About the Example Application

Adding an I/O Chassis to an Existing
ControlNet Network
Each 1756-CNB interface module can support up to 64 bidirectional
connections. This example application expands the ControlNet network
from the previous chapter by adding another remote I/O chassis. The new
remote chassis contains another "child" 1756-CNB module (configured as
node 3) in slot 0 and an analog output module in slot 1. The ladder program
of the previous chapter is modified to produce a varying signal at one of the
analog output channels. Note that these changes do not affect the operation
of the digital I/O modules in the first remote chassis.
