Hello ELake20 you are certainly not the first (and most likelywon't be the last), who "struggled" with the DB bit assignment for Alarms (trigger, ack etc.) in WinCC flexible (whose advantage is though that only one tag is used and needs to be created for allalarms). Good news is that Siemens has heard the call for help and offers a couple of solutions: 1.) How can you calculate/determine in advance the bit number for the "Trigger tag" and the "Write acknowledge tag" bit? 2.) DB bit addresses for the "Trigger","HMI ack" as well as "PLC ack"can now be displayed in the discrete Alarm list (right click on the column headers and "tick"them if they are not visible, from memory this was introduced with flex 2008 so you may not have it if you run an older version). I hope this helps |
Cheers |
