Hello, 

I am having trouble with something which was simple in previous (non-unified) version of WinCC. 

I have a mimic FB that I use in TIA (1500CPU) which moves integers in to a tag that I use to colourise certain visual aspects of my screens. 

This is my first venture in to Unified, so please excuse any ignorance. 

I have the following integers available from my FB: 

0 - Stopped

1 - Running

2 - Fault

3 - Safety Issue

I have created a object (a simple circle) and I am trying to adjust the background colour using these integers. 

I have set the background to dynamic using a tag - selected range and configured the ranges as follows: 

0 - Grey

1 - Green

2 - Red

3 - Blue

If I move 3 in to the tag, the circle goes blue. If I move 2 in to the tag it goes red. If I move 1, it goes green, if I move 0 it goes grey. If I do it in a certain order. Trouble is, if we are running (1) and the system faults (2) when you reset the fault it goes back to stopped (0) but the color goes green on the HMI (1). The tag correctly contains a 0 but shows as green. 

I think the problem is when I am using 2 and 3 integers, it cannot seem to get back to 0. It goes back to the last used colour. If I am stopped (0) and the fault occurs (2) it goes back to grey (0) as it was the last used color. 

Any help please as this is baffling my brain and was very easy to achieve using non-unified versions of Comfort screens!

Definitly it's a very strange behaviour. Could you specify which TIA Portal version and UCP firmware you're using? A detailed screenshot of the dynamization would be nice too.

 TIA Portal V18. 

I'll attach some screenshots as a zip file. If you need more please let me know. 

I can also confirm the exact same code works within a 12" Comfort (non-unified) HMI with the same project on the same CPU.
