9.1.2 Change the Node ID and bit rate
The device supports several options how to change the
The device is delivered with the Node ID 32 and a bit rate of 125 Kbits/s.
Each Node ID must only be assigned once in the CANopen network. If a
Node ID is assigned several times, malfunction in the CANopen network
will result.
Change the Node ID and bit rate in the object directory
The Node ID is entered in the object directory in the objects 0x20F0 and 0x20F1.
If the two values are identical, the setting is stored and is active after a software
reset of the device. Values between 1 and 127 may be used as Node ID.
The bit rate is entered in the objects 0x20F2 and 0x20F3. If the two values are
identical, the setting is stored and is active after a software reset of the device.
The following values may be used as bit rate:
Value
Bit rate
0
1000 kBits/s
1
800 kBits/s
2
500 kBits/s
3
250 kBits/s
4
125 kBits/s
5
100 kBits/s
6
50 kBits/s
7
20 kBits/s
If a master is used in the CANopen network for central storage of
parameters, the changed values for Node ID (0x20F0 and 0x20F1) and bit
rate (0x20F2 and 0x20F3) must be additionally entered in the master.
Otherwise the values will be reset during each start of the CANopen
network.
