Note

• You can operate a SIMATIC HMI together with a drive unit independently of an existing

control.

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.
