PLC Ladder Program: OR and NOT Logic with Real-World Examples | Automation and PLC Series Part 5

[@jimcheriyan1801]

Great explanation and animation keep it up. Loved your videos on plc

[@srinidhij4588]

This is a lot more detailed explanation ,thank you

[@MM-fg3ep]

at 3:23: Instead of taking output of the alarm as an input of next rung; can't we do a parallel connection on o/p side of both "ALARM & BELT TO STOP" at first rung? so we can reduce one rung. any suggestions will be appreciated.

[@miss0368]

as a visual learner, I love your video as there are pretty animation helps me to understand

[@enggresgampang9524]

Thank you Is helpfull, simple and clearly

[@edwinnjeru6782]

Great explanation on PLC. I am learning something new

[@krishnavamshichikkaA]

way of explaining 🙏🙏🔥

[@johnlubango4158]

Balaa🔥🔥🔥🔥 now am understanding

[@hariprasad8531]

Thank you for briefing about plc programming

[@gvenagas]

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!

[@PhoenixMario]

Awesome Video!! I subscribed to your channel 👍

[@mnsjewel4508]

Great video. But im from no basic. What if the alarm not worked (or failed) but we need to stop the conveyer? We need alarm also but our target is to stop the conveyer first. Isn’t it?? Please ans

[@asdfkj123]

Yes, why dont we program Input 1 and 2 to directly effect the Conveyor motor instead of going through the alarm first, I assume this is just an example, but in real life would it be better to have both the alarm and the motor on the same Rung in the ladder logic? and would they be in parallel or series... Thank you, let me know what you think

[@durgeshdongre4422]

love you bro keep making such videos

[@germanhoernigappelius4418]

Muchas gracias. Son muy buenos, los uso para mis clases de Automatización.

Will you be making more plv ladder programming tutorials?

[@dongwang3569]

hiii your videos are great ,can u upload more, they are interesting and helpful

[@realstaticone8383]

Very nice idea to understand ☺️

Love ❤you sir kya explanation h

[@electricalmaintenanceteam7702]

Good job ❤️❤️❤️

[@syedhassanali9330]

Thank you very much sir, very informative video

[@HamzanMartinez]

Wouldn't it be better to stop the conveyor first then sound the alarm? (I1 OR I2) AND Stop_conveyor AND (alarm)

[@reubenmensah3224]

Perfect Explanation!!! Appreciated Pal Keep posting

[@adonesgella8239]

[@arkhan6319]

Thanks a lot for ur effort!

[@deepaa1994]

when the machine stops how will the contacts ne energised?

[@sithabisozwane3138]

Please help me with this ...a green light is on when any maches out of the 3 machines is operational, a buzzer is sounded and the green light is of if any of the 2 machines operate simultaneously, should an attempt be made to operate the third machine while the other 2 are still running the buzzer sound is switched off and the other 2 machines stop , the red light must now come ON untill the system is reset , which alow the running of a maximum of 2 machines at any time again.

[@kirankumargadwal4678]

Please do the complete course of PLC SCADA DCS and HMI

[@wilhelmimmanuel2628]

Great videos... Any way of getting into contact with you for ladder logic enquiries?

[@PracticalNinjas]

You can contact us [at] practicalninjas[dot]com

[@ngawanglekchung53]

wait so how the NO activate? like what triggers it to activate?

[@Time4yes]

On Rung 1, You use contacts as switches to pass the current , so you control them manually. Say, you press ON, that's how they will ACTIVATE since they are Normally open contacts. It also called latching, you don't have to press the switches for long, just touch and go. The second network, which controls the conveyor is always on when the power is ON, it only turns OFF when the alarm is. Remember, this is just a demonstration of how the ladder is constructed for certain functions.

[@abdmorioglu4868]

what is the program you use for simulation

[@firstepisoderecap3428]

Great video 😍

[@asitnagdeote5246]

Sir pls explain me why did we take 2 inputs?

[@Srk7028]

confusing part., Is OPEN means circuit is open and no supply ?NC and NO what is mean by it ?

[@juju4link]

Can you help draw plc circuit for when PET bottles, pass the sensor on air conveyor the alarm should sound when theres no bottle presence, when bottles are present, it should be quite. Then lastly when no production run, alarm should switch off automatically. This circuit it cant get any signal from any external equipment as modifications are not allowed, the circuitry should remain standard by company protocol.

[@sauravmazumdar5369]

Excellent...

[@JasbirSingh-iw9oz]

THANK YOU SO MUCH.

[@atulsinghtandan9232]

Nice explanation bro

[@praisethelord1026]

Please keep doing🙏🙏

[@gunaseelan5171]

How the NC contact becomes NO without any physical invertntion during alarm pls explain

Hi may I know is video Plc ladder progamming #3 uploaded?

[@PracticalNinjas]

No, not yet

[@Storyulagam02]

Please help to solve this problem A bottling process for 12 bottles operates as follows: a. Bottles are counted until all 12 are in position for filling (Filling Machine). b. When in position in the carton, the 12 bottles are filled simultaneously for 6.3 seconds. C. After filling, there is a pause of 3.8 seconds for foam to subside. d. The 12 caps are then put on and counted as they are installed (Capping Machine) e. A solenoid (5) then pushes the completed carton of 12 onto a conveyor. f. Conveyor (C) starts running. g. When the completed carton reaches the limit switch (L), that indicates that the carton is out of the "fill" position; the system is then reset for a new group of 12 bottles.

thank you so much!!

[@adamthefallnone1817]

I might have questions....k..... nevermind... I have a question. How do I delete parts of my ladder? I have an image/ladder of a newer machine on my "older" machine (same type of machine just built in different years), it is trying to read a pressure switch that never existed, I need it to read a float switch in the lube pump, not a pressure switch. I am an operator that got asked to fix something I have very basic knowledge of.. who can help?

[@plchero8370]

Nice guys

[@crazycanada2417]

buddy make video on Time delay switches please :)

[@sumanmondal5055]

good one

[@azharghulamhussein6930]

i 1 and i 2 should be in series not parallel. Because any of them will stop the motor on the second rung which is normally closed input will turn to an open one.

[@MiriamOyugi2022]

They should only be in series if he uses NC contactors but in this cases he uses NO and hence it's correct

Use a NOT gate! NC (normally closed) state.

How to implement not logic gate ?

[@rsmengg5970]

as already I1 OR I2 signal signal is not zero which means motors are not running and the alarm is raised to indiacate that then why should one need to stop the motor which is not running already....

[@sharivinraj5526]

ladder rung 2 alarm(NC) contact connect with the conveyor motor which means the conveyor motor will run until the alarm trigger. Once the alarm is triggered the conveyor will stop automatically. thank you

[@edwinbautista5027]

Thanks bro

Great

Calling the input instructions “NO Contacts” or “NC Contacts” is a poor approach to teaching Boolean logic in PLC/PAC platforms.
