Hello. 1
In this section we are going to learn COMMGR software and how to build communication between 2
our PC and PLC. So we installed commgr software to computer and now we 3
need to create our drivers. 4
Open your commgr software and come here. 5
Click Add button and in here. 6
Driver properties section is going to open. 7
So now let's give to your driver name for example. 8
This is rs2 or let's say serial communication driver and how we are going to connect to our plc 9
we can select RS232/422/485 10
Communication USP virtual communication or internet or direct link or direct link USP or Internet TCP 11
simulator.so we will create also simulator in the next lessons. 12
But now we will connect to real PLC via RS232. 13
This is my selection and for the comport you need to connect your cable to your PC. and directly communication 14
inside of the communication protocol comport will be detected and I will say now auto detect now it 15
is asking to us what is the node id or what is your plc id. 16
And it is zero and I will say okay. 17
And it is detected. 18
So my plc settings are data length is 7. 19
Parity is even stop bits one and baudrate 20
9600. 21
This is all communication settings and it is because of the auto detect button and with help of auto 22
detect button it is detected and I will say OK so now you see it is started not stopped and in here 23
I will go online to my PLC I will say go online and program is going to be compiled. 24
This is a empty project and now in valid driver or commgr are not startup. 25
This is an error why because we need to select our communication settings in tools area. 26
Come here. 27
Select your driver. 28
This is another one important point. 29
As you can see a little bit ago if you say okay directly go online it will give this error to you. 30
So inside of the project you need to select your driver and I will say okay this was my driver and you 31
can see in here. 32
Serial communication we created and I will say okay. 33
And again let's try once go online to PLC and okay. 34
Sent this project, empty project to PLC and say yes. 35
Now this empty project is transferring to your PLC and yes. 36
And okay. 37
And also PLC is run situation and now we connected to existing in real PLC. 38
And now we sended our project to PLC. 39
So let's go off line now we are off line from our plc. 40
So I'm finished for this video. 41
See you in the next video.
