The SIMATIC Debugger is very useful for figuring out what your source code is actually doing. Before you can start, you require a valid Apax project including your source code, all compiled artifacts and a connected PLC. You can add or remove watchpoints and observe values in your terminal.

WARNING

The use of the SIMATIC Debugger CLI is not recommended. The output is not yet optimized for terminal use. We recommend using the built-in debugger in the IDE rather than the CLI.
