Using Peer Cop with Modsoft

Specifying References for Input Data
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 3
x
register (300016) as a specific input to the CPU. When the the
170 ADI 340 00 sends input data to the CPU, it will be sent to this register.
