Hi

I am using tia18 with a WinCC Unified PC RT and I created a scheduled task to run a script by a tag, however I would like to use a bool plc tag to activate the script every time it goes to true and I only have the Update event, which is called if the tag changes either to false or true.

Is it possible to call the script only on positive trigger?

Thanks in advance!

Moin,

is it possible to trigger on multiple Task and then get the information in the script which Tag was triggered?

Moin,

could u give me an example for that?
I created a Task which triggers on 5 bool tags. In the Events of the Task I inserted a script which should get the Name of the triggered tag.

My approach:

var test = triggerDataSet.HasChanged;
var test = triggerDataSet.HasChanged.Read();

Moin,

thanks for your help but i have a Problem with this solution. For information i use a textfield on my screen to track where my Function quits. (Because i cant see the HMIRuntime.Trace in my TraceViewer)

In my Screenshot u can see my Script. The funtion stops after the Tag Test was changed to "1".

Thank you for your patience. Yes that was the Problem my HMI was at Version 19.0.0.

Is there any chance to get the error code? I mean somwhere had to be a Error like missing Objekt.
