Node-ID Setting
3
The rotary encoding switches are marked with H for High (more
significant digit) and L für Low (less significant digit).
BL20-GW-CANOPEN:
The L switch is used to set L X 16
0
(L = 0 to F).
The H switch is used to set L X 16
1
(H = 0 to F).
BL20-GWBR-CANOPEN:
The L switch is used to set L X 10
0
(L = 0 to 9).
The H switch is used to set L X 10
1
(H = 0 to 9).
See Chapter 6
, "Maximum System Extension", Page 6-2.
Attention
A maximum of 127 Node-IDs (1 to 127) can be assigned in a
CANopen structure. Each Node-ID can only be assigned once in the
complete bus structure.
The Node-ID 000 must not be assigned. It is reserved for telegrams
that are directed to all the other bus nodes.
Note
The NODE-ID switch on the BL20-GWBR-CANOPEN can be used
to assign Node-IDs from 1 to 99!
Note
After setting the Node-ID, the protective cover over the switches
must be closed again.
Note
BL20 does not support the assignment of Node-IDs across the bus
network.
