VLAN stands for Virtual Local Area Network. So, what does the “virtual” adjective mean? In a nutshell, VLANs allow a group of Ethernet devices (subnet) to be physically separated by many Ethernet switches but communicate as if they were all connected to the same physical Ethernet switch.
One of the questions I get asked often relates to what network communication options are available with the myriad of automation controllers available today. The use of these communication options varies as much as the different protocols that have been created over the years.
So, what is Ethernet/IP protocol? Think of the network as a transport mechanism, be it a phone line, serial twisted pair, Ethernet, or some other physical layer and the protocol as the language used on that network. This post takes you through the basics of Ethernet/IP.
Any project that requires standardization, normalization, and integration will have challenges. A robust modern network increases visibility, minimizes risk, and helps achieve overall profitability. If you are thinking about converging Ethernet networks, you may be looking for support.
