Why not set a bit in the PLC program when the Integer file is equal to 500 and when its not have the bit not true. Then have the indicator refrence the bit rather than the integer? It is good practice to have all the logic in the PLC program rather in the P.V.

PV's don't use expressions like the PV+'s do. You need to write the logic in the PLC to compensate for this deficiency.
DigitalFist is correct. Just write some greater-than...less than logic and set a word value. Move that data into a control registry word, say N7:10. This is the working Data Word.

Use the other words to fire a multistate word in the Panelbuilder software.

You could get this particular function, i.e. "If / Else" with a multistate indicator in PanelBuilder32 by using the Error State as an "anything else" state.

Delete all but two states, but set them for the same Value:



   State0    Value = 500     Normal Color

   State1    Value = 500     Normal Color

   Error                           Alternate Color

Looks simple....

That is very simple...

I do agree I think that all logic should be in the PLC, however, is this logic or just a display preference?

it is for the display
ken if i understand u the error state will display if any other number is seen

Correct

oh good this way i don't have to write more logic to just get the display to work like i want it.
i was trying to stream line a little bit
thanks guys
