Configuration
Changes in an Input
Module with Multiple
Owners
You must be careful when changing an input module’s 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 on-line:
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.
