You can operate a SIMATIC HMI together with a drive unit independently of an existing
controller.
A basic "point-to-point" connection can only be established between two nodes (devices).
The "variable" HMI functions can be used for drive units. Other functions cannot be used
(e.g. "messages" or "recipes").
Individual parameter values can be accessed. Entire arrays, descriptions, or texts cannot
be accessed.
