We haven't used Codesys, but you will need to use our U12 driver, which is considered an external library. You may need a toolkit for that functionality, and I am unsure about additional .xml, .eds, etc. files. There's a Codesys forum topic on using an external C library, and you will want to look at the Codesys manual about external libraries.
Alternatively, look into using the built-in Python language in Codesys, and use that with our Python interface which uses our U12 drivers.
Also, consider posting questions on the Codesys forum.
