Operation
6.5 Connecting to the AS-i master via AS-Interface
Note
The signals of the output cells can be included in the logic again through input cells.
Example
The MSS 3RK3 Advanced simulates a non-safety-related AS-i slave on the AS-i bus. The signals
from and to the master can be fed into and processed in the logic of the MSS 3RK3 Advanced.
The sensor signals from the simulated, non-safety-related AS-i slaves to the master are output
to the AS-i bus through the output terminals in the logic.
