Scheduled Communications
About the Example Application
This example sends scheduled data from a PLC-5C processor (producer) to
a Logix5550 controller (consumer). The PLC-5C is ControlNet node 11; the
1756-CNB module is node 1. The Logix5550 controller is in slot 0 of the
ControlLogix chassis and the 1756-CNB is in slot 1. The PLC-5C’s seconds
timer (S:23) provides the data for the message.
