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.
