I am programming a display for a good size pilot plant. I have encountered an issue where anytime I click on a PID button in runtime the program crashes and closes down. I currently have three configured, and all three buttons have the same issue. I tried deleting components in my PAC Display configuration until there was nothing left except the last PID button and it still crashed. I feel that I have checked most of the obvious settings for the PID loops in my strategy and still can't seem to get it right. Has anyone experienced this and have any ideas as to how I can get these PID buttons working?
