800xA alarm hiding mask configuration
Voted best answer
Create new Hiding Mask object in Library Structure
Add Hiding Rule aspect(s) on alarm owning objects
Configure some or all alarm conditions that shall be hidden on rule aspect for each object. Select Mask to govern Rule.
Both Mask and Rule allow activation via OPC DA property (both must be TRUE to activate hiding)
Regular hiding can not hide retroactively - this may be added to version 6 at some future time.
