Why is there still 1 alarm in Buffer after the flag S.HMI.ALACLEAR has been activated?

FAQ #101439

The used of the internal flag S.HMI.ALACLEAR works but there is always 1 alarm left in Buffer and the only way to clear it is to download the user programme again. This situation is caused due to a specific "unhappy"configuration of the "alarm Buffer".

 

Reason
The problem is caused because the option "Buffer mark: Start" has been chosen. Below you can see the parameter setting constellation which leads to this misfunction:

Solution
Change to: "Buffer mark End":

It is advised to use the default setting whenever possible.

Remark
Due to the fact that this problem is caused by the constellation of the above shown parameters of the alarm buffer configuration it is very likely it exists since the first release of the HMI Editor. There is no modification which works around this situation planned.
