I/O Driver

The FBM is a general purpose Ethernet hardware module that can be loaded with different software

drivers.

These drivers configure the FBM to recognise the specific protocol used by the device.

Some of these software drivers are standard products. Other custom drivers can be developed to meet

specific needs.

These drivers are dynamically downloaded to the FBM233 with software code

specifically designed to interface with the protocols of third party devices.

The configuration steps and software requirements for each driver are specific to the device integrated

into the system.

Ethernet Link Setup

Data communication between the FBM233 and field devices takes place via the RJ-45 interface on the

front of the FBM233 module.

The RJ-45 connector of the FBM233 can be connected to the field device via a hub or an Ethernet switch.

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

external devices.
