But It's necessaryto show qualityfor every tag, I'msuppose to shadow I/O Field, if tag has bad quality, but I have no idea, how to get quality without scripting.I'm using WinCC Flexible 2007 HF4.Could you help me? Thank you for all your suggestions! Best regards, Nickolay

Go to the properties of the tag wich is shown in the IO-field. At the properties you find the point limits there you can add lower/higher limits. So if this tag will be changed by your plc programm the IO-field show you the colors for the overstep limits. The color of the limits of the IO-field must be edited at the IO-field and not at the tag. Attachment limit.JPG (206 Downloads)

On the other hand you can make some "alive" signal in PLC and try to use it in Flexible script for testing connection. I think its enough one signal for all tags because all tags runs on the same connection. If connection lost then you should not get this "alive" signal.
