How to Call VB Script in TIA from PLC or using PLC TAG when value changed from PLC?

Hello Anklesh

you have to use a Tag trigger to run the Script.

First of all we have to know do you use a Panel, a WinCC Advanced Runtime or a WinCC Professional Runtime?

WinCC Advnaced RT and Comfort Panels:

-> Create a Script in Scripts editor

-> use a Tag -> Events-> Value change for triggering

(do not forget to set the aquisition mode to cyclic continous)

WinCC Professional Runtime:

Here you have a lot of possibilities to do that. But if you want a Script that it triggered independet to the current screens you have to use a Script in Global Script editor and then you can use the "Scheduled Tasks" Editor for triggering (Tag Trigger) Here you have to define the aquisition cycle and other settings.

Hello Anklesh

I already wrote the answer. It doesn´t matter if you use a int or a bool for triggering. Every Tag has an Event" Value Changed".

Use the hints from my post and the last Post from Prof. Frink then you will get is run.
