User authorizations

It is possible to assign authorizations for users. This feature can be used to display individual areas per user or to deny certain users access to areas of the app.

This feature is only intended for display within the app. If there is a direct connection to the message broker, all content can potentially be viewed.

Configuration at device level

It is possible to assign user authorization for an entire device (and thus an instance of the function block FB_IotCommunicator). The variable sPermittedUsers is available in FB_IotCommunicator for this purpose.

Configuration at variable level

It is also possible to assign authorizations for each variable. The iot.PermittedUsers attribute can be used for this purpose. This applies to both structures and individual variables.

At both device and variable level, the permitted users are specified comma-separated by a string. Further information can be found at FB_IotCommunicator and Attributes.
