Verify Compatibility
This table shows the compatible pairs of RSLogix 5000 software versions and controller
firmware revisions.
Before You Begin
This section contains information you should understand before installing the CompactLogix
packaged controller.
Restrictions
The maximum amount of expansion modules that can be used with the packaged controllers is
two. Within that limit, the number of expansion I/O modules that can be attached to the
packaged controller depends on the bus current draw of the modules being attached.
Each packaged controller has a specified amount of available bus current as shown in this table.
To determine the number of expansion I/O modules you can add, total the bus current draw
(maximum) of your planned expansion I/O modules and the end cap. If your result is less than
IMPORTANT
The series B controllers are compatible only with the controller firmware and the RSLogix 5000
software versions as indicated in the table below.
Attempting to use controllers with incompatible software and firmware revisions can result in
