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