Establishing / changing node ID
If several identical systems are to communicate in a CAN bus network, allocate a different node ID for
each system (e. g. limiter, controller, etc). In most cases it is sufficient to commission the equipment
with the default factory settings.
To set the code switch 8 remove the lower terminal strip 9.
Attention
n We recommend that you commission the CAN bus devices with the default factory
setting.
n Do not use a node ID for more than one piece of equipment in the CAN bus system.
