User roles and related access authorization

The two user roles "Operator" and "Maintenance" have different write access to the
parameters if the customer defines a user-specific access code. This protects the device
configuration via the local display from unauthorized access →  158.
Defining access authorization for user roles
An access code is not yet defined when the device is delivered from the factory. Access
authorization (read and write access) to the device is not restricted and corresponds to the
"Maintenance" user role.

status parameter. Navigation path: Operation → Access status
