8 .6 breakpoint debugging
1 ) Like other high-level language development tools, MULTIPROG supports setting
breakpoints for PLC programs for debugging programs. After setting a breakpoint, there are two
ways to debug the program: single step and trace.
Single step: The PLC executes the next instruction of the current instruction. If it is a
function or a function block call, it will execute the complete call process to get the result.
Tracking: The PLC executes the next instruction. If it encounters a user-defined function or
a function block call, it will open the corresponding code body. The tracking process executes
only one instruction at a time.
