Logix5550 Controller to PLC-5C:
Scheduled Communications
About the Example Application
This example application sends scheduled data from a Logix5550 controller
(producer) to a PLC-5C processor (consumer). The Logix5550 controller is
in slot 0 of the ControlLogix chassis and the 1756-CNB module (configured
as node 1) is in slot 1. The PLC-5C is configured as node 11. A Timer
provides the data for the message.
