)
Note!
System bus (CAN)
The ECSxA... axis module can communicate with a higher−level host system
(PLC) or further controllers via both CAN interfaces (X4 or X14).
MotionBus (CAN)
The "MotionBus (CAN)" term expresses the functionality of the CAN interface
X4 in case of ECSxS/P/M... axis modules, where communication takes place
using a higher−level host system (PLC) or further controllers exclusively via the
X4 interface. Interface X14 (CAN−AUX) is exclusively used for parameter setting
and diagnostics.
)
Note!
In case of ECSxS... axis modules
only the parameter data channels (SDO) are supported for the system bus
(CAN) ˘ interface X14 (CAN−AUX).

Tip!
More detailed information on the CAN bus can be found in the appendix of
this documentation (
¶ 441).
8.1.1 Setting CAN node address and baud rate
For the CAN interfaces X4 (MotionBus) and X14 (system bus), the CAN node address and
the baud rate can be set via the DIP switch S1 or via codes.
ƒ The (address) switch 1 serves to define whether the set CAN node address shall only
apply to the interface X4(MotionBus) or for both interfaces X4 (MotionBus) and X14
(system bus).
ƒ If one of the (address) switches 2 ... 7 of the DIP switch is switched on (ON), and the
low−voltage supply is connected, the setting of the DIP switch is evaluated and
written into C0350/C2450 (CAN node address) and C0351/C2451 (baud rate).
ƒ If the (address) switches 2 ... 7 are switched off (OFF), the switch position is not
evaluated. The settings from C0350/C2450 (CAN node address) and C0351/C2451
(baud rate) are accepted.
ƒ The settings for the baud rate with the switches 8 ... 10are only written into C0351
(X4 CAN) when the low−voltage supply is switched on.
ƒ The baud rate for X14 CAN−AUX can only be set via C2451.
