Post by pernockham on Engineering IDE from linux? ^{CODESYS Forge talk (Post)}
Started playing with the idea of ditching windows for linux, one of the obstacles would be Codesys development. Alternatives: - linux with wine? - Run windows/codesys through virtual machine I guess a vm is the way to go? Anyone out there that could share their experience?

Hi, have the same problem. Tried various versions (3.5.17.0 3.5.18.5 3.5.19.0 3.5.20.1) When you compare two functions blocks inside one project, the compare function does work. Regards, Gerco

Did you create a certificate on that device already? Go to the menu View - Security Screen and check the certificates on the device. There should be one for your webclient FB.

Hello! One can create a symbol config entry in CODESYS by using create_symbol_config in a python script. Is there a way to create the xml symbol config file (!) from within a python script without going online? Thank you!

Our IPC has multiple seperate ethernet ports. Is it possible to have two ethercat masters on the IPC (on two different ehternet ports off course)? If so, is there documentation available on this, or are there watchouts? Thansk

Could you check the taskcycle time in the taskmonitor (online monitor) - do you really see this 1s on Ethercat Task? Need to check this on my hardware but will take some time...

Post by mondinmr on Frustration-Fueled Feedback on Project File Management and Git Integration ^{CODESYS Forge talk (Post)}
Good day, I’m writing this message out of frustration regarding the current way project files are saved as encrypted XML and single-file format in CODESYS. I find this approach to be quite tedious for several reasons: Limited Access to Structured Text: Not being able to access Structured Text (ST) externally makes it impossible to work with alternative editors like VSCode. Tools like VSCode are incredibly responsive and feature advanced systems such as GitHub Copilot, which would be a real game-changer when working with ST IEC. While CODESYS works well for small code snippets or debugging, when the codebase grows, switching to VSCode to boost productivity becomes essential, and copy-pasting between environments is a cumbersome workaround. Poor Integration with Git: This file format also makes it very difficult to integrate effectively with Git. I have tested the internal demo, but for advanced merges, it is unusable. Without properly formatted plain text, it’s impossible to leverage the vast ecosystem of external tools around Git that allow smooth merges in heterogeneous teams. File Corruption on Network Drives: I often work from multiple locations with shared network drives. When the development environment saves a file and something goes wrong midway (which can occasionally happen when using VPNs and network drives), the entire project becomes irrecoverable. There’s no way to cancel the save process, and the development environment freezes. This has happened to me at least four times over the past two weeks, and one of those incidents cost me an entire day of work. All of this is particularly disappointing because I truly believe that the libraries, runtime, and overall work done by CODESYS are exceptional. I find it fantastic that there is a platform allowing development of PLCs and control systems using OOP, which is a huge advantage in modern control engineering. I apologize for the rant, but this issue has been extremely frustrating. Best regards.

Hi i have a project where i am communicating with many modbus devices using TCP to serial. This is all working extremely well except when i turn one of the remote devices off. If i leave the auto reconnect on it still doesn't talk to the rmianing devices and if i turn Auto reconnect off it locks up. Any help would be appreciated. Paul.

Post by tk096 on gear over gear (2 masters,1 slave) - how to do it? ^{CODESYS Forge talk (Post)}
Hi, you could calculate the position/dynamics of the slave axis yourself and use one of the function blocks SMC_FollowPosition/SMC_FollowSetValues to move the slave axis. https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/POUs/Movement/Direct/SMC_FollowPosition.html https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/POUs/Movement/Direct/SMC_FollowSetValues.html
