Open the CODESYS installer (you can open this as stand-alone tool, or from CODESYS Tools menu). Then go to Browse, search for Git and select install.

Hello, I tried installing ControlWin 3.5.20.40 and still have the same issue. I tried on 2 different PCs running Win10 Enterprise 2016 LTSB So I then installed the Gateway from 3.5.20.20 and it works. Is there an issue using ControlWin 3.5.20.40 with Gateway from 3.5.20.20? Thank you

Is it really the same CODESYS version with the same add-ons? Maybe open the CODESYS installer on your home laptop, and export the configuration. On your work PC open the CODESYS installer and import the configuration.

Does the OPC UA server have a generic username and password? It doesn't seem to be the same as the device username and password.

I haven't actually found an answer yet. It happens quite rarely, so testing and diagnostics are complicated. I've updated the software with every SP and add-on updates released, but it's probably a Kernel driver issue.

means not licensed demo mode.. use the Licenserver on the host and apply a license and add the Ip of the license server then it will be green.

@eschwellinger - We are experiencing the exact same issue. RunTime 3.5.19.70 and IDE V3.5 SP21. It's 100% reproducible. All you have to do is disconnect the network cable for about 10 minutes. OPC UA Crashes and requires a reboot to fix.

I can mention that i needed to update the firmware on the mitsubishi servo and then i got a step closer. The old firmware did not support FSOE but the new does.

Arrays with variable lengths are a bad idea. This makes your system unstable and can lead to crashes. Declare your array large enough to reserve enough memory

Hi Suyash! Stick to the IDE version used to create the project, and use Library Manager to fix version mismatches. Disable auto library updates and keep a record of working versions for stability. https://forge.codesys.com/forge/talk/Engineering/thread/0a4c242ab9/Italian Brainrot Clicker

In my case, I used a different version of gateway. ex)3.5.18.5 sysTray gateway start did not work, so I terminated it and made it work with 3.5.18.3 in "codesys installer" "Settings" and was able to connect to the PLC.
