You can use this as short hand industrial automation dictionary.

In industrial automation study we used different short abbreviations.

I’m listing down those abbreviations in alphabetical order. Along with the full form, some of the abbreviations are linked to an article that will describe that terminology in detail like definitions, formulas, and usages.
