Controlling I/O Over a ControlNet Network
About the Example Application
This example application uses scheduled communications to read data from
a remote digital input module and send data to a remote digital output
module. The example simulates a parts counter operation.
The local ControlLogix chassis contains the Logix5550 controller in slot 0
and the “parent” 1756-CNB module (configured as node 1) in slot 1. The
remote chassis contains a “child” 1756-CNB module (configured as node 6)
in slot 1 and the I/O modules in slots 2 and 3. Network scheduling is done
using RSNetworx for ControlNet software.
The basic procedure given in this example can also be used to configure and
schedule FLEX I/O on a ControlNet network.
