System overview 3.2 RF300 3.2 3.2.1 3.2 RF300 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 4.1 Fundamentals of application planning 4.1.5 Permissible directions of motion of the transponder Active area and direction of motion of the transponder The transponder and reader have no polarization axis, i.e. the transponder can come in from any direction, be placed at any position, and cross the transmission window.
RF300 system planning 4.1 Fundamentals of application planning 4.1.6 Operation in static and dynamic mode Operation in static mode If working in static mode, the transponder can be operated up to the limit distance (Sg). The transponder must then be positioned exactly over the reader: 7UDQVSRQGHU 7UDQVPLVVLRQ ZLQGRZ 6J 5HDGHUV Figure 4-2 Operation in static mode Operation in dynamic mode When working in dynamic mode, the transponder moves past the reader.
RF300 system planning 4.1 Fundamentals of application planning 4.1.7 Dwell time of the transponder The dwell time is the time in which the transponder remains within the transmission window of a reader. The reader can exchange data with the transponder during this time.
RF300 system planning 4.1 Fundamentals of application planning 4.1.8 Communication between communication module, reader (with IQ-Sense interface) and transponder Communication between the communication module (IQ-Sense), RF310R reader and transponder takes place in fixed telegram cycles. 3 cycles of approximately 3 ms are always needed for the transfer of a read or write command. 1 or 2 bytes of user data can be transferred with each of these commands.

RF300 system planning 4.4 Installation guidelines 4.4 4.4.1 4.4 Installation guidelines Overview The transponder and reader complete with their antennas are inductive devices. Any type of metal, in particular iron and ferromagnetic materials, in the vicinity of these devices will affect their operation.
RF300 system planning 4.4 Installation guidelines Flush-mounting Flush-mounting of transponders and readers Problem 1RQ PHWDOOLF VSDFHU 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.
RF300 system planning 4.4 Installation guidelines 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.
RF300 system planning 4.4 Installation guidelines 4.4.3 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.
RF300 system planning 4.4 Installation guidelines 4.4.4 Impact on the transmission window by metal In general, the following points should be considered when mounting RFID components: • Direct mounting on metal is allowed only in the case of specially approved transponders. • Flush-mounting of the components in metal reduces the field data; a test is recommended in critical applications.

RF300 system planning 4.6 EMC Directives 4.6 4.6.1 4.
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 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.
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 4-21 &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.
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.
