FOXBORO FBM233 Redundant Field Device System Integrator (FDSI) Module

The FBM233 Redundant Field Device System Integrator (FDSI) module

provides an Ethernet interface between single- or dual-port field I/O devices and the EcoStruxure™ Foxboro™ DCS.

Each FBM233 module has an RJ-45 connector (10/100Mbps copper Ethernet connection)

on the front of the module for connecting dual-port Ethernet devices.

The FBM233 connects to an Ethernet switch or hub to communicate with one external device or up to 64 external devices.

The combination of a pair of modules provides redundancy at the fieldbus module (FBM) level.

In this configuration, one FBM233 is the master and the other is the tracking module.

Input points on the control station are updated from device input points received on the network connected to the master.

Device output points (depending on the I/O driver) are written by both the master and the trace module.

If the I/O driver detects a problem (e.g. any device loses its heartbeat),

a role switch is automatically performed, or the user can switch roles at any time via the SMDH.
