Hi all,

As mentioned in the title, when i try to delete a connection from PCS7AnOut block this error pops up.

the connection right now is named "SpareAO", but i have to update that symbol to "SpareAO8".
So right now, when i try to compile the chart, this error is coming stating that it does not match the symbol table.
but when I try to update the connection also, this error pops up.

Any help is appreciated.

Thanks, and regards

Likely a SQL project corruption of that chart.

There are some old posts that cover this, example:

If remaking the chart or deleting the offending code doesn't work you will need to open a support request with Siemens to have the project further investigated and potentially repaired.
