I'm in almost the same boat you are. We are connecting our PCS7 APACS OS to our Allen-Bradley PLCs using DBA to bring in structured "types" so that it automatically associates the new tags with block icons and faceplates already in the system (some are highly customized). Anyhow, getting the basic tags to work is easy, it's this alarming thing that's got me scratching my head. I did find this recently and it helped me a LOT in understanding the eventstate tag and the "chicklets". http://support.automation.siemens.com/WW/view/en/17778440 That is a mapping of the eventstate tag. I put that tag on the PLC and have the alarming and Acks routed to that tag. So, now the PLC and PCS7 are working pretty well together. This is NOT the entire picture, there is something else I'm missing and I believe it relates to EventRaw, so I'm still in research and development mode. My issue now is that when a new alarm comes in, it flashes in both the top banner and on the chicklets just like it's supposed to. However, you have to ack the alarm in both the alarm banner AND on the faceplate to get it to stop flashing. I know that the green check on the faceplate acks the alarm by writing to the eventstate tag, but how come the alarm banner doesn't do the same thing? It seems there are actually two separate systems for alarming and I've just got to get them on the same page. I'm betting it's tied to EventRaw. If you happened to have come across more info, let me know. -Matt |
