Hello,

I'm trying to manage two LIN latches with two CAN messages.

The feedback messages are ok but when I'm trying to control the latches, the latches don't follow the commands...

I think I have the correct schedule time and publisher and subscriber ID's.

Thanks for your help.

Hi,

what kind of CAN messages did you send to the PCAN-LIN? Please note that you have to use an offset of 0x40 for the CAN ID to change the publisher data. In your case you have to send a CAN ID 0x04 +0x40 +CAN-ID Offset (in your case 0x48E) = 0x4D2 with dlc 2 to change the publisher data of LIN ID 0x04.

Hi Michael,

Yes, I did it and that's not the problem. I think the problem is with the timing or the counter... With direct LIN messages, my configuration is working fine but when I add the PCAN-LIN... The latches are not following my commands...

The frame configuration is OK and the scheduler also.It Is following the .ldf table...




Any other idea?

Thanks a lot!
Abel.

Hi,

do you have a ldf of your LIN system, to see the length code and checksum type of the used LIN frames?

Hi Michael,

Yes! Take a look:



What do you think? I'm going to record a log with PLIN.

Thanks,
Abel.

unfortunately I can't see any baudrate settings in your screenshot. Please be sure that you disable the publisher from your other LIN device, while using PCAN-LIN. It is not possible that there are two devices setting the same publisher data.

Hi Michael,



Baudrate is 19.200 Kbps.
I only have one Master device (PCAN-LIN) and two slave devices. Please, take a look to the log with PLIN-USB.
I do not know why PCAN-LIN is not working...

Thanks again!
Abel.

Hi,

do you have a ldf of that system, to see which frames are publisher and which are subscriber. This is not clear for me from your screenshots.

Hi Michael,

Please find attached the ldf file.

Thank you!
Abel.

Hi,
