First of all, I want to thank the contributors to this forum, where we can get the support to keep growing and learning about this software.
Now, I have the following technical question: I have created a group of variables called that with the integer-type state changes supplied from the PLC, states number 0 and 6 represent machine inactivity, and only state 3 is the one that means the machines are fully operational or in active service.
So far, everything is fine; even though I have already been able to "graph" their states using the DB TABLE HISTORIAN, I have been asked if it is possible for another screen in the same project to show a numerical "update" (minute by minute) in a display-like manner (e.g., LED Display). Possibly, it is because I haven’t found the exact location to extract that data in real time.
WOULD IT BE NECESSARY TO CREATE A QUERY TO MY DATABASE? (ALTHOUGH IT COULD BE MORE COMPLEX, THE DATABASE I HAVE IS IN POSTGRESQL)
I hope you can help me. Thanks a Lot...
Best Regards!!!!
