Chapter 2 Digital I/O Operation in the ControlLogix System
To prevent other owner-controllers from receiving potentially erroneous data, use
these steps when changing a module’s configuration in a multiple owner scenario
while online.
1. For each owner-controller, inhibit the connection to the module either in
the software on the Connection tab or the message dialog box warning you
of the multiple owner condition.
2. Make the appropriate configuration data changes in the software. For more
information about using RSLogix 5000 software to change the
configuration, see Chapter
7.
3. Repeat step 1
and step 2 for all owner-controllers, making the exact same
changes in each.
4. Clear the Inhibit checkbox in each owner-controller configuration.
