Connections Example
In this example system the 1769-L35E CompactLogix 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/from a ControlLogix controller on an
EtherNet/IP network.
• produces one tag that the 1794 FlexLogix controller consumes.
• is programmed via RSLogix 5000 programming software.
