Support Questions / Re: Doing math in HMI / Internal Tags

Sorry, I explained that poorly.  The message only has to be displayed on the HMI, but can be input by the supervisor through a keyboard.  Some of our PLCs do not handle strings well so I would like the content of the message to reside in the HMI program.  Same thing with the math, I think it should be easier to do on the HMI PC vs. the PLC.  I want something similar to the attached images.

Thanks

Support Questions / Doing math in HMI / Internal Tags

I started trying to create a simple andon type display with rate, count, and goal.  I was able to display my values from the PLC with no problem.  I want the font color of the count to change based on the percentage it is from the goal.  I tried to enter the expression in the limit property of the analog display with no luck.  Do I need to create an internal tag, do the math and then reference that?  Another feature I wanted was for the supervisor to be able to input a text message to the operators.  This message would in no way be part of the PLC.  The message box displayed an error without a PLC tag.  Lastly, is there a way draw lines and basic shapes.

Thanks
