Ethernet operation
For this version CAN bus wiring is not required at all (cf. Fig. 6.43). Th e communication is handled exclusi-
vely via Ethernet. All CANopen messages and services (PDO, Emergency, NMT etc.) are managed.
Redundant operation
Th e special feature of this version (Fig. 6.44) is that e.g. service data (via SDO) can be exchanged via Ether-
net while process communication is done via the CAN bus. Th e SDO transfer with the PC/IPC does not re-
ach the CAN bus which is not disturbed (e.g. synchronous motion). In order to change the operation mode
the gateway mode has to be deactivated in each device (object 0x2FB2, sub index 12), because otherwise
the devices would send the messages to each other continuously. Process data communication is decoupled
completely from the Ethernet in this case. All other CANopen messages and services (PDO, Emergency,
NMT etc.) are not switched through from the CAN bus to the Ethernet side (and vice versa).
