In this video, I will discuss how to assign the IP address and then how to establish
the communication between the PLC and the software. In the previous
videos, we learn about the input wiring, output wiring and the power supply
right. So accordingly, I connected all the cables with the PLC power supply
og inputs, digital inputs, digital outputs. If you see I connected the Ethernet cable also as
I don't have the Ethernet port in my laptop. I am using a Ethernet two USB converter
This is optional. If you have the Ethernet port, this is not required just directly connect the Ethernet cable with the laptop
or desktop fast. What I will do, I will connect this USB cable with my laptop
OK. So
the cable is connected and we need IP address subnet mask, gateway values
We have to enter these values in the laptop. OK. First you turn on the PLC
then we have to note down the values from there. I will turn on the power supply
So the PLC is started. So go to network menu 123
network press OK. Again you have to go to IP address. So press four we need these addresses
IP address, subnet mask gateway. We have to enter these values in the laptop
OK. So now I will go to the laptop and search for the settings
go to settings in settings, go to network and internet. Spell
it this one, right? So if you see the first one is Wi Fi for internet and the second one is Ethernet port
which I cannot tell the USB cable. If I remove the USB cable
this will be gone. I will remove it. See, there is no Ethernet port
Now I'll count the ESB cable again. The internet port is game
right? See this is the Ethernet port and go to the properties
So this is the internet. Click here. First, we have to enter the DNS server assignment
look at it. So it must be manual. Ok? And enter preferred DNS this
18.8 0.8 0.8 total four eights. Ok. And then save completed
Next, assign the IP address again. Click edit this one. He had to select manual and
enter the IP address. Ok. If you see what is the IP address on the PLC
So this is the IP address. 1 92 1 68 03, we have to enter 1 92 1 68
0. The last number we have to change. Ok. For example, the PLC is having three
You can use four here, 56, any number other than three in network
One device have one unique IP address. Ok. You cannot use the same IP for another device
So the PC is having three, you can use here 456 anything
I'm just using 10. And what is the Subnet mask? What is the value
Same? We have to enter? 2 55 2 55 2 55 0
Enter the same here Subnet must and the gateway, what is the gateway here
1 92 1 68 01 and the same address? 1 92 1 68 01
Then you click save. We already entered the preferred DNS before. Otherwise you can also enter here eucalypts
That's it. The IP assignment is completed. The only one important thing we have to remember is the IP must be
unique, either PC or laptop software. OK. There's some other number. So
the IP assignment is completed. Now open the software, go to search and search for logo
So open the logo, soft comfort V 8.4. So this is the software for programming the PLC
OK. Now go to tools and click Ethernet. It
may take some time if you are using the demo version, then this step is not required for you
There are two settings offline and online. Go to online. Enter your target IP address
the PL C IP address. What is the PL C IP address? It is 1 92 1 68 03
So enter the same IP 1 92 1 68 03. And if
you see it is a tick mark game, that means the software is connected with the PLC
You can do the programming, you can do the download or you can do the upload
The one thing you have to remember is if in case you're using an external converter
then you must select the converter option in the above. Yeah. Here you must select the respect to converter
name or option here. This is my Wi fi router and this is the sun
water. In this video, we understand how to assign the IP address and how
to establish the communication between the PLC and this software. I will meet you in the next video. Thank you
