Part 11 How to use binary concept In PLC. hello Friend I this video we learn about of how to use logic gates in PLC programming.

1. How to use
Binary Logic Function in
PLC

2. Binary Concept
We have work in Two state:- ON / OFF
Same as Digital logic state:- 1 / 0
Example:- ON / OFF
Lamp:- 1 / 0
Motor:- 1 / 0
Horn :- 1 / 0
V / 0V
( + ) / ( - )
0.0 ~ 0.8V its means to consider low voltage
