8.4.3 CANopen address and baud rate setting
The VS18/VS26 CANopen valve island address can be set within the range 0 to 99 (rotary
switch) resp. 127 (software). To set the address, use the selector switches accessible by
removing the securing screw and lifting the hinged cover of the address switches. The two
rotary switches allow an address range of 1 to 99. The valve island needs a power reset to
accept a new address. When position 0 is selected on both switches the address may be set
through software via a capable master.
Default address = 127
Changing the address of the node via software:
Using a CANopen configuration tool connected to the network, the address of each node maybe
changed by the following method:
Send an SDO Telegram command to the node at SDO index 2100h containing the new node
address, valid range 1-127. View example of SDO message below
