  • Page 6: Principles Of Operation

    1. PROFIBUS-PA is designed especially for process automation. It permits sensors and actuators to be connected on one common bus line even in intrinsically safe areas. PROFIBUS PA permits data communication and power over the bus, using intrinsically safe, 2-wire technology according to the international standard IEC 1158-2, but may also be used on the standard RS485 cabling for non-intrinsically safe applications.
  • Page 7 I/O Data Exchange The process of reading the inputs and writing to the outputs is known as an I/O data exchange. Typically, the parameters from each slave device will be mapped to an area of PLC input and output registers or a single function block so that the controlling ladder logic or program interfaces with the device as if it were an internally fitted module.

    " Installation Wiring the System ' " () ) * + Before installing, ensure that the LinkRack wiring is electrically isolated and cannot be made “live” unintentionally by other personnel. Wait 5 minutes after disconnecting power before working on any part of the system or removing the covers from the drives.

    • If the LinkCard is at the end of the network terminating resistors are required. • All other Profibus Devices in the system should not have terminators. Use terminating resistors (Resistors ±5%, ¼ watt or higher) on the LinkCard.if it is at the end of the Profibus network. L5353 Profibus 0Vdc NETWORK STATUS...

  • Page 14: Programming Considerations

    Programming Considerations The maximum amount of either input or output data that will fit in the DataExchange message is 244 bytes. The C_PBW and C_PBR blocks each require 16 bytes (8 words). So the maximum number of each type of block is 15, which is 240 bytes. If the total number of C_PBW and C_PBR blocks are limited the maximum to 27 or less, the blocks may be declared in the Profibus Master individually...
