Omron PLC E-Learning Lesson- Introduction to PLC



hi guys welcome to learn be using and a session on in today's session we are going to learn about omran PLC now omran we are using a model CP i– CP 1 okay and this is this video is brought to you by NFI learning made easy and in this series of videos we are going to see how to wire the PLC however the Omran PLC so we have appeals in right over here in the drainer that's the plc trainer for the home run that's your on PLC and we have some IO box here for the input and for the output so we are going to wire up this wheel's you to show you how to wire a real PLC open on VLC okay so to begin with I'm starting with the basic terminals basic connections should we do have in the own run PLC right so in the open because you will see these are the inputs at the top you can see common 1 2 3 up to 11 it has this has these number of inputs okay and that's the area where we put the battery batteries required suppose you have a large memory you have some information in the PLC some information which you are storing from long enough okay and and if you're badly got a weak you know batteries used to store that information so we need to replace that battery often so that your information is stored inside that okay that is a space where you put the battery that is used to store your last memory information in the PLC that's the normal programming cable we use a USB cable which is oftenly used in the printer cable similar to that as well it's used became and these are the plc processes status okay so I can see that this is right now power on wheels is running PLC run light is also on so P gen C has been given the power and it's running so these are the status symbol say status indications here and these are the plc outputs PUC output wires are you know being wired up here and then you have PLC i/o status I have status means input output status this orange light indicates that this in this on right now this indicates that this is the outputs of this output is on right now in the pinned SBHC okay so there are different status you have input battery programming cable processes status output and be in CIO status okay so now we are going to program the plc for that we'll show you how to wire that okay so the solution is more of the wiring part so let's see how to wire the plc so I'm showing you in this web compartment alright so now we have pins here now in this PLC we have first terminal as common okay this is common to all these inputs these are the inputs input 1 input 0 1 and up 2 input 7 okay so how to wire this input now let's say the first task is I want to detect the presence of the switch if I press the switch this should turn on my first input in the PLC okay so let's see that how we can do that so I'm going to use a couple of wires so the first thing which you need to understand is the common okay now this is the common of my input I'm going to connect here 0 volt this black wire I am using for 0 volt so I have a power supply at the back that's my power supply here which has 24 and 0 volt terminals so the 0 volt is connected to the common okay now the general idea is if I connect 24 here this input will be detected because we have to maintain a potential difference between your common and your input that should be 24 volts potential difference between your common and your input if you wanna see a diagrammatic explanation this is some replicas of the soman PLC I have a common here so to the common I am connecting 0 would okay now to whatever input I give 24 volt from the outside this input will be on okay so that's what I'm doing so here in this input force I am going to directly connect 24 volt just to show you the status so this 24 volt here without using any switches I just connect it here so you will notice there is a small ad D which is on here if you can see the LED there's an LED here or if I just make it closer then you can see this LED is on because 24 is connected to input 0 and this is 0 so we are maintaining a potential difference so if I remove it this LED is off if I can enter the second one zero one second LEDs on so on third fourth this next one so whatever input you can a 24 volt it has you know the potential difference fundamental if you maintain a puncheon difference between your common and your input which should be 24 because this is a DC input PLC this is little breezy 24 volts input will be detected all right now if you do the vice-versa now that's 24 volt I'm going to connect this 24 volt to the common okay now that's the 0 volt wire if I connect this wire here again you have an LED which is on okay let's have a look at here gets now this is 24 and that's 0 so we have seen that you know either you can use a 0 volt or a 24 volt to the common the other one should be connected to the input this is 24 volt here if you can exceed oh here this input will be activated like here here is good okay so both ways will be working so generally what I'm going to do a here is I'm going to connect 24 to the common and 0 volt I am giving to my inputs so if you see this i/o box we have this force this is a selector switch NC switch to i know switch and this is an emergency okay so 0 volt i am connecting to my common of all the inputs now this terminal is the common of all the inputs what I mean button in every inputs we have two terminals okay one is the outward one is the input so we have shorted each input to one terminal okay now these will be the outputs so I'm going to connect the output of this one or any of these inputs to my first input of PLC to get my switch detected and the PLC that's what that's what we usually do okay so now now my zero volt is connected to the common of my i/o box I'm going to connect the first input as this one okay this goes to my zero zero here forced input okay now if I turn on this input if I run the selector switch you will find the indication here this is on okay you wanna see this is on because electro switch is on if I turn off my selector switch this is off now okay now let's have one more switch connected to my PLC now this time let's connect an NC so this NC from here go to my zero one my second input so you can see that this is already on because this is NC so that's already passing the signal so this is connect you to my zero one so similarly I can connect my other inputs to my next input of my PLC this goes to zero two and the next one goes to 0-3 okay we are just understanding how to wire so we have four inputs connected 0 0 0 1 0 2 and 0 3 that is my first one is the selector switch second is an NC another two are a no so when I can when I press my end of switches from here you can see the inputs are getting on so this is on here this is on here okay so that's how you can wire up the input connecting the input IO switches to the inputs of VLC ok so to understand that in more planification way let me use some diagram ok so what we have done is the first one we have connected a selector switch so we are we are using 3 position out of which we are just using the one position because we don't have the other position in my trainer so I'm going to use a power supply so what we have done is we have connected to 24 volt in our trainer to the common this is the common and that's my first input so let me just put it here which is connected to 0 volt and this is going to input 0 my second one is NC switch so I'm going to take a switch from here this is my NC switch put it like this this goes to my input 0 1 and this is connected to 0 volt because I told you 0 is common to all the buttons then we have 2 n Oh switches okay let me put it like this like this ain't no switch and this goes to zero as well this type of wiring is generally you'll find in all the PLC 24 and 0 fundamentals as always you can appeal to you okay is that these are two NO switches this is an TN is a selector switch so that's what we have done in our trainer if you have any community you can post me a question on that this is an input wiring we can do we can connect this emergency as well okay let's do that I'm using us using this wire to connect an emergency 2:04 okay zero four I still have three inputs left so I can connect if I have a sensor or a limit switch I in connect those inputs in here okay in the simple VR three inputs left and five of them has been used so that was about wiring the input now let's talk about wiring the output which is again a very simple concept okay so let me just put it aside all right now you have an output you have first is the common and then you have an output then you have another common another output now the common has been highlighted with the black terminal this red one is the output then another common another output two outputs then one more common and then you have two more outputs one more common and one more outputs now this concept of common is more like the concept of contact of relay normally open contact this is actually the normally open contact of a relay okay so what happens when this output is on from the PLC right now you can see that we have a dummy program in which your output is blinking okay in the PLC now whatever you give to the common C 0 this will come out from the out 0 when the output is on from inside the PLC that is what the fundamental is so if I give 0 volts here and if the output is on here this will give me a 0 good okay if I give 24 volts here this will give me 24 volts if I give 10 volts or 5 volts whatever I guess that's what gave me the output but you have to make sure the embedding of your outputs of the PLC that should match whether your ampere rating of your load okay so what I'm going to do is I'm going to connect 24 volts to the common okay that goes to back of my PLC that power supply now the 24 volts I'm going to connect to one of my indicator okay which is over here now in IO section we have five indicators in which this is the common of all this indicator that is a zero volt and this is a 24 volt input that's a DC indicator okay so I'm going to connect output of my PLC from here to one of the indicator over here right over here okay so this is getting 24 volts because my output is on and off on and off I have a dummy program so as you can see here this is blinking out zero is blinking force output all right now what I have to do is after the next seed over here see the blinking happening okay so let me take another wire to connect zero volt into the common of our i/o box that goes here so the moment I can exceed a volt I have my potential difference totally working so this is getting 24 volt here this is on because it is getting 24 volt here from the PLC from this C 0 because C 0 is getting 24 volts and this Jennifer comes out of 0 0 when the output is on and the output is off 24 doesn't come here so it has 24 volt potential difference if I connect this to here this will blink or to here this will also think similarly here as well and here as well so let it be here so my first output 0 0 is connected to my first indicator here I'm just showing the wiring I'm doing the similar for the second one so what we'll do is we have five indicators in our IR box so we are going to connect five outputs here so to have five outputs first I'll do what I'll do is I'll just shot my comment this is my comment this should be given 24 as well so I'm going to short that my comment zero like this because I need 24 at all the comments so that is a simplest and easy way to do that now I'm going to short another common which is C 2 to the C 1 because it also needs money for volts ok so we have 1 2 3 4 I need two short C 3 years we'll wait ok we are done with that so we have 4 outputs here to this one and to this one those are going these will be going to my indicator so 0 1 will go to my second indicator this red one ok this is not on because this is not even on in the PLC itself but will be making some logics to turn on these outputs and the screen indicator this will go to 0 2 here 0 2 and the next one is 0 3 this will go to my second last of these and then we have another 1:04 that is going here alright I hope that makes sense a little complex looks like you little messed up but yeah it's an educational trainer so we gonna do anything about it so what we have done in not a nutshell this 24 volt let me have it here as well all those is the same supply but just to clean the wiring this is connected to C 0 to C 1 and C 2 okay then we took some indicators I'm gonna get indicator from here I need more of these let me just have copy/paste 5 first one is connected here oh hold on let me just extend it yeah first one is here second one is here third one is here what was here and fifth was here okay these were shorted and we're given 0 volts from one end to the common okay so this was the wiring of my PLC which is very easy just the concepts of 24 volt and 0 here we have to maintain a potential difference but here we will get the voltage which we apply to the common from the output when the output is on from inside the PLC ok so this was a basics of firing of PLC ok so let's move ahead next is to understand the addressing now this over on PLC CP 1 e we have inputs input elements being addressed by 0.0 up to 0.7 so the first input will be addressed as 0.0 okay then you have an output output is addressed as 100.000 dot 0 7 these are the addresses of outputs so we'll be doing that in the PLC programming then input memory these are the internal release internal bits of a PLC addressed by W 0.02 W 5 and 2.0 these are bit-bit addressing okay these are also the beta dressing then you have timers inbuilt timers ranging from T 0 to t 4095 similar as counters but in timers and counters we have a condition that we cannot take seem addressing for timers and counters for example if you are using t 0 0 already in your logic you cannot use counter c 0 0 0 you have to use c 0 0 1 or 2 or 3 but not the same that's the condition in the own on VLC not in other PLC's but we have a normal plc that resistor i used to store the information so we have 32,000 768 data resistor ranging from 0 holding resistors are those which are latched which will be on even the power is off so when you regain the power these will be large will maintain its state these are the holding resistors so we'll be doing these resistor using that in or a couple of logics all right the next topic is speeds is static input/output check we have to check the inputs what we have connected we have already checked the inputs by pressing the switches but we can also see that in in our plc programming software as well ok so let's do that in our PLC so the PLC programming software for Imran scx programmer we are going to use this programming programming software for our pizzas so first we'll go to the new when you are new when you open the software press on new ok then it will ask you the device time so this is generally mentioned in your PLC – cp1 e so i'm going to select that then go to settings because in this one you have also have different types of CPU so – n for in select yours if you are using any other press ok the network type is how you are connecting your PLC so these are the different wires so we are using usb simple USB so just select your USB ok that is a wire which you can see here that is a USB bar connected to my computer ok then press ok then you will be given a screen now in the screen what you have to do is for input/output checking first go to online okay go to online press yes and if your communication is perfect you'll be given online then go to tools switch box utility okay take this box here now this is the monitoring if I put here 0.0 this is the status of my input okay then you have 0.1 0.2 oops not 9 so your dot 3 your dot 4 5 6 7 7 so now you can see that with respect to this programming window okay now my first input is a selector switch which is right now off if I turn it on you can see the status here this is on status is on the PLC as well but in the software we generally see because some time it's very difficult to locate the PLC if it is in the panel on the machine so you can open your software and see the status here zero zero zone because the selector switch is on this is called static input checking now second is the NC this is an NC that's why this 0.01 is on if I press this one this is off in the software this is the NO so you can have I press this one 0.02 is on and this is the 0.03 if I press this one this is on the 4 is my emergency if I press this one 0.04 is off otherwise oh this is on ok now the status of output on the here you can write 100.000 software output so if this is blinking when this is on you see the status on when this is off you see the status here in is off so that's giving me the sailors our first output now this is the status of second output which is off all the other outputs are off to three and you have similarly for all the other outputs are off ok so if this is on you can see the status here so this is monitoring switch box utility in which you can see your inputs and outputs ok so this was the static input output check to understand the wiring principles and proper working of inputs and outputs ok now let's see the different status screens of PLC ok status screen so what we have this is to determine the pnc processes status processor ok just mind that I'm here you will see that we have two screens PLC run which shows that peels is running when peels is running it's logic is being solved that means PLC's running there's no problem with that you have any when you stop the PLC or when you put that into programming mode programming mode is like you know sometime you find this as a program or somewhere you find it stop would are the same thing when you want to program your PLC you put that in the stop mode or the program would in vegetable the logic will not be stalled it will not be running so right now if you see the current status of this PLC here its power on and it's running okay this is running here so how to stop this PLC's you open this software and you'll find here be in simulator mode gives you program mode now if i press this program mode and i press yes here now my programming is not being solved so you can see that this is off and there is no blinking going on okay there's no blinking and this is not running so if i put it into run mode again by the software here is an on board click on that click yes now you will see this is running and your blinking starts so this is just to start and stop the PLC logic by your software programming mode and the run mode okay now the next is how to download and upload the program this right now you have program already inside you want to read that so you will go to PNC transfer to PNC means transfer the logic from your software to the PLC ROM means from PLC to your system so right now we are uploading that we want the program which is already inside so the really comes from PLC then click ok press ok again so it will upload press ok so this is the logic which is running inside this is the output Q 100.000 infused by the logic which you will be doing that so this is just I'm showing how to get the larger from the PLC ok if I have to submit the logic so let's do a small logic change so instead of 1 0 0 I'm going to enter 1 0 0.01 I just change the address ok now I want to download this so what I have to do is this is step go to online click online click yes then go to the plz transfer to beers in the spine press ok and yes again and yes again so what I've done is I have to change the output now you will see here my in my IO box second output is blinking and if you see here second output is blinking here as well so that's how you change the lodging and you download it in your own agency so pretty easy just need us USB cable and the software ok so this was about PLC see the screen and uploading and downloading program in the next lessons we'll be doing some exercises about basic exercise on series and parallel lashing interlocking timers and counters to understand how to program this on PLC's so thank you so much if any you have any questions just put a comment below this video I'll get back to you thank you
