We have an S7-1500 where we generate alarms by the function 'program alarm'.

But problems occurs when you put 0 on program_alarm.enable and in this time change program_alarm.signal 1->0. (f.e. situation when you stop PLC and download there modified program)

We can't delete program_alarm after this situation, because program_alarm working on edges and we have got 0 on program_alarm.signal but alarm is still active...

So my question is:

Is possible to delete all active program_alarms?

Hi 

If your program less than 3 Mb please attached it I would like to see your caase online 

Hi

Any solution for this problem?

I use TIA 13 SP1 update 9

Best Regards

Only Solution:

with acknowledgement call Programm_Alarm with each Instance used for creating the alarms again with SIG = false - maybe a lot of work, but only workaround I found when it's [messed] up.

If this is not enough, create a process, that triggers SIG from true to false during the call.
