8400 HighLine | Parameter setting & configuration
System bus "CAN on board"
Implemented CANopen objects
Example
Parameter data channel 2 of the controller with node address 4 shall be activated.
For this, bit 31 must be set to "0" (≡ "SDO is valid") in subindices 1 and 2 of the object I-
1201.
The master must send the two "write request" commands to the nodes via the basic
SDO channel.
Identifier calculation
Identifier (COB-ID) = basic identifier + node address (node ID)
Basic identifier SDO2 from master to drive: 1600 (0x640)
Identifier = 0x640 + 0x4 = 0x644
Basic identifier SDO2 from drive to master: 1472 (0x5C0)
Identifier = 0x5C0 + 0x4 = 0x5C4
Resulting data (data 1 ... data 4)
[10-7] Data telegram assignment for subindex 1
[10-8] Data telegram assignment for subindex 2
User data assignment
[10-9] User data assignment for writing to subindex 1
[10-10] User data assignment for writing to subindex 2
