    I try to call method through OPC UA Server with UaExpert as OPC UA client.
    I use CODESYS Control Win V3 (

    1. I edit devdesc:

    2. I create simple project with one FB and one method:

    3. I add symbol configuration and set option Support calls...

    4. I add my FB to symbol configuration and set "execute" permissions for FB and method.

    5. I download and start project.

    6. In UaExpert I see my FB (but don't see method) and command "Call" for FB not active.

    So how I can call methods through OPC UA?
    It would be great to see a simple example, maybe make sense to add it in FAQ: ... plications m

    this is the way it will work for the future yes,
    but there are missing two jiras ( see no release date on this) to have it up and running that way.

    Thank you for info.
    I was confused with this new target setting and CDS-64761 (this issue looks like this feature already works).
    By the way, it will be nice to see example in FAQ after support this feature.
