Lacking such a driver you can still develop your own when you manage to sweet talk your Keyence sales representative to find those C header files for the DLL internally. For a few device groups there even exist (customer made) LabVIEW libraries that interface to the according DLL that Keyence can sometimes share with other interested users. It seems each device group is developed at a different place with a separate software development team for each of them too.įor most of their devices they do have a minimalistic C header file for that interface DLL they can send out to customers but you need to find someone inside Keyence who is willing to go through the trouble of optaining that information internally and sending it to you. Amazingly the DLL used is for each of the Keyence class its own specific version too, I can't really imagine what software development strategy they have.
