It works but I also get the name of the TC project and the name of the PLC project in front of the variable name. I should be able to figure a way to get rid of what I don't need using some string functions.
'Tc3_TestRecipe.PLC_TestRecipe.Main.fbTest[0]'
I only need 'Main.fbTest[0]'
Thank you.

Those items you don’t want are part of the instance path, that is why they are included. Simply make a function that starts at the string end, and goes backwards until it finds the second period. Then return the MID of the string, starting at that point.

Hi,
Is it possible to use __VARINFO inside a Function block to get info on the instance of the function block like this:
stVarInfo := __VARINFO(THIS^);
If I do this in TwinCat, VisualStudio crashes. I would like to get the name of the instance of the function block from inside the function block.
Thank you.
If you just want to have the instance name you can use this attribute pragma:
