Profibus Bus Interface Unit

The Profibus Bus Interface Unit interfaces Field Control I/O modules to a Profibus I/O bus.

The intelligent processing capabilities of the Profibus Bus Interface Unit allow the

configuration of features such as fault reporting, selectable input and output defaults, analog

scaling and analog range selection for the modules in the station. In addition, the Profibus

Bus Interface Unit performs diagnostic checks on itself and its I/O modules, and relays

diagnostic information to the host (if configured for fault reporting) and to a Hand-held

Programmer.

The Bus Interface Unit mounts on a Bus Interface Unit Terminal Block. The Bus Interface

Unit can be removed and replaced if necessary without removing the wiring or

reconfiguring the I/O station.

Bus Interface Unit Terminal Block

The Bus Interface Unit Terminal Block provides connections for power wiring and single

or dual communications cables. The Bus Interface Unit Terminal Block stores the

configuration parameters selected for the station.
