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!

Thanks Edwin. I have reviewed the example and I'm doing basically the same when calling the methods. The recipe files are in the right directory. Everything looks okay but simply it doesn't work. May migrating to Codesys 3.5.20 will solve this?

Post by hwopereis on SFC Action problems ^{CODESYS Forge talk (Post)}
Only logged in to agree with the above. So counter intuitive. Why does an associated action force the variable when the step it is associated to is not active? Makes no sense at all, is terrible to debug and costs a lot of time. Such as shame.

Post by sigurdrb on send appliaction files to wago plc (codesys 3.5) via ssh ^{CODESYS Forge talk (Post)}
Hi, I was hoping I could send the two files "application.app" and "application.crc" directly to the directory "/home/codesys/PlcLogic/Application" instead of logging into the device with codesys, downloading the program to the controller and then do the "create boot application", so it will reboot with the correct program running. I think i also need to edit the file "eRUNTIME.cfg" located in the "/home/codesys/ folder, because when I create the boot application from the codesys IDE, these lines are added to the file: [CmpApp] Application.1 = Application [SysFileMap] /home/codesys/PlcLogic/Application/Application.app=0x212520, 0x2DBC747E, 2DBC747E.app I think the "eRUNTIME.cfg" file is the same as CODESYSControl.cfg I also dont know the purpose of the hexadecimal numbers etc. that is generated. When I tried to replicate what codesys was doing, I placed the same files in the same folder as when codesys generated the boot file. And also added the lines in the eRUNTIME.cfg file: [CmpApp] Application.1 = Application [SysFileMap] /home/codesys/PlcLogic/Application/Application.app The controller did not boot up with any program, so my method did not work at all. I guess these lines tells the controller to run an application and where to find it? Could any of you help me with the best way to get the compiled program to the controller without using codesys or wago-software?

Hey Guys, could you give a explaination of how to change the g_udiMaxPacketSize from 6000 to 100000 and g_udiMaxPayloadSize from 4096 to 80000 ? When I go to the library the parameter is not editable. I would really appreciate it :) Kind Regards

Post by paulg on CODESYSControl_User.cfg - link to documentation? ^{CODESYS Forge talk (Post)}
Is there somewhere in the Codesys help files that generally details what configuration options are available for this file, and what details it logs regarding the configuration file? Or is that going to differ by libraries being used? Thanks!

Post by fizzy-bubblech on 3.5 P20 hangs - no response ^{CODESYS Forge talk (Post)}
Colleagues, i have the same problems. At the current time, I have to use the new version of the Codesys (3.5.20.10) + Control for Linux SL 4.11.0.0, but it works unstable : theree are a lot of freezes and not-respondings. I tested this on different projects: those that were created in the current version of the project, and those that were migrated from other versions of the development environment. Compiling a project without connecting to a controller is fast enough. The first downloading of the code into the controller, too. But as soon as you need to make edits and download a new code problems begin. Codesys "freezes" at the "Generation code" stage for 15-20 minutes. And only after that time loads the code into the controller. Previously, we used version 3.5.17.60 + Control for Linux SL 4.7.0.0. The process took 1-2 minutes. Do you have any ideas how can i fix it? I will be grateful for your answers.

yes sure. Thx for your support! This is the Codesys project stripped down only to my EtherCat and OneWire Configuration. The Project now contains only one OneWire Master on GPIO4.

Post by eschwellinger on Two OneWireMaster on one Raspberry PI 5 ^{CODESYS Forge talk (Post)}
the project has only one OneWire Master - so if you add the setting "PlaceholderFilePath.2=/sys/devices/w1_bus_master2, $OneWire2$ to the config file it will fail and the Ethercat task will be blocked by the OneWire Master readings?
