Allocating Communication Connections A-5
To configure an I/O module for a rack optimized connection, you select the
Rack Optimization communication format. Most discrete I/O modules
support a rack optimized connection. If this option does not appear when
you are selecting communication format for an I/O module, the module
does not support the rack optimized connection.
Combining direct and rack optimized connections
A remote chassis can have both a rack optimized connection and direct
connections to analog or digital I/O. In this example, the owner controller
uses a rack optimized connection to communicate with two digital I/O
modules. The owner controller also uses a direct connection to
communicate with an analog module in the same chassis.
