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.

10.2.2.5Monitoring: telegram failure

Description

After a telegram failure and a monitoring time has elapsed (t_An), bit r2043.0 is set to "1" and alarm A01920 is output. Binector output r2043.0 can be used for an emergency stop, for example.

After a delay time has elapsed (p2044), fault F01910 is output. Fault F01910 triggers fault response OFF2 (pulse inhibit) for the supply and fault response OFF3 (emergency stop) for SERVO/VECTOR. If no OFF response is to be triggered, the fault response can be reparameterized accordingly.

Fault F01910 can be acknowledged immediately. The drive can then be operated even without PROFIBUS.
