J1939 Comunication Between Master And Slave

Carl 7 years ago in IQANdesign • updated 7 years ago • 10

Hi Guys,


We have a MC42 and an MC41 on a machine. MC42 is connected to the J1939 Channel.

We would like to communicate some limited J1939 messages between the master and slave. How do we do it?

Have a look on the file "Multi master with J1939.ida4" in the solution library in your documents: like this C:\Users\......\Documents\IQAN Files\Solution Library

Do I have to hard wire the diag CAN line to the J1939 CAN line?

Hi guys,


Still no luck. Is there no way to get a slave to send a J1939 message on the bus without hardwiring it?

We need the slave to send a message that the master will respond too and it just doesn't work???

You can separate them..

..but also have diagnostic & J1939 shared


...not sure if this of any help
