1-2 Understanding Your Programmable Controller
For a PLC-5 controller to control I/O modules, both the controller and the
I/O modules must be directly attached to the same network.
Evaluate what communications need to occur between controllers. If there is
sporadic information that is not time-critical, use a message-based network
such as an EtherNet/IP (the information portion) or Data Highway Plus
TM .
Identifying Controller
Components To become familiar with the controller’s front panels, use these figures:
