Post by mondinmr on Frustration-Fueled Feedback on Project File Management and Git Integration ^{CODESYS Forge talk (Post)}
In reality, other vendors are already moving towards integration with VS Code. B&R, for example, is likely the only one that could truly challenge Codesys in the market: they’ve overhauled their once-archaic environment (previously lacking ST OOP) and are now catching up significantly with Automation Studio Code, offering modern programming capabilities and native support for tools like Git and GitHub Copilot. The other big names in the market, frankly, are still light years behind. For smaller projects, typically handled by “wire strippers” (with all due respect!), a classic environment might be just fine. But once you’re dealing with thousands or even millions of lines of code—possibly organized in an OOP paradigm, spanning large teams, integrating third-party libraries, requiring version control, and performing comprehensive tests—a lightweight, responsive editor supercharged with AI-based features becomes essential. The real strength of something like VS Code lies in its vast ecosystem of extensions and integrations: from advanced Git support to automated build/test pipelines, and even AI-assisted autocompletion that already makes software development much more agile and productive. I understand that a PLC project involves more than just ST code (task setup, fieldbus configuration, libraries, etc.). However, there’s no technical reason not to at least provide ST files in a pure text format, making version control and collaboration far easier. B&R has clearly adopted this approach; I hope Codesys will accelerate its own efforts to offer a native, text-based integration and modern development tooling. Once you go beyond a certain level of complexity—dozens of configurations, OOP hierarchies, and distributed teams—you really do need “engineer-level” software tools, not just solutions targeting “wire strippers.” For large-scale automation projects, a more open and flexible approach is the only way to avoid chronic frustration. Let me emphasize that I truly love Codesys and consider the work done so far to be brilliant—I’d be sorry to see it overshadowed by others moving faster in this direction.

Post by jrsantab on Remote connection to ifm PLC & HMI ^{CODESYS Forge talk (Post)}
We have finally solved the problem. The version of the Gateway in the computer that worked (3.5.11.0) and the one that didn't (3.5.17.30) was different. We have three different Codesys 3.5 versions installed because we work with different controllers. I believe that, depending on the sequence you follow to install the versions you get a different Gateway version. To solve the problem you first have to disable the "obsolete" services. Open services, serach for (in our case) CODESYS Gateway V3 Version 3.5.11.0 CODESYS ServiceControl Version 3.5.11.0 I stopped the services and changed to Manual Start. Then you have to create the new services. In our case, from a Command Prompt session (cmd): SC CREATE "Codesys GatewayService Rigual" binpath="C:\Program Files\CODESYS 3.5.17.30\GatewayPLC\GatewayService.exe" and then SC CREATE "CODESYS ServiceControl Version 3.5.17.30" binpath="C:\Program Files\CODESYS 3.5.17.30\GatewayPLC\CODESYSControlService.exe" remember also to set them as Automatic Start!

Hi, Has anyone managed to use the last four buttons in a POU toolbar in LD2? You can close and open by clicking from one small rectangle to another (same for deleting a closure //). Linking K to D causes a series connection with all the branches // above. Amazing! I don't really see the advantages of this supposedly modern and efficient language over the old LD/FBD. Can anyone explain?

Post by kleeswi on SysFileOpen does not work after update to V3.5 SP19 Patch 5 ^{CODESYS Forge talk (Post)}
I use the function SysFile.SysFileOpen(sFileNamePara, SysFile.ACCESS_MODE.AM_WRITE, pErrorFileOpen); to open and write a file. Since the update from Codesys V3.5 SP17 to V3.5 SP19 Patch 5 it does not work anymore. I first had SysFile.SysFileOpen(sFileNamePara, SysFile.ACCESS_MODE.AM_APPEND_PLUS, pErrorFileOpen); in both versions. hFile_Test is a pointer to byte. It gives an exceptional error when dereferencing the hFile_Test pointer. Edit: I use Codesys on a Raspberry pi

Post by astutoski on No Motion with SM3_RaspiStepper (GPIO 23/24 Show No Pulses) ^{CODESYS Forge talk (Post)}
Hi everyone, I’m completely new to CODESYS and have been teaching myself. And i Want to control an Axis using SM3RaspiStepper. Following the example on the RaspiStepper home page, I set up an axis through a POU and tied the SMC_StartupDrive (Visu) template to my axis instance (sud). Unfortunately, the motor never moves and I don’t see any pulses on the PULSE pin (GPIO 23). Hardware -Raspberry Pi 4 B -Nema 17 stepper motor -A4988 stepper driver (EN pin permanently tied to GND) Software / Runtime -CODESYS 3.5 SP21 Patch 1 – Raspberry Pi runtime (demo) -SoftMotion in demo mode -Package: SM3_RaspiStepper 0.0.0.6 Axis parameters: Pulse pin GPIO 23 Direction pin GPIO 24 Enable pin 0 (unused) Disable pin 0 (unused) Whether I start the axis from the visualization template or through Online Config Mode, the motor never spins. In Online Config Mode I press Power → the state changes from Standstill to Discrete_Motion, but the motor shaft is still locked and no step pulses appear on GPIO 23 (checked with a scope). I can provide screenshots of the Visualization, PLC logs, or wiring pictures if that helps. Any ideas on what I might be missing? Happy to provide screenshots, project files, or scope captures if that helps. Thanks in advance!

Post by berto on Opening PDF in Web Browser in Target Visu HMI ^{CODESYS Forge talk (Post)}
Hi everybody, I've been facing problems with the PDF visualization in Web Browser. I am trying to open a pdf file called 'sample.pdf' which I manually saved inside PlcLogic/visu folder. I am setting the web browser URL as: 'http://127.0.0.1:8080/sample.pdf' but I get 'refused connection'. I got a similar error trying to open https sites and I discovered that I can only open http websites. Opening 'http://de.wikipedia.org' everything works fine. I also tried to check using code whether the sample.pdf is present in the directory. Unfortunately, when I try to read directories of 'PlcLogic' I get file FILE_OPERATION_DENIED (I am using File.DirList). I would like to be able to open PDF files in web browser. Possibly to move new PDF files in the folder as my customer wants to display different pdf manuals on the hmi. Here you find some screenshots and my .project. I am using Codesys 3.5.19.70. Best regards, Berto

Hi, I tried some different libraries (CmpApp etc.) to find some global variables that I could read out as a variable in the codesys environment. Do any one of you know which libraries are best suited for this, and how I can read it out? My goal is to send messages, warnings etc. to the system that communicates to the PLC. Currently if something goes wrong I need to see the logfiles, or go online with the controller. I think I could save a lot of time if I could read the errors from our user interface that is connected to the PLC by TCP/IP.

Post by janber0206 on Adding PLC to the List view resolves in Unknown Error ^{CODESYS Forge talk (Post)}
Hello, I try to add one of my PLC from the Gateways to the List view. The Gateway is shown me as online, also i have other remote tools to verify the Internet connection is working. I do the Network Scan and the Gateway shows up, i select it and click on "Add to Server". Then I type in Username and password and click on confirm. There it shows me the "Unkown Error", see screenshot. If I use the wrong credentials it gives me the error message for this. Other Devices work fine it's just this one. Greetings Jannis

Post by rshabsh on Using Latch Variable in Alarm as input from text list ^{CODESYS Forge talk (Post)}
I am currently utilizing Alarm Manager’s Latch Variable 1 to display additional information related to alarms. However, instead of mapping this latch variable to a fixed PLC variable, I would like to dynamically update its text content based on the selected language in the system. To achieve this, I am considering using a text list that corresponds to different languages rather than directly linking Latch Variable 1 to a PLC variable. This approach would allow the displayed alarm information to be automatically translated according to the active language setting. Could you please confirm if this method is feasible within the Alarm Manager configuration? Additionally, if there are specific steps or best practices to follow when implementing this functionality, I would appreciate any guidance you can provide. Looking forward to your insights.

Post by anderson on function block output ^{CODESYS Forge talk (Post)}
I'm trying to make a CNC machine, but I'm having problems because the drive I'm using only has the option of communicating through digital inputs. In this case, I should use the CLP's digital outputs to communicate with it, correct? However, in the function blocks it seems that they are already pre-programmed and I didn't find the pulse output options, for example, so that I could associate a digital output from the PLC to connect this to the drive's pulse input. My question is: is it possible to associate the pulse output of the function block with a digital output of the PLC? and how to do this?
