Codesys Developers/Users,

User Case: Operator walks up to the HMI, scans his RFID badge on the scanners and the controller automatically logs him in.

I am trying to implement the above and struggling with the VisuUserManagement library. The documentation isn't good and I don't even want to start on pClientData stuff.

Does anyone have a small example project regarding this? How can this use case be achieved?

Or may be if someone can point me in the right direction.

When I used GetNextClient it always returns a null pointer.

Please Help!!
