In this example, assume that each digital I/O module is configured for a rack-
optimized connection to the controller. Analog modules must be configured
for direct connections.
This table calculates the connections in this example.

The rack-optimized connection limits connections, but can also limit the
status and diagnostic information that is available from the digital
I/O modules.
To increase the number of available connections, use a rack-optimized
connection to any remote adapter with multiple digital I/O modules that
permit rack-optimized connections, instead of direct connections to those I/O
modules.
