Configuration Changes In An Input Module; With Multiple Owners - Rockwell Automation Allen-Bradley FLEX 5000 User Manual

Configuration Changes in
an Input Module with
Multiple Owners
Controller A sends new configuration to the module.
You must be careful when changing the configuration data of an input module in
a multiple owner scenario. If the configuration data is changed in owner A and
sent to the module, that configuration data is accepted as the new configuration
for the module. Owner B continues to listen unaware that any changes have been
made in the behavior of the input module, as illustrated.

IMPORTANT A message in Logix Designer alerts you to the possibility of a multiple
owner-controller situation and lets you inhibit the connection before
changing the module configuration. When changing the configuration for a
module with multiple owners, we recommend that you inhibit the
connection.
To prevent other owner-controllers from receiving potentially erroneous data, use
these steps when changing the configuration of a module 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 Logix Designer to change the configuration, see
Chapter 6.
3. Repeat step 1 and
changes in each.
4. Clear the Inhibit checkbox in each owner-controller configuration.
