  • We are registered at the PROFIBUS®-user organisation.

The advantages

The bidirectional communication with PROFIBUS® PA (Process Automation)offers the following advantages. 

  • Intrinsically Safe Controller
  • Simple and cost effective wiring
  • Number of instruments per segment is related to power consumption (Ex-Zone (EEx ia) max 10)
  • Flexible Topology: Tree, Star or Line
  • FISCO model (Fieldbus Intrinsically Safe Concept)
  • Communication complies with IEC 61158-2 with 31.25 Kbit/s, MBP (Manchaster Coding Bus Powered)
  • PROFIBUS® PA and FOUNDATION FIELDBUS® utilize the same Physical Layer
  • Implementation into PLC Systems via segment couplers via PROFIBUS® DP
  • Block structure, see picture below
  • Acyclic data for Alarms, remote operation, configuration and diagnosis
  • Instruments can be hot plugged (connected and disconnected in operation without interference)
