Working Principle
The FBM222 acts as a PROFIBUS master, actively polling connected slave devices over the redundant RS-485 network. It translates the PROFIBUS data into the Foxboro Distributed Control Interface (DCI) format, allowing the FCP to process the field data seamlessly.

Installation Requirements

  • Must be paired with the appropriate FBMSVH or FBM223 Termination Assembly (TA).
  • Requires proper termination resistors on the PROFIBUS network ends.
  • Must be installed in environments complying with Zone 2 hazardous area classifications.

Precautions for Use

  • Ensure the PROFIBUS network is properly grounded to prevent ground loops.
  • Do not disconnect redundant communication cables while the system is in operation.
  • Verify baud rate and device address configurations before commissioning.
