Symbols and their attributes inside FBs

[swillemsACCIO]

Hi there,

I have an instance of an FB and inside the FB another FB:
{attribute 'AF_VisuButton'}
fbTestButton : FB_VisuButton;

Loading all Symbols or all DataTypes never finds the attribute of the DataType FB_VisuButton.

However, reading the values directly is working: readValue('Instance.fbTestPage.fbTestButton')

How can I read all DataTypes and all Symbols?

The OPCUA-Server from Beckhoff finds all attributes even in nested FBs.

Thanks you very much in advance for your help.

Best regards

Stefan
