I am writing VBScript in WinCC and cannot figure out how to call up an existing screen in the Script.

I don't remember the key sequence but you can call all the events from a script. I think its cntl shift space bar but I don't remember for sure. I do know if you create a new script it gives you the key sequence at the top for bringing up a list for the events you can call. You can call the screen by name or number just like the event of a button.

Can someone show me some sample code of call routines with in a script and passing variables.

I have posted some code on here before so you should be able to do a search for it. I can post more if you can give me more detail of what you need.

To read/write variables use smart tags.

smarttag("var_name") = 10

my_var = smarttag("tag_name")

Hope this helps

'NOTE: To start scripting please press <Ctrl><Space> and see the wide variety of functions.
'Write scripts by using system functions or the WinCC flexible object model. You can easily access to the
'system through the HMI runtime object. For a convenient picking of an object reference
'you can press <Alt><Right Arrow>. Design complex scripts by employing the basic features
'of the programming language VBScript and access tags directly by name e.g. tag = 5.

Here is a screen shot of a script doing a screen change. I did this with the script wizard. Just select the event you want to happen then apply and it writes the script for you.

Thanks Charles. It works. I am now stuck. How to I pause the script from running while? Is there a way?

 

[CharlesM]

I don't think you can do a pause in the script. You could do half the script set a bit and wait (while bit set loop) till the bit clears. Then in the PLC monitor the bit and reset it with a timer.

You could also put a dead loop in the script that would loop around a few times just to give a short delay.

Why do you need a pause?
