System Architecture & Signal Flow
The 720254 module installs into the CENTUM VP field control station (FCS) chassis. Once seated, it is recognized by the CENTUM VP Engineering Environment and configured via the system’s standard I/O builder. Serial signals from field instruments or subsystems are received, buffered, and passed to the FCS processor over the internal V-net/IP or Vnet bus, depending on system generation. The module supports point-to-point and multi-drop serial topologies, enabling flexible field device connectivity without additional protocol converters.
