Hi all I really need your help on this one... I have tried to implement this alarm feature in a 300-CPU using SFC 107 (alarm message )and SFC 19 (read acknowledged). The problem is that every time I have more than one alarmfrom within the same datablockin the alarm list in WinCC (V.7 sp1.) and then groupacknowledged all these alarms then... 1. All alarms is acknowledged correctly 2. If the alarm condition for ei. 2 alarms is corrected in 1 scan then only one of my alarms is removed from my alarmlist. But.. 3. If I acknowledged each alarm for each alarmstep then all alarms is handled correctly. 4. If i wait to acknowledged all alarms until they are gone, then all alarms is removed from the alarmlist correctly. The only way to get this 'hanging' alarm- is to restart the CPU. Anyone??? - I have attached some screendump off my code, maybe this could help solving this BIG problem AttachmentWinCC_Alarms.zip (105 Downloads) |
