Hello.
What is the right procedure for online change of AI module configuration parameters (input range) with redundant AI modules (over ControlNet) and redundant controllers.
Thank you very much.

P.S. I once had a problem with online AI module configuration change on the same system. When I did the change (I inhibited the AI module first) card produced an error wich was resolved after stoping the PLC and restoring backup application on the controller. Now, this is not the option, it needs to be online with no errors, so please respond if you are sure. TX
