Configuring a Modbus Plus Network in Concept with Peer Cop
396 870 USE 101 10 V.2
Defining References for the Supervisory PLCOverview At this point, we will attach the Conc e pt 2.1 programming panel to the
ATRIUM 180-CCO-111-01 supervisory PLC at Modbus Plus address 1 and set up
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 globa l dat a, p arts of which
will be received by both of the M1 CPUs.
Defining the
Specific Inputs First we will define the specific inputs to be received by the supervisor.
