What term refers to the user text associated with the rungs and instructions of a controller project that explains their operation?

The term that refers to the user text associated with the rungs and instructions of a controller project, which explains their operation, is project documentation. This comprehensive information serves to clarify the functionality and purpose of each component within the project, allowing users to understand the structure, logic, and intended outcomes of the programming efforts. Proper project documentation plays a vital role in facilitating maintenance, collaboration, and future modifications, bringing significant value to any programmable controller system.

While a user manual, code comments, and an instruction guide all provide helpful information, they do not encompass the full scope of what project documentation entails. User manuals typically serve as broader guides for end users, code comments are brief notes intended for the programmers to clarify specific lines of code, and instruction guides may provide step-by-step instructions for operating or implementing a system. Project documentation, however, integrates all these elements into a cohesive whole that captures the entire project landscape, making it the most accurate term in this context.
