For various on-site hardware configurations and software debugging, usually experienced engineers should spend some time to make a simple plan for their on-site work. Usually, they should take the following steps
System Planning
First of all, it is necessary to have an in-depth understanding of the functions required by the system and investigate possible control methods. At the same time, discuss the best operating procedures with users or design institutes, and formulate plans based on the conclusions drawn. System planning determines the adopted system architecture, required points and module types.
/Module Selection and Address Setting
When the /module is selected, the system automatically sets the /address according to the planned /point usage situation, or the user defines the /module address. .
Writing Ladder Diagram Programs and System Wiring
After determining the actual /address, start writing ladder diagram programs based on the functions required by the system. At the same time, the address of / has been set properly, so the system wiring can also be started.
Simulation and modification of ladder diagram program
After the ladder diagram program is written and the program is written, the online connection to the system can be made first to perform online simulation operations. If the program execution function is incorrect, you must debug and modify the ladder diagram program.
System commissioning and actual operation
Under the online program simulation operation, if the ladder diagram program execution function is correct and the system wiring is completed, the system can be put into actual operation and the project plan is completed. .
Program annotation and archiving
In order to ensure the convenience of future maintenance, it is necessary to annotate the ladder diagram program that has been tested correctly and can be used for actual operation, and organize and archive it to shorten the time for future maintenance and review of the program. This is a good habit for professional engineers. Whether you maintain it yourself or hand it over to users in the future, this will bring great convenience and is a reflection of your professional standards.
In the above work, complex system planning may take several days or even longer, but a simple system planning in the hands of a programming engineer with good professional habits may only take a few hours.
I want to emphasize a problem here, which is very simple but occurs in almost every project, and that is correct wiring. This is often an issue that is often overlooked by inexperienced engineers. In fact, most of the problems and workload in on-site debugging are related to wiring. An experienced engineer should first check the wiring at the site. Usually, if the on-site wiring is completed by users or other construction personnel, you can have a rough judgment on the quality of the wiring by looking at the wiring diagram and the appearance of the wiring. Then give all wiring a complete and careful inspection. Burning out occurs frequently due to incorrect wiring on site. Be sure to check carefully before proceeding with actual debugging. Even if wiring is not your job, checking the wiring is your obligation and responsibility, and it can save you a lot of time later.
