  1. Often with new In-Sight Vision Systems or Vision Sensors, or ones that have been on the shop floor for a while, you find that you can't connect to the system. You may forget what the IP Address is of the camera, or if it's new it comes set to DHCP and you can't get connected. The steps below will help you get connected. We recommend in order to simplify the setup, use hard-wired Ethernet from your PC to a simple Ethernet Switch and nothing else. The reason for this is to make sure that we don't have any address conflicts and that simple communications can work. Do not use a router, or a managed switch, just a simple unmanaged switch. Typically we could also go directly from the PC to the camera without the switch, but some older PCs do not have auto-crossover hardware whereas most switches these days do allow for this. Step 1: Connect your PC and camera to a stand alone network switch, use the wired network port of your PC. Step 2: Set a Static IP Address for the PC's Ethernet Port This depends greatly on your operating system how you get to the list of network adapters. But in the end we typically want to get to "Network Connections" In most Windows operating systems once you get to Control Panel, go to Network and Sharing Center, then "Change adapter Settings", you should see a screen something like this with your various network adapters. Right Click on Ethernet (or whatever your wired network adapter is) and select Properties. Next select the IPV4 line and click Properties again. Set the IP address to a static address. Most companies will use 192.168.0.X or 192.168.1.X for their company network, some will use the 172.16.X.X range and some will use the 10.X.X.X range. We just want to pick something that does not conflict with your company network. Often a 192.168.3.X address will work, so for our example we will use 192.168.3.100 So your settings will look like this: After you click OK, you will now have a static IP Address on your PC. Step 3: Open In-Sight Explorer Step 4: Click on Get Connected Step 5: If you see the camera in the list, you can select it and click Connect, but most likely it will not be there, so you will need to click Add Step 6: Decide if you want to change the Camera's IP Address or your PC, and set the appropriate device's IP Address. The Camera will show up in the list, if you select it you will see it's IP Address. If the camera is part of a working machine, you want to change your PC's IP address to be in the same range as the camera, so go back to Step 2. If the camera is new or not part of a working machine, then it's okay to change it's address as shown below. Step 7: Go back to Get Connected and select the camera and connect!
  2. Maybe you are new to Ethernet Networking or maybe you’ve been doing it for a while and you know how to get it to work but fumble most of the time before getting it right. Either way, this blog is intended to give a basic understanding of Ethernet networking. We won’t get into more advanced topics like VLANs and DMZ, and if you haven’t even heard those terms, that’s fine. This is meant as a beginners guide. So let’s get to it. Firstly, let’s talk about your address. No, I don’t mean your city and state or even your country. But instead your IP ADDRESS! IP is just the abbreviation for Internet Protocol. Your IP Address is where your PC lives on the network. It’s as simple as that. What’s more complicated is that there are different networks. For people new to networking, we think that everything these days is internet connected, but that’s just not true, and honestly we probably don’t want everything directly connected to the Internet, that would make things more vulnerable than they need to be. But for now let’s start with your company’s network and the internet so we can explain what happens on that type of network. Let’s pretend instead of your PC being a computer, let’s imagine that you are a student starting mid-semester at a new school. When you arrive at school on your first day, you wouldn’t just walk in and sit down at any desk. You are aware that people probably have assigned seats so you would ask the teacher where you could sit right? Well your PC does the same thing on a company network. When it arrives it asks for a “seat” from the teacher. In this case the seat is an IP address and the teacher is a device on the network called the DHCP Server. When you connect your PC to a network via WiFi or a company wired network, you are almost always using DHCP (Dynamic Host Control Protocol) to be provided an IP Address so that you don’t conflict with other computers on the network. Okay, great. So you have an address, you know where you are. But – do you know how to get a message to someone else? If they are in your classroom with you (to extend the metaphor), you don’t need any help getting them the message. You just talk to them directly. This is because they are part of your SUBNET. Because of what’s called the Subnet Mask, our PC can know who it can talk to without any help. We can communicate with all of the PCs and devices that are on our same Subnet. But if someone is outside of our subnet we need help passing the message along. The device which passes the message along is called the Gateway. A common IP address used on home networks and sometimes small networks will be something that looks like 192.168.0.X where X changes for each device. The typical subnet mask used along with this IP address is 255.255.255.0. To keep this simple, just understand that the 4 numbers of the IP address mate up with the 4 numbers in the subnet mask. So: - 192 mates with the first 255 - 168 mates with the second 255 - 0 mates with the third 255 - X mates with the 0 at the end And at the simplest level. If you see 255, this tells you that the numbers MUST match for communication to work without needing someone to help. So if both devices have a subnet of 255.255.255.0 then all 3 first numbers in their IP addresses must be the same or the two devices won’t talk to each other without someone helping. You can think of it kind of like this, an IP Address has four parts: Town.School.Classroom.Seat As far as Subnet mask is concerned, if the Subnet Mask says 255=the number must match, 0=doesn’t matter for communication. There’s a lot more to this, but we are trying to keep this simple. Therefore if we had subnet of 255.255.255.0 it indicates that Towns must match, Schools must match and Classroom must match. Then for example 192.168.0.100 can talk to 192.168.0.22. But 192.168.0.100 can’t talk to 192.168.1.22 because their third octet (classroom) doesn’t match. You can find a much more detailed description here of how this works if you’d like to read it. https://docs.microsoft.com/en-us/troubleshoot/windows-client/networking/tcpip-addressing-and-subnetting Great, so we are starting to understand the terms. IP address is our specific location, subnet mask is who we can talk to without help, and Gateway is the helper to talk to people outside our classroom. What about if we know someone’s name, but not their address? How do we talk to them? That’s where DNS servers come into play. Think of the DNS server like a phone book. If you know someone’s name you can look up their number. When you connect to a company network, typically the “Obtain an IP Address automatically” box is checked. Then the DHCP server will give you ALL of the information on this page. It will give you an IP Address, an appropriate subnet mask, the address of the Gateway and a couple of possible DNS servers to use, so when you want to get to http://www.gibsonengineering.com you can find out the address. And when you want to send information to Gibson Engineering, you will give that information to the Gateway device and it will pass it along for you. So overall things kind of look like this, where the Gateway is allowing the connection to the internet – in this picture imagine the cloud as the internet. Okay, so that takes care of the company network and getting internet access. But what about my industrial network? Well here’s the trick - we want to keep them separate! If my company network has 172.16.20.X addressing then we can use 192.168.0.X addressing. But if it uses 192.168.X.X already, then I want to pick something different. Why? Because we don’t want confusion. Remember my analogy of Town.School.Classroom.Seat? Well in the USA there are 88 towns named Washington. There are 399 instances of schools named Lincoln in the USA. Even if we have two separate network cards in the PC we are using, if the towns and schools are the same, how does the software I’m using know where to send the message? Having two network cards in a PC actually allows me to communicate on two separate networks simultaneously, but if they are both using the same addressing scheme then it still won’t work. However, subnetting will often allow things to be very close and not cause conflicts. For instance, my company network could be using 192.168.0.X addresses with a subnet of 255.255.255.0 but if I wanted to, I could set up all my PLCs and HMIs and barcode readers and cameras and other industrial devices on 192.168.1.X addresses and if my subnet for that card is 255.255.255.0 then there are no conflicts. This is why Mitsubishi choses to default to 192.168.3.X IP Addresses for their devices because they know that most likely this won’t interfere with most company networks by default. So in the end, I’m often setting up my computer to look something like this: To summarize, we usually have two separate networks in Industrial Automation. Our machine network and our company network. They must have two different numbering schemes to prevent conflicting addresses, and the IP addresses and subnet masks must match for things to be able to communicate. Quick checklist for troubleshooting connection problems: 1) Do you know the IP address of the device you want to talk to? i.e. 192.168.3.18 2) Is your IP address in the same range? i.e. 192.168.3.X anything other than 18 3) Do your subnet masks match? 4) Is your IP address unique? Is something trying to use the same address? If all of the above looks correct, it’s often a cabling problem or a conflict with some other software such as Firewalls or Antivirus software preventing the software from talking. As networks get more complicated and security becomes a bigger concern, there will always be things not covered by this article. But with a good general understanding of how networks work, you can usually solve most networking issues.
  3. Typically when setting up most industrial devices for the first time on your network, you need to configure your PC for a Static IP Address. There are many websites out there that can walk you through this, but this one from Microsoft should be kept current. You can select your OS from the top and get specific instructions: https://support.microsoft.com/en-us/help/15089/windows-change-tcp-ip-settings This will cover Windows 7, 8 and 10. Make sure to expand the section on specifying the IPv4 settings manually for Windows 10. There are also a lot of good resources out there from other sites, but they may not be as stable or current as the Microsoft link above. Here's one I have used which has good pictures to follow along with: https://www.howtogeek.com/howto/19249/how-to-assign-a-static-ip-address-in-xp-vista-or-windows-7/
