Specifying References for Input and Output Data on a Modbus Supervisory
Network with Momentum Components (Using Modsoft)
Overview We will now set up the 171 CCS 760 00 Momentum M1 CPU at Modbus Plus
address 2. This device will:
send eight 4x registers of specific output to the supervisory computer at Modbus
Plus address 1.
receive five 4x registers of global input from the supervisory computer. These
registers are the first five registers in a 10-register block broadcast by the
supervisor.
Defining the
Specific Output
The following table describes how to define the specific output in Peer Cop.
Step Action
1 Move the cursor to the REFERENCE column of the SPECIFIC OUTPUT field with
the cursor arrow keys.
2 In the REFERENCE column of the SPECIFIC OUTPUT field, type the value
400016. Push <Enter>.
Result: The cursor moves into the LEN column of the SPECIFIC OUTPUT field.
