GetAlarm
GetAlarm
The GetAlarm instruction gets the highest event level (of user-defined error levels 1 to 8) and the high-
est level event code of the current user-defined errors.
The GetAlarm instruction gets the highest event level and the highest level event code of the current
user-defined errors and outputs them to Level and Code. If there are currently no user-defined errors,
the value of error flag Out is FALSE. If there is more than one use-defined error at the highest event
level, the value of Code is the event code for the user-defined error that occurred first.
