SIMOTION, SINAMICS S120: Safety Integrated Extended Functions - Failsafe drives on SIMOTION D435 with PROFIsafe control via PROFIBUS slave-to-slave communication
A system equipped with SINAMICS S120 drives is controlled by a SIMOTION D435. Various safety functions must be used within the system.
The SIMOTION does not comprise any safety functions. It uses the extended safety functions integrated in the SINAMICS S120 drives.
These drive-integrated safety functions shall be controlled by the F-CPU using the PROFIsafe telegram via PROFIBUS slave-to-slave communication. The safety signals acquired via a failsafe digital input module are processed by the F-CPU and transferred to the drives using the above-mentioned telegram. In this case, the SIMOTION serves as the PROFIBUS master and the F-CPU as I slave. The PROFIdrive communication is established between the SIMOTION and the SINAMICS, the PROFIsafe telegrams are exchanged between the F-CPU and the SINAMICS via the PROFIBUS slave-to-slave communication.
This functional example is based on the SIMOTION D435 training case (6ZB2 470-0AE00), the SINAMICS training case (6ZB2 480-0BA00) and the SAFETY training case.
