Hello.
1

2
00:00:22,020 --> 00:00:24,290
In this video we are going to learn.
2

3
00:00:24,290 --> 00:00:33,180
Station Number definition this will be very short video because this is really important point when
3

4
00:00:33,450 --> 00:00:36,490
we are trying to build a communication.
4

5
00:00:36,600 --> 00:00:45,840
We need to define our comm ports and we need to set our station numbers in special data registers.
5

6
00:00:45,840 --> 00:00:54,770
For example if we want to use Com1 RS232 communication and com2 RS485
6

7
00:00:54,780 --> 00:00:57,920
ports for plc.
7

8
00:00:57,990 --> 00:01:07,770
So for the station number we need to send our station number to d1121
8

9
00:01:07,770 --> 00:01:08,910
data register
9

10
00:01:08,940 --> 00:01:17,340
This is for the com 1 and com 2 communication and M1002 is it will.
10

11
00:01:17,340 --> 00:01:18,860
It is going to be active.
11

12
00:01:18,870 --> 00:01:28,010
Just one pulse when plc is at run situation and for the COM3 this is also RS485
12

13
00:01:28,030 --> 00:01:38,520
port communication port we need to send our station number master address to D1255
13

14
00:01:38,520 --> 00:01:41,940
data registers.
14

15
00:01:41,940 --> 00:01:51,360
These are special data registers and these are really important while we are starting to build our serial
15

16
00:01:51,360 --> 00:01:58,920
communication while we are working with the coms ,com1 , com2,com3 for the RS232
16

17
00:01:58,920 --> 00:02:06,480
and RS485 communications we need to watch out this so I am finished
17

18
00:02:06,480 --> 00:02:09,290
for this video see you in the next video.
