Peer Cop
What Is Peer
Cop? A Momentum M1 Processor Adapter has the ability to define point-to-point
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
Network Devices
with Peer Cop Each device on the network can be configured to send and receive Peer Cop data.
l In a Modbus Plus I/O networking architecture, the CPU on the network can be
used to configure the entire Peer Cop database.
l 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.
Four Types of
Data
Transactions Peer Cop allows you to define four types of data transactions:
Sources and
Destinations Peer Cop uses defined data references (like PLC discretes or registers) as sources
and destinations. For example, a block of registers can constitute the data source
for the transmitting device, and that same or another block of registers can be the
data destination for the receiving device.
