Hi JamesR,
I am confused. Do the developers of DSC 8.5 really want the "clear time" property not to function and no new instances of an alarm be generated until the existing alarm is acked and returned to normal. It seems that you would want to know when an alarm cleared why else would you have a field that says "Clear Time". I suspect that DougM's post back in August 2006 is still true and that it is a bug that is still not fixed in DSC 8.5. Any information you can provide would be helpful if I am incorrect.
Thanks.

George,
I've recently posted a problem which is exactly what You describe here.
I did not find your post when I was looking for a solution to the problem.

In my post I describe, in other words, the same situation... I have also attached a vi to experience the problem.
So in LabVIEW 8.6.1 it is still a unsolved bug!
Do You know whether it has, at least, a Corrective Action Report Number (CAR Number)?
I am going to put a link to your post in my post...
we'll see

6 years later...
Labview DSC is still having problems with setting an alarm to user ack:
- The API for setting the alarm sto user ack does not work
- Setting a shared variable to user ack with property nodes does not work
- The work-around is to write 2 to the "secret alarm variables" vis PSP (e.g. \\ hostname \ Process \ variable \ alarms \ HiHi \ Acktype )
Labview DSC is still having problems with the behaviour of user ack alarms and alarms in general:
- The ack type settings does not persist after putting the process to pause.
- Sometimes we get ghost alarms: they can not be acknowledged, and they never get cleared(!)
- Alarms are never cleared, even if the variable is not in an active alarm state anymore (except when acknowledged).

Hi langedrag,
I would like to assist you in resolving these issues but I will need some more information. Can you tell me what you are trying to accomplish with the user acknowledge alarms? Do you have some code that I could use to try and reproduce this issue? Have you had a chance to look at the example code for user acknowledge alarms in the NI Example Finder. It is a pretty good resource on how user acknowledge alarms are best used.
Regards,
Josh B
