changing object colour from multiply variables

changing object colour from multiply variables

Hello,
I have an analogue level the then 4 alarms for each analogue that are generated in my Beckhoff Twincat PLC. The alarms are High high, High, low and low low.
I would like the analogue to be displayed to change to red (alarm state) when either of these 4 variables are in alarm.
I can change colour on 1 alarm by putting it in the line colour dynamic of the analogue variable but how do I do this on alarm 1 OR alarm 2 OR alarm 3 OR alarm 4?
I could do this OR logic in the PLC but I have many analogues therefore would have to create 100 extra tags in the PLC and import then to ZenOn - this will not be good as they will only be required for Zenon display..
Thanks for your continuing support for me developing this product.
Matt
