I'm trying to create a J1939 message with a PGN equal to 130. But I couldn't determine how the ID is going to look like in order to get that exact PGN.
Can you please share a suggestion?
Thanks a lot

\$\begingroup\$ Isnt it just R=0, DP=0, PF=0x00, PS=0x82? (assuming you mean decimal 130) \$\endgroup\$– BeB00Mar 6, 2018 at 1:12

\$\begingroup\$ @BeB00 , No can you give the full 29-bit identifier then. ie: with 0x008200 would give PGN = 0x00 as from alumni.cs.ucsb.edu/~savior/convert-j1939-id-to-pgn.php \$\endgroup\$– The BeastMar 6, 2018 at 21:04

\$\begingroup\$ That calculator wont give you a PGN of 130. If that calculator is correct, then a value of 130 isnt possible. The calculator wont accept a PF of 0, which is required to get PGN=130 \$\endgroup\$– BeB00Mar 6, 2018 at 22:18

1\$\begingroup\$ In that case it might be 0x00000980, but I dont think these calculators are calculating the PGN properly, or else you cant have a PGN that low. It seems that the PGN always has 6 trailing 0's \$\endgroup\$– BeB00Mar 6, 2018 at 23:26

1\$\begingroup\$ Then I guess you cant have a PGN that low. Again, why do you want one? \$\endgroup\$– BeB00Mar 7, 2018 at 0:59

if 130 is in hex PGN=0x130, it means PDU Format is 1 and PDU Specific is 30, it depends on your option if your priority is 1 and Source Address is 1 your ID is 0x4013001. search j1939 frame on google for details
