4.2 CAN

4.2.1 CAN Interface

The physical layer is designed according to ISO 11898-2. The CAN bus signals are electrically isolated
from the other signals via a digital isolator and a DC/DC converter.

Fig. 11: CAN Interface

The CAN interface can be connected via the CAN connector or optionally via the InRailBus. Use the
mounting-rail bus connector of the CBX-InRailBus (CAN-CBX-TBUS), see order information
(page 102).
