RF 300 system planning 4.6 EMC Guidelines 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 a frequent source of interference in plants. Suppression of inductance Relays, contactors, etc. generate interference voltages and must therefore be suppressed using one of the circuits below.
RF 300 system planning 4.6 EMC Guidelines 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.
RF 300 system planning 4.6 EMC Guidelines 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.
RF 300 system planning 4.6 EMC Guidelines Cable tie 5HPRYH SDLQW Figure 4-16 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.
Readers 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.

Transponder/tags 6 Transponders consist predominantly of logic, FRAM and/or EEPROM. If a transponder moves into the transmission field of the reader, the necessary power for all of the circuit components is generated and monitored by the power supply unit. The pulsecoded information is prepared in such a way that it can be processed further as pure digital signals. The handling of data, including check routines, is performed by the control unit, which also manages the various memories.

Communication modules 7.1 8xIQ-Sense 7.1.4 Addressing The address range of the 8xIQ-Sense module is 16 bytes I/O. This is independent of the choice of channel profiles on the connected device (i.e. the IQ profile IDs in HW Config). Access to memory areas A direct association exists between the number of the channel to which the IQ-Sense device is connected (terminal) and the input and output data area of the module.
