Node-ID
CAN Bus
All level and conductivity controllers and associated electrodes are interconnected by
means of a CAN bus using the CANopen protocol. Every item of equipment features
an electronic address (node ID). The four-core bus cable serves as power supply and
data highway for high-speed data exchange.
The CAN address (node ID) can be set between 1 and 123.
The NRS 1-42 is configured at our works and ready for service with other GESTRA
system components without having to set the node ID.
If several systems of the same kind are to communicate in one CAN bus
network, be sure to assign one node ID for each individual system component.
Refer to pages 23 and 24 for more details.
