Post by tortilla on J1939 connection between two devices ^{CODESYS Forge talk (Post)}
Hey, 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). 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) I watched a few videos, worked with the documentation and worked with chatGPT 4o and was able to build the attached file. This part is about the device on 3.5.11: 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. I added the two devices in the CANbus in the J1939Manager and addapted the options like I've seen in the documentation. 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? Thanks in advance!

Post by fajean on Issue with library updates ^{CODESYS Forge talk (Post)}
We make heavy use of internally developed libraries, which are often nested on multiple levels. I routinely work simultaneously on several libraries along with a project that use them. I make changes to a library and immediately perform a download (online or otherwise) in the project. For the longest time, we had zero issue with this. But starting a good while back, with 3.5 SP19 I think, CODESYS started not noticing library updates in other instances most of the time. When the update is missed, the project sees no need to update the code, and any download ignores the new code. A "Clean all" does not solve the issue. But if I close and then re-open the project, then the new version is noticed and the download works. The other solution is saving the library to the registry multiple times (say, 20-30 times, less if lucky), and then at some point the project notices the changed library. I am now on SP21, and it is still not fixed. This is driving me mad, any tasks probably takes me double the time or more due to this problem. My colleague has the same problem on a separate computer. Is this a known issue? Is there a setting somewhere that changes how updates are checked? Thanks for any help!
