Scheduled Communication
About the Example Application
This example application sends data from one Logix5550 controller (the
producer) to another Logix5550 controller (the consumer). Both controllers
are on the same ControlNet but in different chassis. In both chassis the
controller is in slot 0 and the 1756-CNB module is in slot 1. The 1756-CNB
modules are configured at node addresses 1 and 6, respectively. A Timer
provides the test data for the message.
