In the WinCC help section about the OPC UA server, the Analog Item object is mention, but also that it is currently not supported.
But then a detail description of it follows, including a mapping of the EngineeringUnits to a _common.._unit config, that apparently exists.
But I cannot find any more information about such a config.
As far as I know the unit is suffixed on to the dp description and accessed with dpGetUnit() and dpSetUnit() but that the database has no explicit config for this.
Does it mean that the whole object is not supported?
Is it maybe planned for the future that the attributes described in the WinCC OA Config column will be mapped to those in the OPC UA column?
