You don't need to create script.

Simply create one tag in HMI project. On the tag properties actions

On select Change HMI and configure the tag according to its status value

I'm trying to define the tag but can't seem to call different screens for the different value. only true events - valuechange I'm able to call a screen, but that's only 1.

Could you give some further assistance?

Hello stvank,

please provide details to your question to receive a good answer:

What do we need to solve your problem?

Which WinCC Version do you have?

TIA portal V15.1 update 6

WinCC Advanced V15.1 Update 6

Thanks Murof,

But I was allready aware of these 2 methodes. Problem with the area pointer is that I have to adjust the plc program, which I don't want to.

Problem with the trigger tag is that it only changes at a not defined value change. The tag provided by the plc varies from 1 to 35, depending on wich screen should be called.

The PLC code has MW20 as the page number. The screen capture shows the activation of pages 11 and 12. Or so it seems to me.

Therefore "Screen_Nr" tag in the example Mr Murof shared, is linked to address MW20. The example given by Mr. Murof is the method that will work for you. The screens itself would need to have the page number from 1 to 35.

As a side note.. there is no MW31. MW31 would suggest the bytes MB31 and MB32. The S7-200 only has MB0 to MB31.

Hi qwazee,

You're right, the method Murof discribes works fine. I was a bit to fast and read "activatescreen" instead of "activatescreenbynumber".

Thanks for the help all !
