0 1 00:00:21,480 --> 00:00:22,160 Hello. 1 2 00:00:22,200 --> 00:00:27,760 Today we are going to learn contact types and start up to basic commands. 2 3 00:00:27,810 --> 00:00:36,630 So in this page you can see AND contact and ANDI contact and OR contact types and also rising EDGE and 3 4 00:00:36,630 --> 00:00:41,130 the falling edge and set output and the reset output. 4 5 00:00:41,130 --> 00:00:50,490 So for these contacts to learn them all it's open ISPsoft and let's create the project and the simulator 5 6 00:00:50,520 --> 00:00:52,190 with the simulator help. 6 7 00:00:52,320 --> 00:00:55,460 We are going to learn them all effectively. 7 8 00:00:55,560 --> 00:01:05,970 So in the ISPSoft software come here and click new and I will type it test application and our 8 9 00:01:05,970 --> 00:01:11,660 controller type is going to be DVP and plc type is going to be ss2 9 10 00:01:11,850 --> 00:01:13,060 And let's press. 10 11 00:01:13,080 --> 00:01:14,380 OK. 11 12 00:01:14,430 --> 00:01:15,400 And this now. 12 13 00:01:15,420 --> 00:01:24,140 And now let's open a program a new program that's created a name POU means program organization unit 13 14 00:01:24,540 --> 00:01:35,460 so we can say it just the program program name is going to be test application and our programming language 14 15 00:01:35,490 --> 00:01:45,210 is going to be a ladder diagram and its type in here as common test application for udemy. 15 16 00:01:45,560 --> 00:01:47,290 And OK. 16 17 00:01:47,520 --> 00:01:55,650 This is our programming page and it's opened and in here we will serial contact. 17 18 00:01:55,680 --> 00:02:02,220 We will put in here will serial contacts we can add a contact to click in here just the contact and 18 19 00:02:02,220 --> 00:02:09,990 we can come here and just click left mouse twice and it will add contacts like these. 19 20 00:02:09,990 --> 00:02:19,650 And if you want to just to write a plc programs easily you can come here to red and black dots 20 21 00:02:19,740 --> 00:02:30,690 in here in this area you can click twice to left side LD M0 and LD M1 and let's put in here one 21 22 00:02:30,720 --> 00:02:43,380 output and out Y0 so M1 and M0 and Y1 is serial contacts and also insert one extra network 22 23 00:02:43,810 --> 00:02:50,690 and LD M3 or M3 23 24 00:02:50,840 --> 00:02:55,460 So this is our parallel contact or OR contact. 24 25 00:02:55,730 --> 00:03:01,180 So that's put in here or contacts. 25 26 00:03:01,240 --> 00:03:07,960 So lets add here one more output , OUT Y1 and insert one more network. 26 27 00:03:08,500 --> 00:03:15,740 LD M4 and let's put in here inverse contact or not contact LDI M5 27 28 00:03:15,790 --> 00:03:31,770 put here an output, out Y2 and insert one more network put in here not contact. 28 29 00:03:31,770 --> 00:03:39,660 We can type like this not contact and in here we can add to. 29 30 00:03:39,660 --> 00:03:43,700 We can learn in this network to set. 30 31 00:03:43,690 --> 00:03:44,160 command 31 32 00:03:46,520 --> 00:03:54,170 And also we are going to learn now how to add rising edge Contract type so LDP 32 33 00:03:54,250 --> 00:03:54,860 ldp 33 34 00:03:55,040 --> 00:03:57,170 This is our rising edge contact. 34 35 00:03:57,170 --> 00:03:58,020 command. 35 36 00:03:58,460 --> 00:04:07,050 And we can add a contact as the auxiliary contact M6 and output SET Y3 36 37 00:04:07,200 --> 00:04:08,100 Y3 37 38 00:04:08,130 --> 00:04:11,030 And one more network. 38 39 00:04:11,040 --> 00:04:19,830 Now let's insert in this network to following edge contact LDF, F means falling edge. 39 40 00:04:19,930 --> 00:04:32,350 So not an output just an auxiliary relay M7 and reset Y3 40 41 00:04:32,450 --> 00:04:38,960 So let's simulate these things all click in here and compile our project. 41 42 00:04:38,960 --> 00:04:47,030 There is no error and download our project to the simulator and press transfer button and say yes and 42 43 00:04:47,030 --> 00:04:50,540 now object is transferring to the running state ,Yes. 43 44 00:04:50,570 --> 00:04:52,130 I want to go back to running state. 44 45 00:04:52,160 --> 00:04:53,780 If you do it ... 45 46 00:04:53,810 --> 00:04:58,850 If you do it first time so it can be like this. 46 47 00:04:58,880 --> 00:05:03,690 So plc or simulator can be stopped or could be stopped. 47 48 00:05:03,710 --> 00:05:05,870 So look what will happen. 48 49 00:05:05,890 --> 00:05:09,610 M0 and M1 is active but there is no output. 49 50 00:05:09,620 --> 00:05:13,210 Why because our PLC or simulator is stopped. 50 51 00:05:13,310 --> 00:05:14,930 So you need to come here. 51 52 00:05:14,930 --> 00:05:19,540 You need to select run, run situation now activated. 52 53 00:05:19,610 --> 00:05:23,090 Then we can see our output is activated. 53 54 00:05:23,150 --> 00:05:24,680 So this is our serial contact. 54 55 00:05:24,680 --> 00:05:27,740 What happens for the serial contact. 55 56 00:05:27,740 --> 00:05:28,970 serial contacts. 56 57 00:05:28,970 --> 00:05:31,280 All of them must be on for the output. 57 58 00:05:31,280 --> 00:05:38,560 So M0 is active but it is not enough to activate our output. 58 59 00:05:38,810 --> 00:05:43,030 M1 must be active also for OR contact two. 59 60 00:05:43,030 --> 00:05:47,480 Or there can be a lot of contacts as parallel. 60 61 00:05:47,480 --> 00:05:49,810 One of them must be active. 61 62 00:05:49,820 --> 00:05:51,080 So we have an output. 62 63 00:05:51,350 --> 00:05:55,650 So M3 is active also still we have an output M2 is off. 63 64 00:05:55,670 --> 00:06:00,830 We have still active output ,M3 is of our output. 64 65 00:06:00,830 --> 00:06:03,750 this activated for the not contact. 65 66 00:06:03,980 --> 00:06:05,200 M4 for example. 66 67 00:06:05,210 --> 00:06:12,170 This is just a normally open contact and M5 is normally close contact and these conditions 67 68 00:06:12,170 --> 00:06:12,620 are okay. 68 69 00:06:12,620 --> 00:06:21,490 We have an output but what happens M5 goes on set on our output is off M5 set off. 69 70 00:06:21,530 --> 00:06:28,720 We have an output M4 is off our output is gone for the M6 for a set command. 70 71 00:06:28,820 --> 00:06:31,150 This is just the rising edge. 71 72 00:06:31,190 --> 00:06:40,110 If somebody pressed a button then that moment suddenly after the button is activated it is just a square 72 73 00:06:40,230 --> 00:06:41,290 wave. 73 74 00:06:42,170 --> 00:06:44,270 Beginning of the square wave 74 75 00:06:44,300 --> 00:06:48,790 It will give an output so suddenly Y3 set. 75 76 00:06:49,070 --> 00:06:51,080 So we have a set output. 76 77 00:06:51,080 --> 00:06:54,580 What happens if M6 released set off. 77 78 00:06:54,590 --> 00:07:02,960 So we have still output M7 is active but we have still output y3 still set. 78 79 00:07:02,960 --> 00:07:03,600 Why. 79 80 00:07:03,650 --> 00:07:06,820 Because M7 is falling edge contact. 80 81 00:07:07,070 --> 00:07:13,180 So after on to off suddenly our output is gone. 81 82 00:07:13,190 --> 00:07:15,940 So what happens for the plc programming. 82 83 00:07:15,970 --> 00:07:24,230 when you want to latch some circuits or let's say you need latched circuits or latched programming 83 84 00:07:24,230 --> 00:07:33,650 concepts so also you need online edit to control your plc to because of 84 85 00:07:33,650 --> 00:07:39,160 Machine can be running and you maybe you don't want to stop your machine. 85 86 00:07:39,230 --> 00:07:42,570 So what can you do so you can come here. 86 87 00:07:42,680 --> 00:07:50,930 You can activate online edit mode, now online edit mode is active but for online edit you cannot add 87 88 00:07:50,990 --> 00:07:53,540 any variable to in here. 88 89 00:07:53,540 --> 00:08:00,980 I will also while you are online you cannot do this but I will add some variables to understand our 89 90 00:08:00,980 --> 00:08:05,810 concepts or our lesson so I will stop our plc. 90 91 00:08:05,810 --> 00:08:10,340 I will come here to left click twice identifier. 91 92 00:08:10,520 --> 00:08:16,470 Let's give it a name , start name given it, to start button. 92 93 00:08:16,490 --> 00:08:19,080 This type will be bool okay. 93 94 00:08:19,190 --> 00:08:29,450 This is just a variable and stop button should be bool and we want to turn our motor forward. 94 95 00:08:29,810 --> 00:08:37,300 So let's give a name motor forward and type should be bool okay. 95 96 00:08:37,760 --> 00:08:42,060 And go on line. 96 97 00:08:42,200 --> 00:08:43,570 Now we are on line. 97 98 00:08:43,610 --> 00:08:53,690 Our Plc in run situation and I will open our online edit mode and insert network and write 98 99 00:08:53,960 --> 00:09:05,340 plc programs for the latching circuit and also I will put a note here latching circuit okay. 99 100 00:09:07,800 --> 00:09:20,610 LDP so when somebody pressed the start button start button and if there is no stop button is active 100 101 00:09:20,820 --> 00:09:23,520 or never pressed stop button. 101 102 00:09:23,520 --> 00:09:25,460 Imagine like this. 102 103 00:09:25,510 --> 00:09:35,490 LDI stop button motor is going to turn forward 103 104 00:09:35,740 --> 00:09:38,890 OUT Motorforward also in here. 104 105 00:09:39,180 --> 00:09:50,320 I will add one OR contact like this and this will be motor forward. 105 106 00:09:50,340 --> 00:09:51,940 This will latch our circuit. 106 107 00:09:52,310 --> 00:09:56,040 Okay send changes to our plc. 107 108 00:09:56,170 --> 00:09:56,550 Okay. 108 109 00:09:56,560 --> 00:09:59,700 There is no error an update program online. 109 110 00:09:59,920 --> 00:10:01,690 Update is completed. 110 111 00:10:01,690 --> 00:10:03,880 Somebody press that button. 111 112 00:10:03,880 --> 00:10:08,020 Now our motor is turning forward pressed and released. 112 113 00:10:08,080 --> 00:10:09,180 Start button. 113 114 00:10:09,400 --> 00:10:17,410 So if you want to stop your motor you need to press stop button press once and release and motor forward. 114 115 00:10:18,390 --> 00:10:19,980 Is disactivated now. 115 116 00:10:20,310 --> 00:10:25,160 So this latched circuit is disactivated also. 116 117 00:10:25,170 --> 00:10:32,520 And suddenly somebody pressed against start button and released Motor is still turning forward again 117 118 00:10:32,540 --> 00:10:38,550 and stop button is pressed and motor forward finished or stopped. 118 119 00:10:38,910 --> 00:10:43,270 So this is the example of the latching circuits in this video. 119 120 00:10:43,500 --> 00:10:50,550 We learned how to do online it it how to create a new plc project how to insert the networks and 120 121 00:10:50,550 --> 00:10:56,670 the serial contacts and the parallel contacts and how to set and reset and the falling edge and the 121 122 00:10:56,670 --> 00:11:05,470 rising edge and latching circuits and how to create variables for the basic programming concepts. 122 123 00:11:05,610 --> 00:11:08,800 So we are finished for this video. 123 124 00:11:08,880 --> 00:11:10,200 See you in the next video.
