J1939 Source Address Claim
Chris Litwin 4 months ago in IQANdesign • updated by Gustav Widén (System support) 4 months ago • 3
How does a master module using the J1939 "Address Claim" property respond to a request for address claimed message (PGN 59904) from an outside controller? Does the outside controller need to be built into the application? Will the IQAN controller respond to the broadcast request and a controller specific request?
I have a 3rd party system that is unknown at design time that requires address claim messages.

If the Address claim property is set to Yes on a J1939 bus, the IQAN master will try to claim its address at startup and respond to request for address claim. It responds to requests sent to its SA, and those sent to the global address 255.
If this property is set to No, the IQAN master will neither attempt to claim its address at startup, nor respond to request for address claim.
In a multi-master system, the IQAN masters will also claim J1939 addresses on the Diagnostics bus. The addresses claimed are starting at the Diagnostics bus property "J1939 start address".
Thank you, Gustav.
