Basis für all diese Linux Produkte mit CODESYS ist Socket CAN- sprich wenn dein Adapter in Linux als Socket CAN verfügbar ist sollte es funktionieren. also zunächste mal sowas ausprobieren: sudo ip link set can0 up type can bitrate 500000 sudo ip -s -d link show can0 cansend can0 00065132#21.04.00.00.3E.80.50.00

make sure the PLC and the programming PC have IP addresses that are on the same subnet, you'll have to know the default address of the PLC or you may need to connect to it with a special cable and use a software tool to set the IP address.

Post by aconley on Static Code Analysis ^{CODESYS Forge talk (Post)}
I'm using CODESYS 3.5 SP16 Patch 6. I would like to incorporate static code analysis as part of our CI/CD pipeline. 1. Is there a way to execute the static code check from the command line or python script? 2. If you can't do it from the command line, is there a way to export the results from the application?

Hello, I'm coming to you today because I'm trying to make the baudrate and the slave number dynamic. I've tried the "updateComPortSettings" method on the slave device but it doesn't work and gives the "Modbus_COM_Port" an error. Can you tell me how you got this method to work? Thanks in advance for your help jérémy

Post by scrisp on Source code changes since last download ^{CODESYS Forge talk (Post)}
Why does CODESYS 3.5 show the message “Source code changes since last download” even though I did not create or modify any new variables? When I go online with the PLC, it detects changes and suggests synchronizing, but nothing was actually changed in the project. What could cause this and how can I fix it?

Good day, Currently running a project on a windows 10 IPC with TargetVisu. the project starts and runs but the TargetVisu screens will not accept a touch on the monitor but will work with a mouse. I have the option to use as a touchscreen active. I did not put my license on the device just yet. Do you have to have the license activated on the device before the TargetVisu will work via a touch? running Codesys v3.5 SP 19 Patch 6, 64bit. device is Codesys Control Win v3 X64

Post by farren on Codesys complains about matching versions ^{CODESYS Forge talk (Post)}
I'm building up a 2nd PC to match an existing developer PC. Installed the same SP and Patch levels but when I open a project that was created on the existing PC, Codesys complains that it's not the same version. Attaching a screenshot..... What else is there to match? Also, can all of the libraries that are on the existing machine be copied from it to the new machine and if so, how? (So I get the same versions) Which files/folders do I copy? Thanks! -Farren

Post by jnoyau on Visualisaion while in simulation ^{CODESYS Forge talk (Post)}
Hi all, Im new to Codesys 3.5, and am in the process fo making a visualisation i'd eventually export towards a Wago device. The issue I'm having currently is that when I compile and connect to the simulated program, my simulation won't launch. On the Visualisation tab, all I get is a text message (where previously there was my prepared visualisation) that says "The visualisation awaits a connection. Start the application" One thing to note: I work with Codesys 3.5 in french, so this is a rough translation. And a second: I'm not getting any errors nor warnings about the visualisation tab itself upon compiling Is there a step i'm missing after launching my simulation? Or would it be some really specific issue caused by the way I've set up my program? Thanks, J

Hey also ich soll mit CodeSys 3.5 ein Modell erstellen, welches ich dann später mit einem bestehenden Modell in Simit anbinden kann. In CodeSys steht das Modell mehr oder weniger und ich wollte jetzt mal ausprobieren, ob ich die beiden Modelle miteinander koppeln kann. Übern einen OPC UA Server hat das auch alles geklappt. Allerdings hängt es jetzt an den globalen Variablen. Wie gehe ich da am besten vor? Soll ich die Variablen in CodeSys anpassen oder gibt es da einen Trick? Vielen Dank schon einmal im Voraus!

Ciao damian177, provo a chiederti un'informazione. Sul mio progetto Codesys(ver.3.5 SP17) non è visibile l'oggetto "Data Source Manager". Il PC con il progetto Codesys(client) è collegato via rete TCP ad un PLC Siemens1200(server). Sul PC con Codesys ho installato UAexpert(client) e riesco a vedere le variabili del PLC1200. Riesci ad aiutarmi a capire come mai non è visibile l'oggetto "Data Source Manager"? Molte grazie

Post by rpostwvu on Shared Memory Access Issues ^{CODESYS Forge talk (Post)}
I got the shared memory example. I'm pretty sure I'm successfully created a memory space, CreateResult returns 18. szName:='CodesysDataShare'; hShm := SysSharedMemoryCreate(szName, 0, ADR(uxiSize), ADR(CreateResult)); I'm trying to access this memory with a C# application, but I get "Unable to Find Specified File". I suspect that Codesys and/or Visual Studio code alters the name I choose? Being in Windows, I cant find a way to see the mapped memory list. ~~~ using (var mmfRead = MemoryMappedFile.OpenExisting("CodesysDataShare",MemoryMappedFileRights.ReadWrite)) ~~~

Post by wbj0t on tool 'update raspberry pi' unavailable ^{CODESYS Forge talk (Post)}
Doesnt matter. I have installed sp20 with latest RP 4.13. Same problem. Anyway My large project in RP 4.10 and SP 19 and I need these versions and use same installation programm for Codesys IDE and RP4 package. I did install again, because my SSD broke and now cant update raspberry... I dont know how to translate correctly project to newest version - there are 52769 errors and incompatabilities: after updates libraries anyway some errors still because of devices... I found solution with .deb file from raspberry package - dont need IDE anymore for update raspberry.

Post by mavitia on Application based license problem - Modbus TCP ^{CODESYS Forge talk (Post)}
I am running ubuntu on a raspberry pi, and installed an application based license Control Basic M on it, it runs a demo program fine, does not timeout etc. however, when I add a modbus TCP device, I start getting errors: <Entry severity="error" component="CmpApp" user="nobody" timestamp="12/18/2023 3:49:42 PM" infoId="24">Online change denied. Application Application is in exception state!</Entry> <Entry severity="error" component="CmpApp" user="nobody" timestamp="12/18/2023 3:49:42 PM" infoId="68">Download failed: Application=Application</Entry> <Entry severity="exception" component="CmpApp" user="nobody" timestamp="12/18/2023 3:49:41 PM" infoId="0">Application app=Application has invalid license metrics!</Entry> the modbus tcp slave runs, and the counter ticks up, however, when I call the variables on the %IX0.0 in my program, and try to upload the changes, I am getting the error messages which stop the program as far as I understand, the application based, M includes 2 fieldbus instances, but on the other side is fairly new, anything obvious I am missing out here?

Hi, You can give a try it by adding "Codesys.exe" in the "Exclusions > Process" section of the Windows Security Center or your antivirus program. I hope it works for your situation. Antivirus programs check many things during both the installation or startup of an application, and may be slow down or block some functions. Regards Imdat

Ich hatte das ganze schon am laufen, sollte dann ein Firmwareupdate durchfuehren (auf die neuste moegliche). Das Firmwareupdate konnte ich auf 03.10.08(22) ist sauber durchgelaufen, die Firmware laeuft auch noch wenn die runtime aufgegeben hat. bekomme die runtime nur dann wieder zum laufen, wenn ich den ganzen controller reboote.

Hallo Forum Hat jemand Erfahrung mit dem Optimalem anpassen der Position und Grösse der Visualisierungselemente? Bei uns funktioniert in der Codesys 3.5 SP20 nur die Anpassung auf der x-Achse mit (Container.Width - Visu.Width). Die y-Achse wird jedoch mit (Container.Height - Visu.Height) nicht beeinflusst. Wir haben dies nach dem Beispiel von Codesys "Position und Größe optimal anpassen" umgesetzt und keinen Erfolg. Besten Dank für eure Hilfe.
