13.4 Communication with MotionBus/system bus (CAN)
Note!
In case of ECSxS... axis modules
only the parameter data channels (SDO) are supported for the system bus
(CAN) ˘ interface X14 (CAN−AUX).
For communication between the components of the drive system the axis modules
ECSxS... have two CAN interfaces:
ƒ Interface X4 ("CAN")
MotionBus (CAN)
For communication with a higher−level host system (PLC) or further controllers
The data is exchanged via process data channels and parameter data channels.
Parameter setting/diagnostics via code range C03xx
ƒ Interface X14 ("CAN−AUX")
System bus (CAN)
PC interface/HMI for parameter setting and diagnostics
Interface to a decentralised I/O system
The data is exchanged via parameter data channels only.
Parameter setting/diagnostics via code range C24xx
The communication is effected via data telegrams.
