WinCC Button BAckground color using vb or c

[m1n1 0]

What i would like to do is to change the background colour of a button when a marker bit in the plc is 1. The tag that is addressed to this bit is called "test" I would like to do it with either vb or c script. Has anybody got any simple code that would do this. Also any documentation using vb or c with WinCC would be greatly appreciated. Thanks Edited 22 Jun 2006 by m1n1

Usually I add a little script to the button's "display" property, something like this: const TAG_NAME = "yourtag_name_here" dim oTag set oTag = hmiruntime.tags(TAG_NAME) oTag.read if oTag.value = 1 then item.backcolor = vbred else item.backcolor = vbgreen end if Dont forget to enter the tag name as the trigger (best to avoid cyclic triggers). You could also use the dynamic properties, depending on the "style" of the button.
