PI Connector for FANUC Focus should give a warning to users when they change the machine IP address for an existing data source.
In the PI Connector for FANUC Focus, each data source has the IP address of the related machine specified. The "Device ID" is also part of the configuraiton. If a Device ID is not specified, the IP address is used as part of the Device ID and ends up becoming part of the AF hierarchy as well as the PI point names.
If a user goes to change the IP address for an existing data source, and the default Device ID is being used, they will inadvertently create a second set of PI points (Duplicates, orphaning the original PI points which already have data, potentially) and a second AF hierarchy (Again orphaning the original AF hierarchy).
The UI should give a warning when saving the configuration explaining the consequences of changing the IP address for an existing data source if the default Device ID is being used.
Any configuration changes made to the device id or IP address after initial configuration, will be met by a warning message which the user will have to accept before proceeding with the changes.
