Foxboro FBM232

This fieldbus module (FBM) is a generic Ethernet hardware module in which different

software drivers can be loaded. These drivers configure the FBM to recognize a

particular protocol used by the device. Several of the software drivers are standard

product offerings. Other custom drivers can be developed to meet specific needs.

These drivers are dynamically downloaded to the FBM232 with software code

specifically designed to interface with the third party device’s protocol. The

configuration procedures and the software requirements for each driver are unique to

the device(s) being integrated into the system.

Data communication between the FBM232 and field devices are through the RJ-45

connector located on the front of the FBM232 module. The RJ-45 connector of the

FBM232 can be connected through hubs, or through Ethernet switches to the field

devices (refer to Ethernet Switches for Use with FBM232, page 12). Connection of

multiple devices to the FBM232 requires a hub or switch.
