Node address (node ID)
Every node of the system bus network must be assigned to a node address (also called node ID)

within the valid address range (1 ... 127) for unambiguous identification.

• Assigning a node address more than once within a network is impermissible.
• The own node address can be configured via the DIP switches or via code

C00350

.

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 the basic SDO channel (SDO1) are

defined in the CANopen protocol and cannot be changed.

• The basic identifiers of the PDOs are preset in the Lenze setting according to the "Predefined

Connection Set" of DS301 V4.02.

Tip!
If required, the identifiers of the PDOs and the identifiers for the sync telegram can be

changed via parameters/indices.

If you set the sync identifiers manually, observe the use of the emergency telegram, since it has the same COB-ID.
