Example 4: Control
Distributed I/O
In this example, one SoftLogix controller controls distributed I/O through a
1794-AENTmodule.
This example has Soft1 controlling the I/O connected to the remote
1794-AENT module. The data the SoftLogix controller receives from the
distributed I/O modules depends on how you configure the I/O modules. You
can configure each module as a direct connection or as rack optimized. One
chassis can have a combination of some modules configured as a direct
connection and others as rack optimized.
All analog modules require direct connections. Diagnostic modules support
rack-optimized connections, but require direct connections to take full advantage
of the diagnostic feature.
