Users can manually add breakpoints in the breakpoint menu bar or ladder diagram. Taking ladder diagram breakpoints as an example, they can right-click on the location where they want to add breakpoints to pop up a right-click menu, and click the "Add breakpoint" button to complete the operation.

图1 Add a breakpoint

After adding a breakpoint, there will be a red rectangular element surrounding the corresponding component of the ladder diagram, indicating the existence of a breakpoint here.

图2 Break Point Generation

When the program runs to this position, it will automatically stay here and enter the PAUSE state.

图3 Break point operation

After adding a breakpoint, clicking "jump" will cause the program to run to the breakpoint and pause. Clicking "enable"/"disable" will switch the breakpoint between enabled and disabled states. Clicking "delete" will immediately delete the breakpoint.
