Problems with CODESYS OPC and FactoryIO

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?

This is my CODESYS Projectc, In the compilation I don’t have any errors.

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 (63.4 KB)

I recommend that you update to the latest version of Factory I/O first. Next, try to update CodeSys to version The CodeSys version you are using is quite old ( 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.
