Using the Modbus Plus Ports

Peer Cop

What Is Peer A Momentum M1 Processor Adapter has the ability to define point-to-point

Cop?transactions between itself and other devices on the Modbus Plus network. The tool for defining these transactions is a panel software configuration utility known as Peer Cop.

Configuring

Each device on the network can be configured to send and receive Peer Cop data.

Network Devices

λ In a Modbus Plus I/O networking architecture, the CPU on the network can be

with Peer Cop

 

 

used to configure the entire Peer Cop database.

 

 

λ In a Modbus Plus supervisory architecture, each CPU on the network needs to

 

 

be configured to handle the Peer Cop data that it will send or receive.
