(4) LADDER LOGIC Part 2 | LADDER FREE LEARNING

Last entry,I'm said about Basic logic.
today i will say how to apply basic logic to more.


NAND OPERATION (NOT+AND)
Firstly,you should study Truth Table of NAND gate.

NAND Truth Table

(3) LADDER LOGIC | LADDER FREE LEARNING

LADDER LOGIC (BASIC LOGIC)

         LADDER Programming use the normal logic include AND logic,OR logic and NOT logic

Firstly, To coding ladder program you should learn the contact circuit.

AND Logic

Figure (1) :  AND Logic

AND Logic : According figure (1)  was meaning  A  and B  (A=1 and B=1 Output = 1 If A=1 or 0 and B=0 or 1 Output = 0)

LADDER STRUCTURE

(1) Ladder diagram | Ladder Basic

Ladder Diagram has evolved into a programming language that represents a program by a graphical diagram based on the circuit diagrams of relay logic hardware. Ladder logic is used to develop software for programmable logic controllers (PLCs).

Ladder Diagram has a simplify programming.
It's used graphic of electrical component like
relay,motor,coil,switch ... If you have knowledge about relay circuit you will understand ladder logic within 30 minute. I'm guarantee !

LADDER ...What is it ?

Hello,This's the first post.I won't say  What is PLC ?,How to PLC work?,How to switch on PLC (^_^) ...Etc.
This blog will be said about Ladder logic,Ladder programming,Application ...Etc.
