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 ( 189)
1) If you set the sync transmit/receive identifier manually, observe the use of the emergency telegram, since it has the same
COB-ID.
