How to Setup Ethernet/IP Comm to Receive 2D Matrix Code Between Omron V430 Using Omron Weblink

Hello everyone, today I'm going to show you how to set up an Omron V430 bar code Reader to read a 2D matrix code and send it out to PLC via Ethernet IP.

I am Tom Trinh, Senior Application Engineer for Valin Corporation. Let's get started.

So, what do you want to do first is to open your browser and type in the IP address of the V430 bar code reader. In my case, it is going to be and what it will do is that it is going to launch the Omron WEBLINK inside the code reader and allow you to set up. So here we are. So first you want to set up the trigger. Change that to continuous so you can see how the image looked like. Then so it looks good. It's in the field of view you want to put it back in the trigger mode. And then what you want to do next is to set up your windows of interest where you want the code to be read. So, this region right here you can move them around you can size them. And then what you want to do next is select this icon which is quick photometry and what it would do is that it is going to basically automatically set up your exposure time. And when it finished you will see it down here. OK, so it's done and then what you want to do next is to select this autofocus.

So, I'm going to select this and place it right on the code itself. So, what it will do is automatically is to adjust your focus and make sure it's set up correctly. So right here it showed 287 mm. And that means it's how far it is away from the code to the tip of the lens of the V430. What you want to do next is to select this icon here to train symbol setting and set up the best read performance. So this is going to take a while. The nice thing about this is that it does everything for you. It selects the code. It's optimized and give you the best performance to read the code. So, it's going to take a while, it is 67% done. I'll show you later on so if you want to go in and change some of the exposure time or gain and how to get little bit more performance out of it. You can do that. So, it looks like it read it. I'm going to try at different location here. When I rotate it a little, that's ok. Alright, I have another code on this side. It reads OK as well. I'm going back.

So, as I mentioned before, if you want to go in and change the exposure time, you can do it here. You can change the gain. You can do that as well, so let me make it darker little bit alright. And I'm going trigger it. You see, it is still reading it even at that dark. But let me bring it back up a little bit. Also, there's a feature on here that you can set up so if it's matching the string that you taught, then it will give you an output. And if it doesn’t match then it will give you an output as well, a different output. So, I'm going to switch it over here. I'm going to trigger it. OK, and you will see it shows mismatch here. OK I'm going to put it back. Trigger it again and it is matched. Now, you can set up the string however you want it to be sent out. You can set a preamble string if you want to. For me, I'm just going to leave the code the way it is and then have the carriage return linefeed when it sent it out. As far as the output, you got three output to set up here if you want to. 1st One is match, so it's matching the code, then that output will turn on. If it does not match, then the upper two would turn on. 3rd one, it is a mismatch or no read. OK, so you got three output to play with.

Now if you want to change that you can click on it and you can select this and select the arrow down and select different option here. OK but for now I'm just going to leave the way it is. I click done here. The next thing I want to do is to set up my Ethernet IP so it can send out a string correctly. So to do that, you select this gear icon and select Advance. Once you are here, you want to select communication tab and under this tab, there's a Ethernet IP. Make sure that is enabled. Also, in here there's a Ethernet IP byte swapping. The nice thing about this is in certain PLC, you may need to enable this, and it will do automatically swap the byte for you. Otherwise, you have to do that in the PLC, which is more code for you. But this automatically takes care of that. For me, I'm going to leave it the same. I’m going to close it. And so that's it. That's how you set up the V430 to read the code and send out the string via Ethernet IP to the PLC. If you have any questions, please call  (855) 737-4716 or fill out our online form.
