Configure the Adapter for Direct Connection, Rack Optimization, and Enhanced Rack Optimization in RSLogix 5000 or Logix Designer 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 makes a direct connection to each of the modules
referenced by the data. RPI is disabled in this case.
• Rack optimization– digital I/O data is collected into a rack image. This
does not include analog or specialty I/O modules.
• Enhanced rack optimization – digital, analog, and specialty I/O data is
collected into a rack image.
• 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-optimization connection), choose Rack Optimization as the
Connection for the 1734-AENT/B adapter and click OK.
A dialog box opens.
8. Click Yes.
Series B

The chassis size value equals 1 for the adapter plus the number of I/O
modules installed (physically present on the I/O backplane).
