System overview 3.2 RF300 3.2 RF300 3.2.1 RF300 system overview SIMATIC RF300 is an inductive identification system specially designed for use in industrial production for the control and optimization of material flow. Thanks to its compact dimensions, RF300 is the obvious choice where installation conditions are restricted, especially for assembly lines, handling systems and workpiece carrier systems.
System overview 3.2 RF300 3.2.2 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.

RF300 system planning 4.1 Fundamentals of application planning 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.

RF300 system planning 4.2 Field data for transponders, readers and antennas NOTICE Adherence to the values specified in the "Minimum distance from reader to reader" table is essential. The inductive fields may be affected if the distance is smaller. In this case, the data transfer time would increase unpredictably or a command would be aborted with an error.

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.

RF300 system planning 4.6 EMC Directives 4.6 EMC Directives 4.6.
RF300 system planning 4.6 EMC Directives 4.6.2 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.
RF300 system planning 4.6 EMC Directives 4.6.3 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.
RF300 system planning 4.6 EMC Directives 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.
RF300 system planning 4.6 EMC Directives 4.6.4 Propagation of electromagnetic interference Three components have to be present for interference to occur in a system: ● Interference source ● Coupling path ● Interference sink ,QWHUIHUHQFH VRXUFH GHYLFH HPLWWLQJ LQWHUIHUHQFH H J GULYH XQLW Figure 4-28 &RXSOLQJ SDWK H J FRQQHFWLQJ FDEOH ,QWHUIHUHQFH VLQN GHYLFH DIIHFWHG E\ LQWHUIHUHQFH H J UHDGHU Propagation of interference If one of the components is missing, e.g.
RF300 system planning 4.6 EMC Directives 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.
RF300 system planning 4.6 EMC Directives Coupling paths A coupling path has to be present before the disturbance emitted by the interference source can affect the system. There are four ways in which interference can be coupled in: *DOYDQLF FRXSOLQJ SDWK , 1 7 ( 5 ) ( 5 ( 1 & ( 5),' 5HDGHU &DSDFLWLYH FRXSOLQJ SDWK 5),' 5HDGHU ,QGXFWLYH FRXSOLQJ SDWK 5),' 5HDGHU 6 2 8 5 & ( , 1 7 ( 5 ) ( 5 ( 1 & ( 6 , 1 .
RF300 system planning 4.6 EMC Directives 4.6.5 Cabinet configuration The influence of the user in the configuration of an electromagnetically compatible plant encompasses cabinet configuration, cable installation, ground connections and correct shielding of cables. Note For information about electromagnetically compatible cabinet configuration, please consult the installation guidelines for SIMATIC PLCs.
RF300 system planning 4.6 EMC Directives 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).
RF300 system planning 4.6 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.
RF300 system planning 4.6 EMC Directives 4.6.6 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.
RF300 system planning 4.6 EMC Directives 4.6.7 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.
RF300 system planning 4.6 EMC Directives 4.6.8 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.
RF300 system planning 4.6 EMC Directives &DEOH WLH 5HPRYH SDLQW Figure 4-36 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.
5 Readers 5.1 Overview The reader ensures inductive communication with the transponders, and handles the serial connection to the communication modules/interface modules and 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: ● the speed at which the transponder moves through the transmission window of the reader. ● the length of the transmission window.
