1 00:00:21,470 --> 00:00:22,130 Hello. 2 00:00:22,190 --> 00:00:28,180 In this video we are going to learn Math, increment and decrement commands. 3 00:00:28,250 --> 00:00:32,120 The left side you can see at command usage. 4 00:00:32,240 --> 00:00:41,180 So in here S1 edited by S2 and the result is written to hear the output. 5 00:00:41,180 --> 00:00:51,770 So in here in example you can see when the condition is 0 is high the zero plus the time the output 6 00:00:51,800 --> 00:00:58,100 is say 2 or the result is saved or written into D 20. 7 00:00:58,130 --> 00:01:07,130 If you want to use sub command so as one minus as to the result is written two in here in here also 8 00:01:07,130 --> 00:01:12,840 you can see in on example when it's zero is activated or high. 9 00:01:13,280 --> 00:01:24,560 So from the zero B 10 is subtracted down the result is written to the twenty fourth division command 10 00:01:25,250 --> 00:01:27,610 from S1 and is 2. 11 00:01:27,800 --> 00:01:37,310 You can write here just sixteen bit values so as one divided by S2 and the result is written to hear 12 00:01:37,610 --> 00:01:38,450 the output. 13 00:01:38,540 --> 00:01:44,870 So outputs and the input should be worth data type in here. 14 00:01:44,870 --> 00:01:55,370 You can see an example x1 divided by S 2 and the result is written to the twenty four sixteen bit. 15 00:01:55,490 --> 00:02:05,930 You can see here just one words are used and if the result is higher or if you want to work with their 16 00:02:05,960 --> 00:02:07,220 high numbers. 17 00:02:07,220 --> 00:02:15,610 So imagine you are working with the 32 bits number or over thirty two thousand seven hundred sixty seven. 18 00:02:15,710 --> 00:02:24,350 So values for example you are working with the 1 million numbers a variable numbers. 19 00:02:24,650 --> 00:02:28,960 So you need to use 32 bit division. 20 00:02:29,000 --> 00:02:39,230 So in here what you write for example imagine S1 is D0 for division D0 and D1 is going to be used 21 00:02:39,520 --> 00:02:50,960 and for the as 2 if you are dividing as 1 2 for example or by the 10 so the eleven is also going to 22 00:02:50,960 --> 00:02:55,280 be used for the division and also for the output. 23 00:02:55,550 --> 00:03:07,280 So in here you can see it as one and as one plus one as two as two plus 1 and the result is D and D 24 00:03:07,460 --> 00:03:18,960 plus 1 for multiplication or multiply for the sixteen B unit use just one word and sixteen bit equals 25 00:03:18,960 --> 00:03:19,600 word. 26 00:03:19,800 --> 00:03:23,030 You remember previous lessons in here. 27 00:03:23,070 --> 00:03:34,890 The 0 multiply by the 10 and the output or result is written into the twenty for the 32 bit multiply 28 00:03:35,130 --> 00:03:44,040 or multiplication as 1 and as who is going to multiply or after multiplication the output or result 29 00:03:44,040 --> 00:03:53,280 is written to here but like here we are not going to use just one word they will use S1 and as one plus 30 00:03:53,280 --> 00:04:03,870 one as two as two plus 1 and D Day plus 1 because this is just sixteen bit but this is also sixteen 31 00:04:03,870 --> 00:04:09,570 bit but totally thought it to be means uh to work. 32 00:04:09,720 --> 00:04:19,160 So they will use 32 bit multiplication just two words and the next page we will see increment common. 33 00:04:19,230 --> 00:04:29,280 So when the condition goes high each time this value is going to be upside plus 1 each time one will 34 00:04:29,280 --> 00:04:41,070 be added to this value all the zeros value the increase by 1 1 0 goes from off to on each time. 35 00:04:41,070 --> 00:04:52,140 And if these euro is 16 b we will use these values if these euro is 32 bit these values will be range 36 00:04:52,140 --> 00:05:02,400 of our data register for decrement command we will go lower this time so each time these 0 minus 1 will 37 00:05:02,400 --> 00:05:07,960 be the value will be mu minus or subtract by 1. 38 00:05:08,070 --> 00:05:21,180 And when it 0 goes from off to on for example the 0 is 10 so x 0 is activated the 0 will be 9 and after 39 00:05:21,420 --> 00:05:25,380 0 is activated again the 0 will be a. 40 00:05:25,560 --> 00:05:29,510 And these applications and practices that we need to see. 41 00:05:29,760 --> 00:05:39,300 So let's go ISPsof and create a new project and new project is created and programs come here and 42 00:05:39,480 --> 00:05:49,140 right click a new a new program is opened and I will create a device monitor table also and lets say 43 00:05:49,170 --> 00:05:54,830 Okay and let's go programs and let's do some examples. 44 00:05:54,840 --> 00:06:06,460 Ld m0 and at D0 to D4 and in here one more network and LD M1. 45 00:06:06,920 --> 00:06:19,510 and for the subtract sub d10 D12 and D14 I will do it like this. 46 00:06:19,510 --> 00:06:29,930 And in here I will say LD M22 and let s do multiplication add D22 D24 47 00:06:30,340 --> 00:06:41,550 and one more LD M3 and multiplication 32 bit that we are going to use now D32 and D34 48 00:06:41,550 --> 00:06:54,870 ups this is not okay and let's take a look once two division LD 5 and division 49 00:06:55,200 --> 00:07:07,140 D40 D42 D44 will be resolved and ld M6 division 32bit will be 50 00:07:07,140 --> 00:07:18,300 D50 D52 and d54 and for the increment and decrement commands LD M7 and 51 00:07:18,590 --> 00:07:33,930 increment D60 and for decrement command LD M8 and decrement D70 so let s go 52 00:07:33,930 --> 00:07:44,250 online and let's do some practice is about our commands and learn them all effectively and how 53 00:07:44,250 --> 00:07:47,480 can we can use them how we can monitor them. 54 00:07:47,780 --> 00:07:49,470 Let's let's take a look them all. 55 00:07:49,620 --> 00:07:59,970 First of all ADD command and I will just check our CPU is now run situation and I will open my 56 00:08:00,040 --> 00:08:05,130 online edit button or activate my online Edit Also and I will change. 57 00:08:05,130 --> 00:08:09,170 This will do is say 5. 58 00:08:09,690 --> 00:08:13,130 Let's say this change present value to a. 59 00:08:13,600 --> 00:08:14,400 I'm waiting. 60 00:08:14,400 --> 00:08:25,790 The output should be 13 so set on the condition on and our output is 13 four subtract command from 20. 61 00:08:25,980 --> 00:08:28,320 Let's subtract for example. 62 00:08:28,500 --> 00:08:32,040 And 7 and I'm still waiting. 63 00:08:32,040 --> 00:08:42,450 The output of this condition should be 13 set or so it is subtracted subtracted from the 10. 64 00:08:42,480 --> 00:08:43,240 --- 65 00:08:43,250 --> 00:08:47,310 D 12 so 20 - 7 = 13 . 66 00:08:47,640 --> 00:08:56,240 So multiplication let's say 5 multiply by for example 9 67 00:08:56,280 --> 00:08:58,020 So output should be. 68 00:08:58,320 --> 00:09:04,530 I'm waiting that 45 and is activated and 45 is our result. 69 00:09:04,530 --> 00:09:09,370 So what about the 32 bit multiplication. 70 00:09:09,510 --> 00:09:15,210 So let's change this value to for example 1000. 71 00:09:15,450 --> 00:09:19,590 So let's change this value to 5000 72 00:09:19,800 --> 00:09:26,040 So I'm waiting the output should be five million and set on. 73 00:09:26,580 --> 00:09:28,700 So now let's take a look. 74 00:09:28,830 --> 00:09:34,280 The output is 19264 75 00:09:34,530 --> 00:09:38,850 But they are expecting the result should be 5 million. 76 00:09:38,850 --> 00:09:39,510 Why. 77 00:09:39,510 --> 00:09:40,590 Let's take a look. 78 00:09:40,650 --> 00:09:45,960 Monitor table and let's come here and the identifiers. 79 00:09:45,960 --> 00:09:47,990 I will take a look two registers. 80 00:09:48,080 --> 00:09:48,710 Okay. 81 00:09:48,870 --> 00:09:51,930 The 30 at 10 million. 82 00:09:52,230 --> 00:09:53,610 So let's take a look. 83 00:09:53,610 --> 00:09:54,960 One thousand. 84 00:09:55,170 --> 00:09:57,500 Multiply by five thousand. 85 00:09:57,660 --> 00:10:00,330 And the result is a 32 bit. 86 00:10:00,390 --> 00:10:01,020 Imagine. 87 00:10:01,080 --> 00:10:02,750 Let's look let's focus here. 88 00:10:02,760 --> 00:10:03,630 5 million. 89 00:10:03,690 --> 00:10:07,740 But we are saying it in the eyes piece of 19. 90 00:10:08,130 --> 00:10:09,810 264. 91 00:10:09,810 --> 00:10:11,580 So let's open. 92 00:10:11,580 --> 00:10:15,450 Calculator and let's take a look once. 93 00:10:15,480 --> 00:10:21,050 How can we get there reach five million value after thirty. 94 00:10:21,050 --> 00:10:24,450 The 32 bit multiplication. 95 00:10:24,550 --> 00:10:30,230 So now 2^16 bit 96 00:10:30,330 --> 00:10:38,170 So we can we can get complete numbers and full numbers or maximum numbers for one word. 97 00:10:38,190 --> 00:10:43,150 So this is the value of one word can get maximum value. 98 00:10:43,170 --> 00:10:51,840 So how many or what is the value of these 35 or carry value of our multiplication. 99 00:10:51,870 --> 00:10:56,750 So this is 76, multiplied by 76 100 00:10:56,880 --> 00:11:07,770 And what we have in these 34 the rest of all value 19264 + 101 00:11:08,390 --> 00:11:12,790 sorry --- 102 00:11:13,050 --> 00:11:23,760 This is my mistake again and multiply by 76 2^16 103 00:11:23,880 --> 00:11:35,030 multiply by 76 equals and + 19264 104 00:11:35,240 --> 00:11:40,300 equals five million. 105 00:11:40,340 --> 00:11:53,450 So after division you can see the D0 the D will use of us was D 34 D34 and 106 00:11:53,650 --> 00:12:04,340 D34+1 means D35 is includes our complete multiplication so multiplication 107 00:12:04,340 --> 00:12:06,770 result is +5000000 108 00:12:06,860 --> 00:12:15,500 So already we have five million in here and let's take a look once to division for example let's divide 109 00:12:15,920 --> 00:12:23,130 40 by 4 so the result should be ten. 110 00:12:23,210 --> 00:12:30,190 Let's take a look once said on M5 contact and our result is done. 111 00:12:30,410 --> 00:12:32,000 So this is the easy. 112 00:12:32,000 --> 00:12:46,520 So what about 32 bit division so D50 let's change this present value for example 1 0 2 3 5 6 7 this 113 00:12:46,520 --> 00:12:51,970 is just an example I will to write this one. 114 00:12:52,040 --> 00:13:03,080 So 32bit but it seems negative volume so how can we give and number two it just I'm not 115 00:13:03,080 --> 00:13:08,970 used to in here as word I will just use like this. 116 00:13:09,250 --> 00:13:09,850 Okay. 117 00:13:10,070 --> 00:13:20,270 This is ten million two hundred fifty four thousand three hundred and sixty five and to show you the 118 00:13:20,780 --> 00:13:30,200 fifty two will be five but first I will update my project and project updated so let's change this to 119 00:13:30,620 --> 00:13:31,490 for example 120 00:13:35,390 --> 00:13:48,570 an M6 is going to be activated so the result is fifteen 374 so I will do it I will do my calculation 121 00:13:48,570 --> 00:13:58,710 in here so this is our result let's fifteen thousand three hundred and seventy four multiplied by two. 122 00:13:59,000 --> 00:14:03,960 But look this is not our as one module so what happened in here. 123 00:14:04,010 --> 00:14:05,320 Let's take a look. 124 00:14:05,440 --> 00:14:05,870 The 125 00:14:08,990 --> 00:14:13,220 deep 40 and 10 number is in here. 126 00:14:13,880 --> 00:14:28,540 Um it started in here but what was out the the 58 and the 54 that I need to take a look. 127 00:14:29,260 --> 00:14:33,020 Sorry for the deep deep 40 was not okay. 128 00:14:33,080 --> 00:14:36,060 The 50 and 10 molar. 129 00:14:36,250 --> 00:14:37,470 Let's show us. 130 00:14:37,570 --> 00:14:38,610 Okay. 131 00:14:38,740 --> 00:14:40,850 This is our 132 00:14:40,960 --> 00:14:44,160 This is D fifty four A's. 133 00:14:44,200 --> 00:14:53,150 Let's take a look wants to in here in our result and we need to focus to carry 134 00:14:53,410 --> 00:14:55,780 What is the value of the D55 135 00:14:55,880 --> 00:14:57,060 -- 136 00:14:57,100 --> 00:15:00,770 So come here and check once this is out. 137 00:15:00,890 --> 00:15:04,120 D55 value 78 138 00:15:04,180 --> 00:15:15,190 This is our carry value so we need to reach a complete D value as one value so we divided ten million 139 00:15:15,190 --> 00:15:20,890 two hundred and fifty four thousand two hundred and sixty five followed by two. 140 00:15:20,980 --> 00:15:24,670 But how can we go to this value again. 141 00:15:24,670 --> 00:15:28,460 So let's calculate it again in here. 142 00:15:28,540 --> 00:15:35,740 I will use my calculator and two exponential sixteen equals this value. 143 00:15:35,740 --> 00:15:41,990 This is complete value of one word multiply by seventy eight. 144 00:15:42,050 --> 00:15:51,280 These were you and what we need to plus fifteen. 145 00:15:51,280 --> 00:15:53,400 Three hundred and seventy four. 146 00:15:53,400 --> 00:15:57,740 Look this is our value. 147 00:15:57,930 --> 00:16:00,720 let's check in here. 148 00:16:00,720 --> 00:16:11,470 You can see you can see five million one hundred twenty seven and one hundred thousand one hundred 149 00:16:11,470 --> 00:16:12,600 and eighty two. 150 00:16:12,640 --> 00:16:16,390 This is 32bit result. 151 00:16:16,390 --> 00:16:17,660 So this is our result. 152 00:16:17,920 --> 00:16:30,580 So the carry inside of D55 is shows us how can we use 32Bit value inside of 153 00:16:30,580 --> 00:16:32,020 the plc projects. 154 00:16:32,080 --> 00:16:42,940 So when you do a division or multiplication with the higher values , higher value numbers or data registers 155 00:16:43,300 --> 00:16:51,330 you need to check ones to the upper data registers inside of your plc projects. 156 00:16:51,370 --> 00:16:59,230 So let's go back to our program and let's take a look once to increment and decrement commands M7 is 157 00:16:59,230 --> 00:16:59,590 on. 158 00:17:00,220 --> 00:17:08,350 Look this is always on and this is incrementing by one always and always and always. 159 00:17:08,410 --> 00:17:17,860 So we need to we need to stop this and we need to increment our d60 value one by one how can we do 160 00:17:17,860 --> 00:17:18,390 this. 161 00:17:18,610 --> 00:17:26,590 We can do it like this for example if we say this is our rising edge and this is also a rising edge and 162 00:17:26,950 --> 00:17:38,770 let's take a look once and also add one more contact let's say OR contact OR M0 like this and 163 00:17:38,920 --> 00:17:52,290 I will use this one to here to show you and in here I need to M8 or M10 then this should be M9 because 164 00:17:52,310 --> 00:18:05,410 M8 is used and again in here I will use it , I will update my project and okay update the program 165 00:18:05,410 --> 00:18:08,210 line okay and it's completed. 166 00:18:08,590 --> 00:18:17,340 So now imagine this is activated then like and always on this is incrementing all. 167 00:18:17,530 --> 00:18:29,520 But now look and so on is activated and it is incremented just once because this is just the rising 168 00:18:29,530 --> 00:18:39,490 h what happens M9 is goes always on just once you see we are just giving a one pulse and it's increasing 169 00:18:39,850 --> 00:18:52,560 just one for the decrement let's say our value is for example 10 so look set on just once it is decrement 170 00:18:52,560 --> 00:19:02,940 it as one or 10 is always on but it is just decrement it just once just one pulse so we can use these 171 00:19:02,940 --> 00:19:11,250 commands with the rising edge or falling edge contact and also with the just normal contact but with the 172 00:19:11,580 --> 00:19:21,900 up the same like rising edge or falling edge contacts then we can increment or decrement our data registers 173 00:19:21,920 --> 00:19:31,680 one by one each pulse just one and one and one is sequentially and what happens if I put here for 174 00:19:31,680 --> 00:19:43,920 example or M1011 this is can millisecond clock pulse so let's take a look once what 175 00:19:43,920 --> 00:19:47,160 will happen inside of the 60. 176 00:19:47,490 --> 00:19:57,180 Look it's incrementing so let's give a pulse 13 1s clock pulse and each one second we 177 00:19:57,180 --> 00:19:59,640 need to look what will happen. 178 00:19:59,790 --> 00:20:07,180 You see it is not incrementing also just sequentially one and one plus one plus one. 179 00:20:07,180 --> 00:20:11,440 No just this is going on high. 180 00:20:11,450 --> 00:20:14,640 Deep down you are going to remember previous lessons. 181 00:20:14,830 --> 00:20:18,870 Just how 1sec goes high just half sec. 182 00:20:18,950 --> 00:20:20,440 It's incrementing a lot. 183 00:20:20,440 --> 00:20:27,810 Also so the solution is possible solutions like these. 184 00:20:28,030 --> 00:20:31,080 Again I need to select it. 185 00:20:31,630 --> 00:20:33,840 I think to change. 186 00:20:33,860 --> 00:20:38,650 Okay just should come here. 187 00:20:38,770 --> 00:20:39,200 Okay 188 00:20:42,440 --> 00:20:47,650 I will use it to here it is possible the same thing. 189 00:20:47,820 --> 00:20:52,670 And sent this project to the plc 190 00:20:52,680 --> 00:20:54,170 An update is completed. 191 00:20:54,180 --> 00:20:59,520 You see it is incrementing one by one each. 192 00:20:59,640 --> 00:21:04,030 Second each and 1013 goes high. 193 00:21:04,050 --> 00:21:06,310 It is incrementing 1. 194 00:21:06,390 --> 00:21:09,370 So thank you for this video. 195 00:21:09,390 --> 00:21:10,980 I'm finished. 196 00:21:11,160 --> 00:21:13,250 So see you in the next video.
