnetic field, system disturbance High-frequency appliances Circuit Electromagnetic field Transmitter (e.g. service radio) Antenna Electromagnetic field Electric welding device Ground or reference potential Voltage difference difference Transient currents Operator Static charge Electrical discharge currents, electrical field Power cable Current flow Electrical and magnetic field, system disturbance High-voltage cable Voltage difference Electrical field Cause Remedy What interference can affect RFID?

Note For information about electromagnetically compatible cabinet configuration, please consult the installation guidelines for SIMATIC PLCs. Shielding by enclosure Magnetic and electrical fields and electromagnetic waves can be kept away from the interference sink by using a metal enclosure. The easier the induced interference current can flow, the greater the intrinsic weakening of the interference field. All enclosures and metal panels in the cabinet should therefore be connected in a manner allowing good conductance. Figure 4-24 92 Shielding by enclosure SIMATIC RF300 System Manual, 11/2009 - Zwischenstand 17.09.2009, A5E01642529-04 RF300 system planning 4.7 EMC Directives If the control cabinet panels are insulated from each other, a high-frequency-conducting connection can be established using ribbon cables and high-frequency terminals or HF conducting paste. The larger the area of the connection, the greater the high-frequency conductivity. This is not possible using single-wire connections. Prevention of interference by optimum configuration Good interference suppression can be achieved by installing SIMATIC PLCs on conducting mounting plates (unpainted). When setting up the control cabinet, interference can be prevented easily by observing certain guidelines. Power components (transformers, drive units, load power supply units) should be arranged separately from the control components (relay control unit, SIMATIC S7). As a rule: â The effect of the interference decreases as the distance between the interference source and interference sink increases. â The interference can be further decreased by installing grounded shielding plates. â The load connections and power cables should be installed separately from the signal cables with a minimum clearance of 10 cm. 3RZHUVXSSO\ &&(8 6KLHOG SODWH 'ULYH Figure 4-25 Prevention of interference by optimum configuration SIMATIC RF300 System Manual, 11/2009 - Zwischenstand 17.09.2009, A5E01642529-04 93 RF300 system planning 4.7 EMC Directives Filtering of the supply voltage External interference from the mains can be prevented by installing line filters. Correct installation is extremely important, in addition to appropriate dimensioning. It is essential that the line filter is mounted directly at the cabinet inlet. As a result, interference is filtered promptly at the inlet, and is not conducted through the cabinet. &RUUHFW ,QFRUUHFW /LQHILOWHU ,V /LQHILOWHU ,V ,F LQWHUIHUHQFHFXUUHQW Figure 4-26 4.7.6 Filtering of the supply voltage Prevention of interference sources A 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 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. 94 SIMATIC RF300 System Manual, 11/2009 - Zwischenstand 17.09.2009, A5E01642529-04 RF300 system planning 4.7 EMC Directives 5HOD\FRLOV 9DOYHV &RQWDFWRUV %UDNHV Figure 4-27 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. 4.7.7 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. â The equipotential bonding conductor must have a sufficiently large cross section (at least 10 mm2). â The distance between the signal cable and the associated equipotential bonding conductor must be as small as possible (antenna effect). â A fine-strand conductor must be used (better high-frequency conductivity). â When connecting the equipotential bonding conductors to the centralized equipotential bonding strip (EBS), the power components and non-power components must be combined. â The equipotential bonding conductors of the separate modules must lead directly to the equipotential bonding strip.

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. 4.7.8 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. As a rule: â For analog signal cables, the shield should be connected at one end on the receiver side â For digital signals, the shield should be connected to the enclosure at both ends â Since interference signals are frequently within the HF range (> 10 kHz), a large-area HFproof shield contact is necessary 96 SIMATIC RF300 System Manual, 11/2009 - Zwischenstand 17.09.2009, A5E01642529-04 RF300 system planning 4.7 EMC Directives Figure 4-29 Cable shielding The 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. &DEOHWLH 5HPRYHSDLQW Figure 4-30 Connection of shielding bus The 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.

This ensures a large-area, HF-conducting contact. 98 SIMATIC RF300 System Manual, 11/2009 - Zwischenstand 17.09.2009, A5E01642529-04 5 Readers Overview The reader ensures inductive communication with the transponders, and handles the serial connection to the communication modules or the 8xIQ-Sense module. Communication between the transponder and reader takes place over inductive alternating fields. The transmittable data volume between reader and transponder depends on: â the speed at which the transponder moves through the transmission window of the reader. â the length of the transmission window. â the RF300 transponder type (FRAM, EEPROM). â the use of ISO transponders ISO functionality With the following readers, you can also use ISO tags: â SIMATIC RF310R reader (with RS422 interface) â Reader SIMATIC RF340R â Reader SIMATIC RF350R â SIMATIC RF380R reader The readers must either be parameterized for the RF300 or ISO mode. The parameterization is done with the aid of the RESET message frame (INIT-Run). You can find more detailed information on the software parameterization in Product Information "FB 45 and FC 45 input parameters for RF300 and ISO transponders" (http://support.automation.siemens.com/WW/view/en/33315697) or the Function Manual FB 45 (http://support.automation.siemens.com/WW/view/en/21738808) from edition A3 onwards. Note ISO functionality is only possible with certain reader MLFBs. Only the SIMATIC RF310R and SIMATIC RF380R readers with the MLFB 6GT2801-xxBxx are suitable for operating with ISO tags.
