Post by smartcoco on Request a dark mode for CODESYS ^{CODESYS Forge talk (Post)}
CODESYS IDE is not a modern IDE. Its interface is ugly, its operation is not user-friendly, its functions are lacking, its feedback is slow, and its development is not good enough. In fact, CODESYS is a helpless choice under the current situation. But this situation will not last long. For example, SIMATIC AX is a strong competitor of CODESYS, which is more open and inclusive.

Hello, I was browsing the "CODESYS Virtual Safe Control for Linux SL" documentation page, and it says the following : For more information about the development of safety-critical applications with CODESYS, see: * Safety Manual H1 – SafetyManual.pdf, which is stored in the directory ../<user>/CODESYS Virtual Safe Control Linux SL/Delivery/Manuals</user> What does this path refers to ? I can't find it in CODESYS installation directories. Best regards

Post by timvh on Codesys Runtime Devie Password ^{CODESYS Forge talk (Post)}
This has been moved because of security reasons. But it depends on how you start CODESYS where the project files are located (at least for Control Win from SP20). 1) If you start it through the sys tray icon, you start it as a service and the files will be located in: C:\Windows*System32\config\systemprofile\AppData\Roaming\CODESYS... (or C:\Windows*SysWOW64**\config...) 2) If you start it as a user, e.g. with a shortcut to the runtime, you can find it in: C:\Users\<your user="" name="">\AppData\Roaming\CODESYS...</your>

Post by alex2 on How to uninstall SVN module ^{CODESYS Forge talk (Post)}
Hello, At work, I use Codesys V3.5 SP10. I wanted to run some tests with the SVN module, which I kept installed (without actually using it in the end). However, when I tried to launch Codesys today, I was informed that a license was missing. I suspect that this is due to the SVN module. Could you tell me how to uninstall it without launching Codesys? (as i cant proprerly start Codesys without the license) Thank you in advance.

When exporting a Logical Device or Logical Exchange GVL using the native XML export functionality of the CODESYS Script API, I encounter the following error upon re-import: "Error in IEnumeratorOfTWrapper. Current. Could not cast: System.String in System.Char" I am using CODESYS V3.5 SP21 Patch 2. Is there a known solution or workaround for this issue? Notably, importing the same XML file through the CODESYS Engineering IDE's menu import works without error.

Post by timvh on How to correctly create a device descriptor (.devdesc.xml) for a custom Linux ARM64 PLC in CODESYS 3.5.21.20? ^{CODESYS Forge talk (Post)}
If you are a vendor of controllers and want to have your own CODESYS Runtime on your device, then you need to contact the CODESYS Sales team and ask for the runtime Toolkit. For resellers of CODESYS devices, this can be interesting. If it is only for a few devices, then why not just take the standard runtime?

Post by hismoon on CodeSys SVN funktionert nicht ^{CODESYS Forge talk (Post)}
Das CODESYS SVN AddOn hat Minimal-Versions-Vorgaben. In SP9 funktioniert wohl die neueste SVN Version nicht. Da mal am besten im Store auf die Release Notes auf der Download-Seite schauen. Da steht meistens, ab wann Minimal-Versionen erhöht wurden. (Required CODESYS version) V4.2.6.0 vom SVN AddOn scheint die letzte zu sein, die mit SP9 offiziell funktioniert. Eigentlich sollte das der CODESYS Installer / Package Manager abfangen, aber hmm.

Post by timvh on History of Alarms ^{CODESYS Forge talk (Post)}
It is most likely related to the existing alarm log files in the Control Win. Depending on how you start up the Control Win, you can find the files in: C:\Users\<user name="">\AppData\Roaming\CODESYS\CODESYSControlWinV3x64\<unique id="">\PlcLogic\alarms\ Or C:\Windows\System32\config\systemprofile\AppData\Roaming\CODESYS\CODESYSControlWinV3x64\<unique id="">\PlcLogic\alarms\</unique></unique></user> Delete the files in this folder, download your project again and start the application. PS, if you have an older version of CODESYS, the files are in: C:\ProgramData\CODESYS\CODESYSControlWinV3x64\<unique id="">\PlcLogic\alarms</unique>

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?

Post by jinlee on Symbol Configuration ^{CODESYS Forge talk (Post)}
Hi guys, I am working on an old project which using Codesys v2.3 talks to Beijer's screen TA150 (IX-Developer 2.20). Codesys v2.3 is different with 3.5 and Ecockpit. I know how to import the symbols from PLC to HMI for Codesys 3.5 and Ecockpit. However, I do not know how to do it on Codesys v2.3. I know that I can make excel sheet to import and export from the HMI and add whatever I want based on PLC. However, is there any quicker way of doing this? So that I can directly import the symbols (tags) from PLC (Codesys 2.3 to HMI).

Post by micik on Start Codesys project and then execute python script from command line ^{CODESYS Forge talk (Post)}
Hello, by searching the forum, I have found an example of batch script that can be used to start codesys projct by temporarily setting env variables. However, I'm not sure how to modify this to start Codesys 3.5.20 and whether or not I need to specify "profile" with Codesys version at all. @echo off SET PROJECT=D:\TestScripts\Data\OnlineTest.project SET VARIABLES=POU.testint,POU.testoutput start /wait CoDeSys.exe --profile="CoDeSys V3.4 SP3" --noUI --runscript="D:\TestScripts\Forum_Environment.py" I have tried the following just to open the test project: SET PROJECT=C:\TEST\Example.project start CODESYS.exe --profile="CODESYS V3.5 SP20 Patch 2" But I'm not sure how to specify this project to be open after py script is executed. The py script should first add required library to the project and then project should be open.

Post by timvh on Profinet fault with codesys control V3 - Receive packet error ^{CODESYS Forge talk (Post)}
Are you using the Control Win SL (installed together with the development environment of CODESYS)? If yes, you might want to consider using the CODESYS RTE instead. This has real-time capabilities (running on separate core(s)). But to be able to use this, you have to install the CODESYS Ethernet driver for your network interface to be able to let the RTE access the network port also in realtime. See: https://store.codesys.com/en/codesys-control-rte-sl-bundle.html https://content.helpme-codesys.com/en/CODESYS%20Control/_rtsl_windows_rts_v3.html PS, I haven't tested this myself yet, but you could try to use the SetCommunicationState method of the Profinet controller to see if you can reset and start the bus communication: result := PN_Controller.SetCommunicationState(eRequestedState := DED.DEVICE_TRANSITION_STATE.START); PS, if you are located in the Netherlands or Belgium, we could also provide the license(s) for you.

Post by timvh on Codesys v3.5.22.10 - Fail to create a project Archive ^{CODESYS Forge talk (Post)}
There is an issue with adding the visu styles to the archive with Visu add-on 4.9.0.0 and 4.9.1.0. When you create the projectarchive disable the option to add the style(s) to the archive. CODESYS support informed me it will be fixed with visu add-on 4.10.0.0 (May 26th 2026). An alternative is to start CODESYS as Administrator. Then it will work with styles as well. You could start CODESYS as Administrator by first opening the CODESYS Installer. At the bottom you can select to start the Installer as Administrator. If you do this and then start the CODESYS version from this installer, it will work.

Post by erictur on CODESYS Control for Linux ARM SL (32 bit) on Moxa UC-3100 IPC ^{CODESYS Forge talk (Post)}
UC3100 comes with Arm Cortex-A8 1 GHz and belongs to Moxa Industrial Linux 1 (Debian 9) for Arm-based Computers. I tried to install the CODESYS Control for Linux ARM SL (32 bit) on Moxa UC-3100 IPC. Unfortunately, the Third-party requirements: - libc >= 2.27 (required by CodeMeter Runtime) of the CODESYS Control for Linux ARM SL cannot be met on the Debian 9, which comes with glibc 2.24. I read the post by @johnlee (Getting Start with Codesys Control for Linux SL) (https://forge.codesys.com/forge/talk/Runtime/thread/0a515ced3f/). Where he discusses installation of CODESYS Control for Linux ARM SL on Debian 9. There was CODESYS Linux runtime v3.5.14 availble and it was successfully intalled on the Debian 9. However, the CODESYS Store has the oldest version V4.1.0.0 32 bit available. There is no way to find the CODESYS Linux runtime v3.5.14. So is there any work around for this? Or I cannot install the CODESYS Runtime on any of the Moxa IPCs based on the Moxa Industrial Linux 1 (Debian 9)?

Post by gurke258 on Codesys Safety EtherCAT with Beckhoff ^{CODESYS Forge talk (Post)}
Hello :) We are currently configuring a system with Codesys as SoftPLC on a Linux system and with Beckhoff terminals. I have already gained some experience with Codesys and also with TwinCat incl. TwinCAT Safety. What is new to me now is Codesys in conjunction with Beckhoff safety terminals. We are currently using an EL1918 & EL2904 here. I have been able to integrate both terminals into my project, but I don't know how to interconnect them so that they communicate. That's a bit easier with Twincat ^^ Can any of you help me? I would also prefer a Codesys EtherCAT Safety training or webinar if anyone knows of one. Unfortunately I can't find such an event on the internet.

Post by damian177 on Problem with downloading OPC UA tags by Data Source Manager ^{CODESYS Forge talk (Post)}
Hi, In Codesys V3.5 SP20, using Data Source Manager I am trying to connect to the OPC UA server and receive tags from it. The connection is ok, but the Codesys have a problem with downloading Tags group. The window (downloadingTags.jpg in attachement) never stop. After waiting for a while, I disconnect the connection and only the Server group remains downloaded, with OPC UA server diagnostic data (and this is read in Codesys). Of course, I tried connected via another OPC UA client : UaExpert , and everything works as it should, all tags are downloaded (Uaexpert.jpg screen). Has anyone on the forum encountered the OPC UA client configuration in Codesys? Is it possible to manually request the appropriate tags from the OPC server for reading in Codesys?

After creating a new project, i choose the device "Opus B3-B4-B6-3.5.19.50" that is already available in my version of codesys, but i think the problem is that my version of codesys or something else is not the same as the codesys runtime version running on my display. Can anyone tell me how i can see the codesys runtime version on my display? i tried looking in the settings (Daemon > CDS) on the display, but all i see is "N/A" for "Customer Number", "Customer Part Number" and "Customer Serial Number".

We are looking for the variable behavior from CODESYS has to change according to the message triggered by the CLIENT (we are using simulator Application like Redisant). We are able to see the log data as the status of triggering the SCS from Client received to the Log data of the codesys device(attached screen shot of it) and in simulator panel we had set the details to trigger the data from Redisant to Codesys. Current Status: The project builds and runs successfully, but I need guidance on how to connect this to an external IEC-104 simulator for testing and visualization by using demo mode.

I then create a new project on Codesys 3.5 and select the device "750-8216 PFC200 (WAGO)" (which I downloaded from the WAGO library). However when I have connected the ethernet cable from the WAGO device to my computer and on my codesys 3.5 i press "Scan Network" on codesys and it does not detect the device. How can I get it to detect the device? (I have put the ethernet cable from my WAGO to the computer, but it does not show the device).
