Completing the Configuration of a Modbus Plus Supervisory Network with

Momentum Components (Using Modsoft)

Overview To complete the configuration of the supervisory computer at Modbus Plus address

1, create a Peer Cop screen that accesses the CPU at address 3 and defines the

references for that CPU.

Accessing

Node 3

Using the AddNode command, create a new Peer Cop screen with a Link setting of

1 and a Node setting of 3.

Specifying

References for

Node 3

We know that this M1 CPU sends 16 words of specific output to the supervisor and

receive seven words of global data from the supervisor. Follow the steps in the table

below to define the registers that the supervisor will transmit to and receive from the

M1 CPU at Modbus Plus address 3.

Step Action

1 In the REFERENCE column of the SPECIFIC INPUT field, type the value 400020,

the first register which will receive the input. Push <Enter>.

2 Type the value 16 in the LEN column of the SPECIFIC INPUT field, indicating the

number of registers that will be received. Push <Enter>.

3 The GLOBAL OUTPUT fields should already be complete, since you filled them out

for node 2. The completed Peer Cop screen should look like this:
