7.2 Data transfer via CAN
[7-1] Parameter data transfer via CAN
Parameter data are transmitted via the CAN bus as so-called "Service Data Objects (SDOs) and are
acknowledged by the receiver. The SDO enables read and write access to the object directory.
Indexes (e.g.
I-1000 ) provide for access to parameters and functions of the device, which are stored
in the object directory. In order to be able to transfer SDOs, the information contained in the user
data must comply with the CAN-SDO protocol.
CANopen parameter channels
The communication module is provided with two parameter data channels.
In the Lenze standard setting, both channels are activated.

Note!
Compatibility with CANopen
Switch off the second parameter data channel via code C1200 in order to establish
compatibility with CANopen.
