Specifying References for Input Data

(with Modsoft for a Modbus Network with Momentum Components)

Introduction The Peer Cop screen is now set to access the device at Modbus Plus address 2,

which for this example is a 170 ADI 340 00 16-point input module.

This section explains how to specify the reference for input data from this module.

Device

Requirements

When you use Peer Cop to handle a Modbus Plus I/O architecture, you need to be

aware of the type of I/O you are configuring at each network address. Peer Cop does

not know that the device at address 2 is a discrete 16-point input module.

You need to know that a specific input reference with a length of one word (16 bits)

is required to handle this module.

We will assign a 3x register (300016) as a specific input to the CPU. When the

170 ADI 340 00 sends input data to the CPU, it will be sent to this register.

Procedure Follow the steps in the table below to define the specific input in Peer Cop.

Step Action

1 Move the cursor to the REFERENCE column of the SPECIFIC INPUT field, using the

cursor arrow keys.

2 Type the value 300016 in the REFERENCE column of the SPECIFIC INPUT field,

then push <Enter>.

Result: The cursor moves into the LEN column of the SPECIFIC INPUT field.
