Chapter 1 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.
1-2 Before You Begin Identify the Processor’s Front Panel Components These pictures show the ControlNet PLC-5 processor front panel components.
