Identifier assignment
The system bus is message-oriented instead of node-oriented. Every message has an unambiguous

identification, the identifier. For CANopen, node-oriented transfer is achieved by the fact that every

message has only one transmitter.

• The basic identifiers for network management (NMT) and sync as well as the basic SDO channel

(SDO1) are defined in the CANopen protocol and cannot be changed.

• In the Lenze setting, the basic identifiers of the PDOs are preset according to the "Predefined

connection set" of DS301, V4.02 and can be changed via parameters/indexes if required.

Identifiers of the process data objects

1) If you set the sync transmit/receive identifier manually, observe the use of the emergency telegram, since it has the same

COB-ID.
