Foxboro FBM233 Field Device System Integrator Module, 10/100 Mbps Ethernet, Redundant

 Product Details:

FBM233 P0926GX Datasheet.PDF

Each FBM233 module has a single 10/100Mbps copper Ethernet connection and a single RJ-45 connector on the front of the module for connectivity to dual-ported Ethernet devices. 

The FBM233 is connected to Ethernet switches or hubs in order to communicate with one external device or up to 64 external devices.

A pair of modules combine to provide redundancy at the Fieldbus Module (FBM) level. In this configuration, one FBM233 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 problems are detected (for example, loss of heartbeat from any device) by the I/O driver, or the user can switch the roles at any time via SMDH. 

The general network configuration is shown in Figure 1.
