IIMCP02 Multibus Communication Processor Module
The multibus communication processor module (Fig.
) con-
tains a library of commands that send and retrieve data from
process control units and other operator stations. The OIS con-
sole sends commands to the multibus communication proces-
sor module via a SCSI bus. The module is configured by setting
dipswitches. All the jumpers on the board are factory set and
should not be changed (Table
). Refer to Table
for the
dipswitch settings. The IIMCP02 module is required for
INFI-NET systems with up to 30,000 tags.
NOTE: Make certain termination resistors RN2, RN3 and RN4 for
console installation are removed.
