0 1 00:00:21,440 --> 00:00:22,020 Hello. 1 2 00:00:22,050 --> 00:00:27,820 In this video we are going to learn FLT and INT instructions. 2 3 00:00:28,110 --> 00:00:33,230 I will create a new project in the program area. 3 4 00:00:33,230 --> 00:00:39,170 I will create a new program and program name will be like this in the ladder diagram. 4 5 00:00:39,350 --> 00:00:50,960 We will learn how to convert integer values to floating values LD M25 and I will say flt D0 to 5 6 00:00:51,200 --> 00:00:57,800 D5 and go online to PLC and I will do a download. 6 7 00:00:57,800 --> 00:01:10,400 These instruction to PLC and I will say OK and transfer this code to PLC object code is transferring 7 8 00:01:10,520 --> 00:01:19,310 now to the plc and communication error say transfer again and it's trying to do a download 8 9 00:01:22,800 --> 00:01:34,800 it's finished now I will go online and my CPU is top situation I will say yes now D0 is 0. 9 10 00:01:34,950 --> 00:01:45,990 So we will change a value to floating value and let's change 5 to FLT I will say Okay now D0 is 10 11 00:01:46,140 --> 00:01:54,960 5 M25 will be active and then you cannot see anything in D5 why because in the 11 12 00:01:55,000 --> 00:02:08,490 view section We need to say float so as float you can see D0 was 5 and the output is 5,000 or 12 13 00:02:08,580 --> 00:02:20,580 I will say 7 and you can see it is now 7,000 and then let us expand our example a little 13 14 00:02:20,580 --> 00:02:29,880 bit go on line edit , in the online edit I will say LD M5 and 14 15 00:02:32,420 --> 00:02:34,490 FMUL -> DMUL 15 16 00:02:34,500 --> 00:02:37,500 This is floating multiplication. 16 17 00:02:37,620 --> 00:02:45,800 You can remember in the previous lessons and then D5 and D10 and D20 17 18 00:02:45,810 --> 00:02:46,800 That's okay. 18 19 00:02:46,800 --> 00:02:49,090 And then what will we do. 19 20 00:02:49,140 --> 00:03:04,550 We will change d20 value to integer and LD M10 and integer D20 to D30 then update our program 20 21 00:03:04,550 --> 00:03:05,420 line. 21 22 00:03:05,420 --> 00:03:17,090 And this is sending to plc, OK an update is completed and then I will change to value of D10 22 23 00:03:17,450 --> 00:03:26,920 to for example 5,35 floating point. 23 24 00:03:26,930 --> 00:03:31,330 We need to use comma like this then that's OK. 24 25 00:03:31,340 --> 00:03:34,930 So 7,000. 25 26 00:03:34,940 --> 00:03:39,200 Multiply by 5,350 26 27 00:03:39,680 --> 00:03:47,900 Let's check the result and M5 is activated and the result is 37,450. 27 28 00:03:48,410 --> 00:03:55,520 And then what will happen if I want to fix this value if I want to change this value to this floating 28 29 00:03:55,520 --> 00:04:00,170 value to integer value M10 set on. 29 30 00:04:00,170 --> 00:04:03,630 Then we will see D30. 30 31 00:04:03,680 --> 00:04:04,700 What will happen. 31 32 00:04:04,700 --> 00:04:05,440 Just go. 32 33 00:04:05,450 --> 00:04:05,830 View. 33 34 00:04:05,830 --> 00:04:06,530 Area. 34 35 00:04:06,670 --> 00:04:08,660 And in here automatically. 35 36 00:04:08,750 --> 00:04:13,070 And then you can see D30 now = 37 36 37 00:04:13,070 --> 00:04:14,860 What was it before. 37 38 00:04:14,870 --> 00:04:22,310 Let's take a look once floating as floating it was 37,450 38 39 00:04:22,430 --> 00:04:31,880 I will increase this value to for example 2,789 39 40 00:04:31,880 --> 00:04:40,610 And the result is you can see it 19,523 and what is the result now. 40 41 00:04:40,770 --> 00:04:46,010 Section automatically and it equals to nineteen. 41 42 00:04:46,190 --> 00:04:48,470 So what is happening. 42 43 00:04:48,470 --> 00:04:59,450 It is taking just the integer value from here after comma it is deleting completely so we can't change 43 44 00:04:59,600 --> 00:05:07,880 our values to floating with the FLT command or FLT instruction we can do our multiplications 44 45 00:05:07,940 --> 00:05:17,900 and everything in here with DEDIV/DEMUL/DESUB/DEADD as floating point math instructions 45 46 00:05:18,170 --> 00:05:27,290 and then we can fix our values with the integer or INT instruction this is how can we use floating 46 47 00:05:27,320 --> 00:05:36,770 or FLT and INT instructions in the Delta plc so I am finished for this video see you 47 48 00:05:36,980 --> 00:05:37,880 in the next video.
