Configuring a Modbus Plus Network in Concept with Peer Cop

Specifying References for Input Data
Introduction This section describes how to specify the references for input dat a. In this e xample,
you will start by accessing the device at Modbus Plus address 2, which is a 170
ADI 340 00 16-point input 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 modul e. 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 170
ADI 340 00 sends input data to the CPU, it will be sent to this register.
