Functions
This FIP Bus Controller (FBC) is a two channel bus
controller that occupies a single half-slot in an IC697
PLC VME Integrator rack. The FBC is configured
with MS-DOS or Windows based programming
software. I/O devices on the FIP bus are scanned
asynchronously by the bus controller and I/O data is
transferred to the CPU once per scan.
Up to 31 Bus Controllers, of any kind, can be included
in an IC697 PLC system. Of the 31 Bus Controllers, a
maximum of four can be FIP Bus Controllers.
A FIP bus may serve:

Remote Drops, IC693 I/O racks that are interfaced
to the bus through Remote I/O Scanner Modules.
Each remote drop can include any mix of discrete
and analog I/O modules.

Field Control Stations, Field Control I/O modules
that are interfaced to the bus via a FIP Bus
Interface Unit (BIU).
