CAN bus
All level and conductivity controllers and associated electrodes are interconnected by means of a CAN
bus adopting the CANopen protocol. Every item of equipment features an electronic address (Node ID).
The fourcore bus cable serves as power supply and data highway for highspeed data exchange.
The CAN address (Node ID) can be set between
1
and
123
.
The equipment 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 (e. g. controller and probe) acc. to the
table on page 21.
If the length of the CAN bus cable exceeds 125 m, use code switch
8
(Fig. 18) to change the
switch positions.
Note:
The baud rate must be identical for all items of euqipment!
For more information refer to the section
“Basic Settings – Code switch settings”.
