Hi,  
how can I read a TAG with dynamic path in SFC transition?  
Please any suggestions.

example of Non dynamic works fine:  
{[default]Assembly\_Cells/PAC\_S1/OPC/Line\_Status}

I want tho have "PAC\_S1" part dynamic. Stored in chart variable.

thank you

It is an expression, so you can use the `tag()` expression:
