Testing and Debugging

CODESYS provides various options for testing your application and detecting errors. You can start your application in simulation mode, even without connecting any hardware. Using breakpoints and stepping commands, you can examine specific parts of a program. By writing values to variables, you can influence the running program.

Commands are provided that reset your application in various different ways, from resetting only non-persistent variables to completely resetting the controller to factory settings.
