Does anyone know why I get this error and how can I fix it?
I am trying to connect my CODESYS program with OPC Client Data Access to Factory I / O, for some unknown reason I get this error.
Please, if anyone knows how to solve it I would appreciate it very much
Can you share your Codesys project file, so I can take a look?
Do you want the project file by mail?
Yes, you can post it here (in a zip archive) or send it to me in a private message.

Now yes, thank you; This is my CODESYS project

I recommend that you update to the latest version of Factory I/O first. Next, try to update CodeSys to version 3.5.11.0. The CodeSys version you are using is quite old (3.5.7.10). I’m attaching a copy of your project which is working fine. Another thing, always build the Symbol Configuration before using global vars as OPC items/nodes:
Note, I had to remove the visualization part of your project since it requires Spanish libraries which on don’t have installed.
