<div class="markdown_content"><p>Hey,<br/> I'm pretty new to CoDeSys so I don't know a lot of things yet. I have to create a connection between two devices (CANbus - J1939 connection). <br/> The idea for now is to send a message from one to another (one operates on 3.5 SP11 the other one on 2.3)<br/> I watched a few videos, worked with the documentation and worked with chatGPT 4o and was able to build the attached file.<br/> This part is about the device on 3.5.11:<br/> I'm using the J1939LocalECUDiag, TransmitParameterGroup, TransmissionTrigger Function blocks to send the message but my TransmitPG.xBusy / .xDone never turns to True and therefore my message is not sent while TransmitPG.xExcecute is True.<br/> I added the two devices in the CANbus in the J1939Manager and addapted the options like I've seen in the documentation.</p> <p>Can anyone explain what's wrong with my code in this casse or give me advices how to properly create a connection between my two devices? </p> <p>Thanks in advance!</p></div>
