The Considerations For PLC Ladder Programming Are As Follows | |
1. Ensure the correctness of ladder diagram symbols and logical correctness to avoid errors and logical faults in wiring. 2. Set the initialization state correctly for input and output points to prevent unknown states at startup. 3. Pay attention to the unit and accuracy when setting the value of timer and counter. 4. In writing ladder programs, pay attention to the uniqueness and accuracy of marker names to avoid renaming or misspelling. 5. Ensure that each program is complete and reliable. Step-by-step tests can be performed to find errors. 6. When using special function modules or library functions, read their description documents carefully to understand their operation and restrictions. 7. Insist on writing PLC programs according to specifications, such as: avoiding the use of jumpers, using equivalence links, checking loops, etc. 8. in the use of conditional jumps and other complex logic functions, should ensure that the code is simple and easy to read. 9. In the process of program design and implementation, the history of program modification should be recorded in time to facilitate future tracking or retrospective use. 10. Before PLC programming, adequate analysis of equipment and production process should be conducted before the programming program is developed to ensure programming efficiency and goal achievement. tft lcd module https://www.stoneitech.com/ | |
