PLC ack tag

Yngmalv Posts: 1 Rating: (0)	Hi, is it possible to create a PLC acknowledge tag in WinCC flex 2008 sp2? when I press ACK button on alarm screen I want to set a bit to 1 in my plc. I read in the FAQ that when configuring in WinCC flexible the "trigger address" and the "acknowledge bit" for error messages are assigned automatically. How do I know which byte this is?
