How do you document and maintain your HMI scripts and logic?

1 Why document your HMI scripts and logic?

Documenting your HMI scripts and logic is not only a beneficial practice for your own reference, but also for your colleagues, clients, and future developers who may need to understand, modify, or troubleshoot your code. Doing so can help save time and avoid errors by clarifying the purpose, functionality, and parameters of the code. It can also assist in communicating effectively with other stakeholders by explaining the logic, assumptions, and dependencies of the code. Moreover, documenting your HMI scripts and logic can ensure consistency and quality by following coding standards, conventions, and guidelines. Furthermore, it can facilitate testing and debugging by providing comments, notes, and instructions for the code.

2 How to document your HMI scripts and logic?

When it comes to documenting HMI scripts and logic, the type, complexity, and scope of your code will dictate the approach you take. However, some general principles should be followed regardless of the method you choose. Firstly, document as you code; don't wait until the end of the project. Secondly, use simple and consistent language that is free of jargon and ambiguity. Thirdly, provide examples to illustrate your logic and demonstrate functionality. Lastly, take advantage of the tools available in your HMI software or programming environment; comments, annotations, labels, variables, functions, modules, and libraries can all be used to organize and explain your code.

3 What to document in your HMI scripts and logic?

The content and format of your documentation may vary depending on the purpose of your code. However, there are some common elements that should be included, such as the name, description, and version of your code; the author, date, and revision history; the inputs, outputs, and parameters; the logic, algorithms, and calculations; and any errors, exceptions, or limitations. Additionally, you should indicate how your code relates to other parts of the project or system, as well as explain what steps or processes it follows and what formulas or equations it uses.

4 How to maintain your HMI scripts and logic?

It is just as important to maintain your HMI scripts and logic as it is to document them. Doing so can help you keep your code compatible with changes in your project, system, or environment. Additionally, it can improve code performance, efficiency, and reliability by fixing bugs, optimizing code, and adding features or functionality. Furthermore, you can enhance code readability, usability, and maintainability by refactoring code, removing unused or redundant code, and applying coding standards or best practices.

5 How to maintain your HMI scripts and logic?

It is important to maintain your HMI scripts and logic, regardless of the type, complexity, or scope of your code. To ensure that your code works as expected, meets the requirements, and does not cause any errors or issues, you should test it regularly and thoroughly. Additionally, use code review tools and practices to check that the code follows the documentation and complies with the coding standards or guidelines. It is also important to back up your code frequently and securely. Lastly, use documentation tools and processes to reflect any changes or modifications in your code, and to keep your documentation accurate and complete.
