In this episode, we will understand what is PLC ladder programming
PLC is a logic controller which has inputs and outputs to control a particular process. The relation between these inputs and outputs is established via a control logic. This control logic can be written using different programming languages. One of the most common and easier to understand language is the ladder programming. Check the video to know why the language is called ladder programming.
This video further discusses what are NO (Normally Open) and NC (Normally Closed) contacts and how they can be used in control logic to achieve a specific task. These programming blocks are explained using animations and example. The logic for AND gate is developed using these contacts. The further videos in this series will also cover more examples on developing logics using NO and NC contacts.

One suggestion to avoid confusion ,NO and NC terms are supposed to be used to indicate initial or normal condition ,if actuated/pressed NO contact become closed and same should not be called NC , similarly NC contact opens not to be called NO.

Agreed!! Great video but that part confused me. Thanks for pointing it out

In electrical switches and switchgear NO or NC means that state of switching element position before applying electrical or mechanical energy on it.

@AlexofSmeg 2 жыл бұрын

I also thought this was stupid. NO doesn't change to NC when pressed, it simply changes to C.

No not the same as motor control its values or true or false. Its opposite to what you would think

@markjustdiditc 2 жыл бұрын

@@nephilimshammer9567 this guy is right..... programmable logic controllers only think in true and false, and they are advanced and simple at the same time.... if you plug NC or NO contacts from a normal relay into a PLC, it doesn't recognize it as "normally open or normally closed" unless you tell it to, via the True and False logic.

@blairwilkie6374 3 жыл бұрын

Very nice video; HOWEVER, a rather IMPORTANT point of clarification needs to be made. A device (such as a pushbutton or PB) that is Normally Open (NO) DOES NOT become Normally Closed (NC) when it is pushed. The NORMAL state of a device is its SHELF (i.e. out of circuit) state. Hence, the contacts of an NCPB will indeed CLOSE when the button is pushed; however, its NORMAL state (i.e. when NOT pushed) has not changed.

@PracticalNinjas 3 жыл бұрын

We completely agree with the points you have presented. A physical device manufactured as a NO type can never become an NC device. A lot of viewers have been confused with this point even though we never intended it. To bring more clarity on this concept, we are preparing next video on the same topic and differentiating between actual physical input (push button) and logical input (ladder blocks)

Very well defined. Most Electricians (Not dissing Electrical guys) do not know digital logic. Let alone boolean algebra. But this is the basis upon which the PLC processor works. It is , a microprocessor ( maybe soon a FPGA) that is handling the inputs, outputs and control logic.

QUESTION In a corridor there are four switches and three bulbs. when a man enters from one side of the corridor and presses switch 1,bulb 1 gets on when the man presses switch 2,bulb 2 gets on and bulb 1 gets off. When the man presses switch 3,bulb 3 gets on and bulb 2 gets off. When the man presses switch 4,bulb 3 gets off. The same thing can happen if at any instance a man enters from any side the 3 bulbs. Write a PLC ladder logic.

@gvenagas 2 ай бұрын

Good evening! Forgive me if I am wrong but I have found some things that hinder my understanding of the terms NO/NC physical contacts and MAKE/BRAKE XIO/XIC internal PLC logical contacts. First, i tend to believe that a circuit is activated when there is some action (pressing a physical button or contact by the user or when the physical relay coil is energised and therefore magnetizes the contacts. Second, i tend to consider the user physical switches and the logical internal contacts of the PLC program as contacts of one state, because that way the brain thinks more simply, while they are two states by definition (double throw). So even in the case of non-activation by the user or PLC program there may be an active circuit/load. With the terms NO/NC I personally like to refer to the user physical buttons or contacts while with the terms XIC/XIO, MAKE/BREAK the logical contacts inside the PLC program that are activated by the user. To what extent am I correct in my words? Thanks!
