PROFIBUS Coupler

This coupler connects the PROFIBUS system to the electronic terminal blocks, which can be extended in modular fashion. One unit consists of the PROFIBUS Coupler itself, up to 64 terminals for connecting digital inputs and outputs, and one end terminal. The PROFIBUS Coupler supports the operation of all bus terminals, providing input/output information to the controller in the form of a byte array.

  • The PROFIBUS Coupler recognizes the connected terminals and automatically generates the affiliations of the inputs and outputs to the bytes of the process image
  • The first input/output signal is inserted in the first bit of one byte (LSB), beginning from the left, and continues to insert further signals in this byte
  • Inputs and outputs are clearly separated, and a new byte begins automatically when the number of inputs or outputs exceeds 8 bits
  • The PROFIBUS Coupler supports the operation of all bus terminals, with all the input/output information available to the controller’s process image in the form of a byte array
  • Bus terminals can be controlled via function blocks, allowing the PAC to handle all peripheral configurations during start up phase
  • If required, the controller can upload configuration data to a centrally managed data store
  • If a bus terminal is replaced, the controller can automatically configure the required settings on power-up, with no need for manual adjustments
