The top indicator is missing because the Process Value is 114% on a scale of 100
Is there a way to make the indicator stay on the bar without affecting the historized value of the tag and maybe indicate the value is off scale?
Sure. Put a custom property that is bound to the tag. Then put an expression on the indicator value along the lines of if tagvalue is greater than 100 then 100 else tagvalue
Clamp and/or scale in the PLC.
