Hi, Support.


Is it possible to delete Alarm & event of a specific (absolute) time period ? or few specific alarm or event ?    If yes.. Please explain the same.

Thanks in advance.

Why you want to delete CEL/AML entries?
zenon protects the system against manipulation of the history of the process. A user with respective authorization levels can add/change a comment to CEL/AML entry, e.g. to mark entries where PLC was delivering data with wrong external time stamps etc.
