800xA Extend from closed library
I want to give the ACSStdDrive some extra functionality and want to show this in an extra tab on the faceplate.
So I make an instance of an ACSStdDrive in MyACSStdDrive.
1) I don't want ACSStdDrive to act as an alarm owner. MyACSStdDrive must be the alarm owner.
2) I don't want to inherit the MainFaceplate, because they create an extra tag count in the system.
Is this possible to do?

1. I don't think Alarm Owner can be changed in a released library... :-(
2. By turning off Aspect Object, no object will be seen in Plant Explorer, hence no tag will be drained
I don't know if its feasible to disable all standard alarms and implement your own?
You can break the alarm ownership by adding a block in-between that isn’t an alarm owner.
Example:
MyACSStdDrive (alarm owner) -> DummyBlock (not alarm owner) -> ACSStdDrive (alarm owner).
This will force all alarms and events from the ACSStdDrive to be associated with the MyACSStdDrive instead.
