SOLVED
It seems that Node Red does not recognize Ctrl X and its variables, which is strange because not long ago it was working normally.
Hi @Gabriel_Estrela,
the error message DL_INVALID_ADDRESS lets me guess, that the nodes you are trying to access in the Data Layer are not present or that the path does not match.
You can check that in the Data Layer Browser at Settings -> Data Layer of the ctrlX CORE Web Ui or you can also look directly in Node Red when you look at the settings of the Subscribe-Node.
The data you are trying to access is provided by the PLC, if this data is not present in the Data Layer you should have a look into your PLC project.
Atentamente
Nick
