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 switch of the memory module (exception:

MM1xx memory module) 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 sync as well as 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 and can be changed via parameters/indexes, if required.
