A pair of FBM231 modules combine to provide redundancy at the Fieldbus Module (FBM) level, with field wiring to two termination assemblies (see Figure 1). In this configuration, one FBM231 is the Master, and the other is the Tracker module. Input points on the control station are updated from the device inputs received on the network connected to the Master. Device output points, depending on the I/O driver, are written by both the Master and Tracker module. Role switching is automatic if actual problems are detected (for example, heartbeat) by the I/O driver, or the user can switch the roles at any time via SMDH.

The FBM231 has four ports - each can be individually configured in software for RS-232, RS-422 or RS-485. This allows a single FBM231 the flexibility to connect to multiple similar but not identical devices. Ports 1, 2, 3, and/or 4 can be configured as a single logical port with redundant cables allowing you to interface with dual-ported I/O devices within your plant. The general network configurations are shown in Figure 1.
