5. On the General tab, click Change...
The Module Definition dialog opens.
6. Enter values for Connection, Chassis Size, Electronic Keying, and
Revision.
Connection choices include:
• None – the adapter makes a direct connection to each of the modules
referenced by the data.
• Rack optimization– digital I/O data is collected into a rack image. This
does not include analog or specialty I/O modules.
• Listen only - rack optimization– read or verify data only, but does not
control the modules. When you have multiple controllers - one controller
is used to control and the other controllers are used to monitor.
7. Choose Rack Optimization from the Connection drop-down list, because
we are making a mixed connection that includes both a direct connection
and rack-optimized connection.
8. Click OK.
