Note
● 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 function 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.
