Operation
Applying SAE J1939 protocol
The CS 1939 has a CAN 2.0B port with access to the SAE J1939 log.
Whenever the CS is switched on, it sends an "Address Claiming" message to
share its name and address with the other participants. The measurement
values are not transmitted cyclically but rather called up by the PGN 61184
on request.
