SAE J1939:Include Destination Address in PGN

Last Modified: September 16, 2019

Include the J1939 destination address (PDU1 PS field) when matching received frames to database frames.

When set to True, this property instructs NI-XNET to include the destination address when extracting the parameter group number (PGN) from the frame. This allows the same PGN sent to different destination addresses to be handled by separate input sessions.

This property applies to only the CAN J1939 application protocol.

Data type: datatype_icon

Long Name: SAE J1939:Include Destination Address in PGN

Class: XNET Session

Permissions: Read/Write

Incoming J1939 frames are matched to an XNET database by the PGN of the frame. When receiving PDU1 frames, the destination address of the frame (J1939 PS field) is ignored when calculating the PGN, in accordance to the J1939 specification. This causes an XNET session to receive all frames that share the same PGN, making it difficult to distinguish destinations for traffic.

When set to True, this property instructs NI-XNET to include the destination address when extracting the PGN from the frame. This allows the same PGN sent to different destination addresses to be handled by separate input sessions.

This property may be set at any time. When set after session start, it will not affect frames already received.

The SAE J1939:Include Destination Address in PGN property is valid only for input sessions. It is not valid for stream sessions. This property affects all frames in a session.
