2.5.7 Interface
Logic
The interface logic forms the interface to the communication controller of the user
electronics. Three operating modes are possible:
Without galvanic isolation
If galvanic isolation of the bus interface (MAU) from the application-specific
electronics is not required, the send or received signals with GIM = L on the
interface are passed on without any processing and switched through to the user
electronics. The output level of RxA and RxS is adapted over the interface and
application voltage VREG.
Conventional isolation with optocouplers
To achieve galvanic isolation of the lines for data and associated signals, various
isolating components and circuits can be used. One common method is to provide
an optocoupler for each of the signals TxS, TxE, RxS and RxA.
Power-saving isolation with optocouplers
The SIM 1-2 also provides the option of a power-saving galvanic isolation with only
2 optocouplers.
