Example 1: SoftLogix
Controller and I/O
Allen-Bradley PLCs
In the following example, one SoftLogix controller controls I/O
through a 1794-ACN15 module.
ControlNet
Example 1: Controlling I/O
This example has the SoftLogix controller controlling the I/O
connected to the remote 1794-ACN15 module. The data the SoftLogix
controller receives from the I/O modules depends on how you
configure the I/O modules. You can configure each module as a direct
connection or as a rack-optimized connection. One location (chassis
or DIN rail) can have a combination of some modules configured as a
direct connection and others as rack optimized.
