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 2-40 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 27 and 28 for more details.
Node ID
Basic Adjustments
First and second control equipment
It is possible to operate the level switch NRS 2-40 together with a second level
switch NRS 2-40 when 8 instead of only 4 switchpoints are required.
The second level switch is termed “second control equipment” and must be
ordered separately.
The NRS 2-40 can also be operated together with the level controller NRR 2-40
as “second control equipment”.
The standard equipment NRS 2-40 is termed “first control equipment 1”.
Be sure to assign different node IDs for NRS 2-40 (first control equipment),
additional NRS 2-40 (second control equipment) and NRR 2-40 (controller)!
The name plate of the NRS 2-40 is marked “Control equipment 1” or
“Control equipment 2”.
