I cant seem to get over a 100 deviation alarm on my PID block.
It has to do with the display element. If you can access the graphic editor for that faceplate. The visibility of the deviation alarm is set to be visible when the Pdevmax is less than or equal too the Z.YParameters. With it being a PID block chances are it is 0-100. Changing the < to a > will fix the issue. Then go to your function diagram and make the Pdevmax 999999.0 compile and download and then you should be able to adjust the alarm limit as required from the HMI (faceplate)
