Configure the Adapter for Direct Connection and Rack Optimization in RSLogix 5000 Software Chapter 5
6. Enter or select values for Series, Revision, Electronic Keying, Connection,
and Chassis Size, noting that we used the following values:
Connection choices include:
– none = the adapter will make a direct connection to each of the
modules referenced by the data
– rack optimization = digital I/O data is collected into a rack image. Note
that 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. Because we are making a mixed connection (both a direct connection and
rack-optimized connection), choose Rack Optimization as the
Connection for the 1738-AENT adapter and click OK.
A dialog box opens.
8. Click Yes.
