Removing I/O Modules

When you remove an I/O module, any dependent configuration is updated to maintain data integrity and prevent broken references as explained below:

• When you delete a module, the module and its associated channels are removed. If any of those channels are part of a group, they are removed from that group.

• Only Alarms or Jobs attached exclusively to those channels are deleted. Shared Alarms or Jobs are retained.

• If the module contains calibrated channels, a warning displays before deletion because calibration data may be affected.

NOTICE
RISK OF DATA LOSS OR CORRUPTION Deletion cannot be undone. Ensure any required data is archived before proceeding. Failure to follow this instruction can result in data loss
