I was wondering how could I write up expression for this cases:
1st case: object A changes color this way: when Q0.1 is on 1 AND Q.2 on 0, it's red. When Q0.2 is on 1 AND Q0.1 on 0, it,s green. In all other cases, it stays in current color.
2nd case: object B changes color from red to green as soon as Q0.3 gets on 1 and stays green until Q0.4 gets to 1, which sets it back to red. Just like SR flipflop.
Thank you for help in advance.

Re: WinCC 7.0 expression
Hi, there ar some way to do this.
I suggest to create a simple logic into a plc and set/reset bit in a data block ( db.dbx... ) use this bit in wcc to change color.
( this is the way that i prefer )
Otherwise you can create a script (VB or C ) directly in wcc in the color propreties ( right click .... script .... )
You can write a function in C or VB editor and recall in color properties ( dinamic ... )
( i use this way in case of multiple object )
bye
