The Debugger (sdb) is very useful for figuring out what your source code is actually doing. Before you can start, you will need to have a valid Apax project including your source code, all compiled artifacts and a connected PLC. You can add or remove watchpoints and see the values in your terminal.
WARNING
The use of the CLI is not recommended. The output is not yet optimized for terminal use, so we recommend using the built-in debugger in the IDE rather than the CLI.
