Post by sturmghost on Find visualization elements that require a lot of computing time ^{CODESYS Forge talk (Post)}
I found out that the Codesys simulation mode is not good to measure performance. As soon as I upload the code onto the hardware PLC I can see that my visu-task needs around 60 ms to complete. I'm wondering if there is a possibility to find out which visualization/visualization element takes a lot of computing time? Then I would look for ways to decrease the long computing time.

Post by mozed on Signature verification faited fro the following package ^{CODESYS Forge talk (Post)}
Good morning, I'm trying to open a project but codesys tells me that there are certain packages that I don't have and that I need to download them. Once the installation of the packages begins, it shows me a error that the signature of certain packages does not correspond to that coming from the accepted installation context. Do you have a solution to my problem please, it is very urgent in my work. Sincerely

Post by programmierer on Implementing UDP Communication ^{CODESYS Forge talk (Post)}
Hello everyone, I hope you can help me with my problem. I am new to programming and am currently working with a WAGO controller in our lab, which controls a heat pump. My goal is to send the electrical power of the heat pump (Pel_WP) via a UDP connection to a specific IP address. I am using Codesys version 2.3 and following the guide I found here: https://forge.codesys.com/forum/de/396/genmed-Konfiguration%20der%20UDP%20Kommunikation%20Cosesys%20S7.pdf. I have adapted the guide to suit my needs. The data sending works since I can force the reception value Pel_WP and the data is sent accordingly. However, I am having trouble with the receiving part. The reception value is not being correctly received, and the diSocket variable shows -1. The connection between the heat pump and the WAGO controller seems to be set up correctly, as the heat pump is listed under the communication parameters with the correct IP address. I have also attached images to provide a better view of the setup. I would greatly appreciate any support or suggestions for a solution. Thank you in advance!

Hello, I’m looking for the ecoPlus21 development environment used with early IFM controllers (e.g., CR0020_Q firmware). We have an old project created in ecoPlus21 that cannot be opened in CoDeSys 2.3, and IFM no longer provides this software. If anyone still has the ecoPlus21 installer or knows where it can be downloaded, please let me know. It’s needed only for recovery and migration of an existing project. Thanks in advance,

Post by fredruel on ModbusServer became unreachable if reach maximum of 16 byClientConnections ^{CODESYS Forge talk (Post)}
Hello Fraziersedge, the solution of Codesys might be to update your codesys to the lastest version but it was not possible for us. In our Codesys V3.5 SP9 patch 8 I was able to fix this bug. I change my ModbusTCP slave component version or one of the sub component version (ex: SysSocket). Look at the picture in attachement that's the receipe that have work for us. When I got the bug my version of ModbusTCP slave was 3.5.5.0 with SysSocket at 3.5.6.0 and I change to ModbusTCP slave 3.5.14.0 with same version 3.5.14.0 of SysSocket event if I still use codesys V3.5 SP9 patch 8.

Post by gunstr on CODESYS control on RPi starts, shortly runs, then exits ^{CODESYS Forge talk (Post)}
The problem has been resolved. Two findings are described below for future reference. The new RPi hw delivered during August 2025 has a MAC address from a new vendor series that is not supported by old runtimes. 4.17.0.0 or above is required. 4.17.0.0 does not pick up the correct architecture during installation and aarch64 has to be manually configured either in the GUI under operations or in /etc/codesyscontrol/CODESYSControl_User.cfg under the [CmpRasPi] section.

Post by trusty-squire on parker servo and position ^{CODESYS Forge talk (Post)}
@gepert, When you say "I do not turn off power", are you saying you don't power off the drive, or you don't turn of the MC_POWER function block? I read your statement as you don't kill actual electrical power. MC_POWER should stay enabled. @Gustavo, not related to problem at all, but when you say 1.6 Nm is only enough torque to unscrew a loose bottle cap, I think that's a bit low. A quick mental math I use is 1 Nm is almost the same force as 1kG applied to a 10cm wrench. So 1.6kG applied to a 10cm wrench is still not a huge force, but more than enough to be felt if trying to turn the shaft by hand.

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 totorovic on CSVReaderInit returns error : INVALID_HANDLE ^{CODESYS Forge talk (Post)}
We changed the path where the CSV file is. From intern memory of the IPC to a USB key. We still have this error 'INVALID_HANDLE'. We must restart the Codesys runtime to clear it. That is a big problem for us because machine is in production. @eschwellinger What do you mean by "this is a security issue not to read/write in the plc allowed path"

Indeed, I'm also seeking a solution for this issue. The main challenge we face is the requirement to use EV (Extended Validation) Certificates. Due to security considerations, it's not possible—nor is it ever recommended in such cases—to export the certificate with its private key.

In your soft plc folder, there is a file called targetvisuextern.cfg. Open this with a text editor to change the settings. Remove the semi-colons in front of the lines to enable your custom window settings. WindowType=0 means you will get a moveable window. Save the file and restart the soft PLC to enable these settings.

Post by dhumphries on Using Codesys example problems ^{CODESYS Forge talk (Post)}
You have to install any libraries needed by the sample program. Click the button with ... next to one of the errors (see attached image,) then choose download missing libraries. Codesys should automatically locate and install the missing libraries, it's not flawless though, I've had some issues getting libraries to install. The best advice I can give if it doesn't work is re-install Codesys.
