Connections Example
In this example system, the 1756 ControlLogix controller:
• controls local digital I/O modules in the same chassis.
• controls remote I/O devices on a DeviceNet network.
• sends and receives messages to and from a CompactLogix
controller on an EtherNet/IP network.
• produces one tag that the 1794 FlexLogix controller consumes.
• is programmed via RSLogix 5000 programming software.
The ControlLogix controller in this example uses these connections:
