Before You Begin
The ControlNet network is a high-speed link that lets PLC processors
and I/O devices (e.g., I/O racks, variable speed drives, Man-Machine
Interface (MMI), and other automation devices) exchange data. The
ControlNet PLC-5 processors have one logical ControlNet port
consisting of two BNC connectors and one network access port; these
processors let you connect to the ControlNet network.
What You Need to Do
