Hi,

I'm facing a strange problem using WinCC Advanced 14 with updates, while reading a tag inside a script.

I've a digital tag that is connected to the plc, with cyclic continuous acquisition mode, and the tag triggers a script. The script tries to read the value for the same tag (using SmarttTags()) but SmartTags returns always 0.

Also if I've an internal tag (with fixed cyclic mode) and I try to read it using SmartTags() in a script triggered by a screen button, on certain script it works and on others it fails. I was not able to detect any difference between scripts those work and those that do not work. Please note that tags used are shown in the same window of the button that triggers the script.

Thanks

Hi,

can you help me? Thanks!

Hi cri2017

Maybe it’s more useful if you move your post to SIMATIC WinCC (TIA Portal) Part.
