What does AOI stand for in ControlLogix applications?

In ControlLogix applications, AOI stands for Add-On Instruction. This is a powerful feature that allows programmers to create reusable code blocks, which encapsulate specific functionality or processes. By defining an AOI, a programmer can simplify complex programs, enhance their readability, and make maintenance easier since the same code can be reused in multiple places within the project.

The use of Add-On Instructions also supports the concept of modular programming, where different parts of the application can be developed and tested independently, leading to more efficient development processes. Programmers can create instructions with parameters and local variables, giving them flexibility while maintaining organized and manageable code.

This concept greatly aids in program standardization and can improve collaboration among multiple programmers working on the same project.
