Configuring a Modbus Plus Network in Concept with Peer Cop
870USE10110 July 2004 333
Defining the References for the Next Node
Overview We now want to attach the Concept programming panel to the 171 CCS 760 00
Momentum M1 CPU at Modbus Plus address 3 and create a similar Peer Cop for
this device to communicate with the supervisory PLC at Modbus Plus address 1. In
this case, we want the M1:
to send 16 words of specific output to the supervisor
to receive the last seven words of global input from the supervisor. (Remember
that the supervisor will be transmitting a total of 10 contiguous words of global
data over the network.)
Defining Specific
Outputs
Follow the steps in the table below to define the specific output in Peer Cop.
Step Action
1 Click on the Specific Output... button.
Result: The Specific Output dialog box appears.
2 Since you are addressing the device at address 1, you will use the line for Source
1. Type the value 400024 on that line in the Dest. Ref. column.
3 Type the value 16 in the Length column, indicating that 16 words of data will be
exchanged. In this case, we will leave the default BIN setting.
4 Click <OK>.
