0 1 00:00:21,510 --> 00:00:22,080 Hello. 1 2 00:00:22,110 --> 00:00:30,570 In this video we are going to learn WSFR or WSFL shifting data instruction in the previous educations 2 3 00:00:30,600 --> 00:00:39,210 we learned SFTR we shifted bits but these instructions is going to help us to shift datas 3 4 00:00:39,240 --> 00:00:42,850 WSFR means right and WSFL left. 4 5 00:00:42,870 --> 00:00:44,190 You already learned it. 5 6 00:00:44,340 --> 00:00:51,380 It is s means initial device which value is shifted an initial device in which value is shifted. 6 7 00:00:51,380 --> 00:00:57,230 Also D and N1 ,it is still remember it ,length is really important. 7 8 00:00:57,270 --> 00:01:04,290 We worked with D4 in SFTR command but in here N1 is still same and N2 is number 8 9 00:01:04,290 --> 00:01:05,810 of bits forming a group. 9 10 00:01:05,860 --> 00:01:06,850 So. 10 11 00:01:06,900 --> 00:01:10,050 R means It is going to shift from left to right L means. 11 12 00:01:10,050 --> 00:01:13,080 It is going to shift from left to right. 12 13 00:01:13,110 --> 00:01:14,400 That's all. 13 14 00:01:14,420 --> 00:01:15,630 --- 14 15 00:01:15,630 --> 00:01:17,930 Right to Left from left to right. 15 16 00:01:18,010 --> 00:01:25,260 And I said wrongly R means we will shift to the right side and L means we will shift to the left side. 16 17 00:01:25,320 --> 00:01:29,010 So that moment we are starting from the right to the left. 17 18 00:01:29,280 --> 00:01:36,570 So in the ISPsoft I will create similar very basic example for you and you will understand how can we 18 19 00:01:36,570 --> 00:01:43,070 use WSFR command or WSFRP - P means pulse contact. 19 20 00:01:43,110 --> 00:01:48,550 Again I am telling that I will use in this project pulse contact. 20 21 00:01:49,050 --> 00:01:55,420 Let's create a new project and program 0 is creating now in. 21 22 00:01:55,860 --> 00:02:03,840 In this project I will use again LD ex. x0.5 22 23 00:02:03,840 --> 00:02:14,080 This is because as series CPU types and WSFRP 23 24 00:02:14,090 --> 00:02:20,970 This is our instruction and this moment I will add here x0.6 24 25 00:02:21,070 --> 00:02:28,780 And now remember we used the rising edge in SFTR command but this moment we are not 25 26 00:02:28,780 --> 00:02:34,420 using rising edge for the x0.5 because we use pulse contact in here. 26 27 00:02:34,420 --> 00:02:38,830 And how many data that w are going to shift in this project or in this example. 27 28 00:02:38,860 --> 00:02:44,470 I will say 5 and each time how many data is going to shift one by one. 28 29 00:02:44,590 --> 00:02:45,480 So this is one. 29 30 00:02:45,580 --> 00:02:50,970 So we will read the results from that let's say D20. 30 31 00:02:51,220 --> 00:02:51,920 That's all. 31 32 00:02:52,000 --> 00:02:56,430 And now we can send this project to simulator. 32 33 00:02:56,680 --> 00:03:08,160 but now X0.6 data type is doesn't match up because now I made a mistake because 33 34 00:03:08,190 --> 00:03:16,400 now what we are doing data shifting we are shifting data so x.6(bool) 34 35 00:03:16,710 --> 00:03:19,460 Bu this is not a data. 35 36 00:03:19,470 --> 00:03:20,450 This is not a word. 36 37 00:03:20,460 --> 00:03:27,310 So we need to put here word value so we will read word values from d0. 37 38 00:03:27,480 --> 00:03:38,120 Let's say like this I will go to my slide and I will say to for example the line is moving forward and 38 39 00:03:38,120 --> 00:03:40,700 we have here boxes. 39 40 00:03:40,930 --> 00:03:48,020 Then we have a value of these boxes but which value we are getting. 40 41 00:03:48,020 --> 00:03:59,680 For example weight value from these boxes in here from the Loadcell so and than according to weight 41 42 00:04:00,040 --> 00:04:06,910 we are shifting or we are separating these boxes to the right or left or front and etc. 42 43 00:04:06,940 --> 00:04:13,900 This is according to your mechanical system and then we need to get these weights from here and we need 43 44 00:04:13,900 --> 00:04:16,450 to send it to here immediately. 44 45 00:04:16,780 --> 00:04:22,900 So this is our project structure or this is our examples structure. 45 46 00:04:22,900 --> 00:04:25,080 I will compile this project. 46 47 00:04:25,120 --> 00:04:27,210 Now we are okay and done. 47 48 00:04:27,580 --> 00:04:36,310 I will go online to plc and I want to do a download this project say transfer now it's transferring 48 49 00:04:36,700 --> 00:04:39,360 and I want to go back to running state. 49 50 00:04:39,460 --> 00:04:48,430 Now we are okay so we will shift five data and we will read these five data from starting from D20 50 51 00:04:48,910 --> 00:05:00,190 till D25 and then let's change it D0 will be 5 and I will increase it one by one and force it 51 52 00:05:00,310 --> 00:05:13,330 on and force and off and the next one should be six and set on or force on and off next one will be 52 53 00:05:14,110 --> 00:05:14,970 seven. 53 54 00:05:15,640 --> 00:05:20,880 And again four set on set off. 54 55 00:05:20,950 --> 00:05:33,000 This was 3. and this will be fourth one and set on and off and this will be fifth one. 55 56 00:05:33,220 --> 00:05:39,290 And this is the end and set on set off. 56 57 00:05:39,290 --> 00:05:44,000 Now go to the device monitor table and add here left click. 57 58 00:05:44,110 --> 00:05:45,980 It is starting from D20. 58 59 00:05:45,980 --> 00:05:48,620 Just five value so you can see it in here. 59 60 00:05:48,690 --> 00:05:52,520 D20 is now five and d 21 is six. 60 61 00:05:52,530 --> 00:05:56,090 D22 is 7 and 8 and 9. 61 62 00:05:56,120 --> 00:05:57,060 What happened. 62 63 00:05:57,110 --> 00:06:03,210 We shifted five data five word data to from. 63 64 00:06:03,220 --> 00:06:07,140 from left to right. 64 65 00:06:07,150 --> 00:06:09,160 So what happened. 65 66 00:06:09,160 --> 00:06:16,380 We started with five and we ended with the nine so completely it is shifted correctly. 66 67 00:06:16,540 --> 00:06:27,160 And if I go to my program area and if I say again set on and fourth set of what happened now it has 67 68 00:06:27,160 --> 00:06:36,270 shifted it was 9 device monitor table it is still trying to shift with the 5 and 5 it is writed 68 69 00:06:36,340 --> 00:06:42,080 immediately to D24 why because we are just working with the 5 data 69 70 00:06:42,100 --> 00:06:52,080 The length is 5 because of this it is running with the D 20 till D25 so the 24 is the last one. 70 71 00:06:52,190 --> 00:07:03,800 So it is writing to first D24 and d 23 so I can just write here to understand D24 and then it is writing 71 72 00:07:03,800 --> 00:07:14,990 D 23 22 21 and 20 and that moment this is the fourth one and then again it is going to be equal to 72 73 00:07:15,230 --> 00:07:22,780 my line because the first value was in the D24 and the second value is activated or second time it 73 74 00:07:22,780 --> 00:07:30,780 is activated and first value was in the D 23 and the third time we activated the first value is now 74 75 00:07:31,150 --> 00:07:38,880 twenty two and the fourth time in the D 21 and the fifth time we activated x0.5 and 75 76 00:07:38,880 --> 00:07:46,380 that moment first value is came to D20 it is working like this and it is wsfr command if you 76 77 00:07:46,380 --> 00:07:54,540 delete p - pulse contact from here for example like this you need put here rising edge like this 77 78 00:07:54,540 --> 00:08:02,400 So this is how wsfr command is working or how we are shifting the datas or it is coming from the 78 79 00:08:02,400 --> 00:08:09,240 loadcell or coming from your recipes or something like this and you can shift them all with the just 79 80 00:08:09,320 --> 00:08:14,280 with one contact with according to your parameters from here what was it. 80 81 00:08:14,280 --> 00:08:22,110 It is where we are reading from the values and how many data the length of the data and how many 81 82 00:08:22,140 --> 00:08:30,210 we are going to shift each time when these command is the instruction is worked or run and where 82 83 00:08:30,210 --> 00:08:37,530 we are going to get the results from D ,these are all for the wsfr command or you can just try it 83 84 00:08:37,530 --> 00:08:47,790 yourself WSFL or WSFLP or with pulse contact command with yourself to understand this command how 84 85 00:08:47,790 --> 00:08:50,880 can we use it how can we work with it. 85 86 00:08:50,880 --> 00:08:57,060 But this is also for the production lines this is really important instruction and finished for this 86 87 00:08:57,060 --> 00:08:59,090 video see you in the next video.
