Using Peer Cop with Modsoft
870 USE 101 10 V.2 297
Defining References for the Supervisory Computer
Overview At this point, we will attach the Modsoft 2.6 programming panel to the AT984
supervisory PLC at Modbus Plus address 1 and set up two Peer Cop screens to
handle the M1 CPUs at addresses 2 and 3.
We know that the M1 at Modbus Plus address 2 is sending eight words of specific
output to the supervisor and that the M1 at Modbus Plus address 3 is sending 16
words of specific output to the supervisor. The supervisor will receive this data as
specific inputs.
We also know that the supervisor is sending 10 words of gl ob al dat a, part s of w hich
will be received by both of the M1 CPUs.
Accessing
Node 2 Make sure the Link setting is 1 and the Node setting is 2, indicating that the
supervisory computer will exchange data with the CPU at address 2.
