hello im new to PLC programming and im trying to learn this skill and im really confused with data files and how they are used in addressing data files in PLC using ALLEN BRADELY software . how data goes 1 and how to figure out which bit manually set to 1 . CAN ANYONE HELP ME UNDERSTAND THAT CONCEPT BY GOING FROM FUNDAMENTALS OR RECOMMEND ME ANY CHANNEL TO LOOK INTO IT .
For the simplest form (zero or one), think of a data file (like B3) as a storage box. Inside that box are smaller compartments called “elements” (such as B3:0), and inside those are individual switches called “bits” (such as B3:0/1).
In your ladder logic program, if a sensor turns on, it can trigger an instruction that flips a specific bit from 0 to 1.
