(1) Make sure all contacts are properly connected; otherwise, they might close automatically during the conversion process. (2) The vertical line segment should be directly connected to the contact. If not, the program may fail to respond or generate an error message. (3) When entering component labels, be careful not to confuse the number "0" with the letter "O." (4) When inputting timers and counter coils, remember the input parameters. There must be a space between the label and the parameter. (5) Always leave a space between the instruction and the operand for clarity and correct interpretation. (6) In ladder diagrams, the horizontal lines represent connections, which is different from traditional circuit diagrams where lines indicate actual wiring. (7) Pay attention to the layout of the diagram—each section should be clearly separated to avoid confusion. (8) Use consistent labeling throughout the project to maintain readability and reduce errors. (9) Double-check your work before finalizing the program to ensure that no steps were missed or misentered. (10) If you're unsure about any part of the design, refer to the user manual or consult with a more experienced engineer.
