Post by matthewkim on Codesys Gateway not running ^{CODESYS Forge talk (Post)}
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.

Post by tk096 on SMC_ReadNCFile2 is always busy ^{CODESYS Forge talk (Post)}
Hi, do you process the sentences subsequently? If not, the function block fills the sentences (queue) and waits for the sentences to be processed, so that new sentences can be read and filled to the queue.

if this happens I go to --> Build --> Generate code then there exists a IDE Code and a PLC/API code and comparison before download is possible. Give it a try?

Post by imdatatas on MC_MoveAbsolute: C0138: No matching 'FB_Init' method found for instantiation of SMC_MoveAbsRelPerformerImpl [ERROR] ^{CODESYS Forge talk (Post)}
Dear @gseidel, Thank you for your reply. The exact version of Codesys and its compiler was 3.5.21.20. The compiler version was fixed and could not be changed in project settings. Since I couldn't continue due to this compilation error, I temporarily overcame this issue as follows. -- I completely uninstalled Codesys 3.5.21.20 and completely deleted the Codesys folder in the C:\ProgramData folder. -- I restarted my computer and installed Codesys 3.5.19.70. -- I updated the Codesys Installer and all its add-ons to the latest versions. -- The project that was giving me the compilation error I mentioned before is now open with Codesys 3.5.19.70, compiled it, and successfully downloaded it on the device. -- I haven't encountered the same problem anymore. I think this issue is related to SP21 and its compiler. Frankly, I'd expect a project created with an older version to compile without errors after opening it with the latest Codesys version and updating all libraries. Regards, imdatatas
