Chapter 3: Operation Within the ControlLogix System
Owner’s Guide 0300199-01 Rev. D
Exercise caution when changing an input modules’ configuration data in a
multiple owner scenario. When the configuration data is changed in one of the
owners, for example, Controller A, and sent to the module, that configuration
data is accepted as the new configuration for the module. Controller B will
continue to listen, unaware that any changes have been made in the module’s
behavior.
Important: When changing configuration for a module with multiple owners, we
recommend the connection be inhibited. To prevent other owners from receiving
potentially erroneous data, as described above, the following steps must be
followed when changing a module’s configuration in a multiple owner scenario
when online:
1.
For each owner-controller, inhibit the controller’s connection to the
module in the software on the I/O Module Connection tab.
2.
Make the appropriate configuration data changes in the software.
3.
Repeat steps 1 and 2 for all owner-controllers, making the exact same
changes in all controllers.
4.
Uncheck the Inhibit box in each owner’s configuration to reconnect
each module.
