Example

Parameter data channel 2 of the controller with node address 4 is to be activated.

For this purpose, bit 31 must be set to "0" (≡ "SDO is valid") in the subindexes 1 and 2 of

the

I-1201

object.

The two "write request" commands must be sent from the master to the nodes via the

basic SDO channel.

Calculation of the identifiers

Identifier (COB-ID) = basic identifier + node address (node ID)

Basic identifier SDO2 from the master to the drive: 1600 (0x640)

Identifier = 0x640 + 0x4 = 0x644

Basic identifier SDO2 from the drive to the master: 1472 (0x5C0)

Identifier = 0x5C0 + 0x4 = 0x5C4

Resulting data (data 1 ... data 4)

[6-11] Assignment of the data telegram for subindex 1

[6-12] Assignment of the data telegram for subindex 2

Assignment of the user data

[6-13] Assignment of the user data for writing to subindex 1

[6-14] Assignment of the user data for writing to subindex 2
