Slow updating of text (800xA -> 800AC)
For process control i update a text on System 800xA operator interface depending on a status in AC 800M controller.
I have tried two different solutions:
1: Define a STRING variable inside my funktion block in Control Builder and updating the text value in this. When 800xA reads this block, it updates VERY slow - 5-10 seconds delay!!
2: To avoid this delay, i tried to save the text condition to a integer value, and scripting the text in a Graphics builder PG2 label with a long IF THEN ELSE solution depending on the integer value. This solution gives fast updating of the text, but i would like to avoid doing code inside PG2 labels.
Have anyone experienced slow update of STRING variables between controller / System 800xA?
(The controller is running in a soft PLC for now - Could this be a problem for this?)
