The J1939 Plugin is an optional extension for the CANinterpreter and CANopen DeviceExplorer software tools. It provides functions to interpret and to send J1939 messages. Selected SPN values can also be displayed in a chart.
The payload of the PGN are interpreted. BAM and TP.CMDT messages can be interpreted on protocol layer but the extension is also able to show the payload of these messages.
Safety Header Messages, NMEA2000 messages and diagnostic messages are also interpreted as shown in the images above.
The J1939 transmitter is able to transmit various J1939 messages. These are:
- Standard PGNs <= 8 bytes
- Request PGN and Address Claiming
- Broadcast PGNs > 8 bytes by BAM
- some diagnostic messages
- J1939 CAM11/CAM21 messages
J1939 SPN Plotter (Chart)
The SPN data plotter (chart) can be used to record and to visualize selected SPN values. The recorded SPN values can be exported afterwards and the chart supports SPN in ‘normal’ 8-byte-message but also SPNs that are transmitted via BAM, CMDT or Fast.
