Hello.
1

2
00:00:22,020 --> 00:00:26,790
In this video we are going to learn ST operators this is really important.
2

3
00:00:26,970 --> 00:00:34,890
While we are writing ST  or structure text programming in the Delta plc you can see precedence
3

4
00:00:35,400 --> 00:00:37,100
is highest one.
4

5
00:00:37,260 --> 00:00:43,680
It is a parenthesis the parenthetical part of an expression is calculated first.
5

6
00:00:43,680 --> 00:00:45,120
This is important.
6

7
00:00:45,120 --> 00:00:49,740
It is coming from the Math and you can see the expression example in here.
7

8
00:00:49,950 --> 00:00:51,100
So what will happen.
8

9
00:00:51,200 --> 00:00:53,100
Six multiplied by three.
9

10
00:00:53,110 --> 00:00:55,500
No this is not going to happen first.
10

11
00:00:55,590 --> 00:01:03,340
D0 +6 will be edit and then it is multiplying by 3.
11

12
00:01:03,430 --> 00:01:06,470
For example Exponentian
12

13
00:01:06,520 --> 00:01:15,280
This is the second highest precedence so for this what will we do with exponentiation
13

14
00:01:15,880 --> 00:01:19,000
2.0 exponent 5.0.
14

15
00:01:19,090 --> 00:01:21,360
So it will be equal to 32.
15

16
00:01:21,370 --> 00:01:24,570
So it is also .
16

17
00:01:24,670 --> 00:01:32,630
This is similar to you maybe 3.2E+1 equals 3.2x10
17

18
00:01:33,010 --> 00:01:36,930
3.2 x10 = 32
18

19
00:01:36,970 --> 00:01:37,650
This is ten.
19

20
00:01:37,660 --> 00:01:39,480
This is 3.2
20

21
00:01:39,480 --> 00:01:42,120
It equals to 32
21

22
00:01:42,220 --> 00:01:44,130
And also this is not logical.
22

23
00:01:44,130 --> 00:01:46,150
The logical negation.
23

24
00:01:46,150 --> 00:01:53,410
So it is similar with the inverted contact in the Delta plc and also plus and minus.
24

25
00:01:53,410 --> 00:01:58,900
Addition and subtraction you can see it expressions in here for example AND contact.
25

26
00:01:59,860 --> 00:02:09,400
This is our contact normally open and this is and contact or contact that we used in the Delta plcs
26

27
00:02:09,400 --> 00:02:17,980
is like this for example and OR contact is in the ST language will be OR logical inclusion OR 
27

28
00:02:18,040 --> 00:02:28,570
operations M0 or M1 we will use it like this M0 or M1..and comparisons or the AND operations or
28

29
00:02:28,620 --> 00:02:37,210
equal or negative signs or reminders divisions and are etc. complete as the operators examples expressions
29

30
00:02:37,240 --> 00:02:40,700
examples and the function and symbols is in this page.
30

31
00:02:40,840 --> 00:02:47,470
You can just copy or take a photo of this page while we are writing ST  language programming or we are
31

32
00:02:47,470 --> 00:02:55,480
doing and examples about the ST programming done we will need these operators for ST  programming
32

33
00:02:55,690 --> 00:02:57,740
then I I'm going to finish this video.
33

34
00:02:58,050 --> 00:03:06,540
wE need to know these are all while we are working with a st programming so that's all.
34

35
00:03:06,610 --> 00:03:07,990
See you in the next video.
