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.
10.2.2.5 Monitoring: 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.
