Hello everybody,

I am streaming pictures using the File Source, however, I am getting the exception below at line 12. The F_VN_CopyIntoDisplayableImage function is throwing an unknown exception.

I would appreciate if anyone guides me through how to fix this error. Thanks a lot in advance!

If I use F_VN_TransformIntoDisplayableImage instead, I don't get an exception until I open the 'ADS Image Watch' window.

Found the problem!!! 

I was running an older version of TwinCAT 🤯 

That's what I had.

From the infosys website, the minimum version should be 4024.17 at least.

After installing the latest version, I was able to get it working!
