A virtual local area network (VLAN) segments a physical network into smaller, isolated networks. It can help improve security and performance on a network. Layer 2 switches may create and segment VLANs but cannot route traffic between them, unless it has VLAN routing, or router-on-a-stick capabilities. Layer 3 switches or routers perform routing between VLANs,…
HTML5 is the latest version of HTML (Hypertext Markup Language). It is used to build websites and web applications. HTML5 makes it easier to create interactive, and responsive web pages that work across different devices and browsers. HMIs and PLCs may interact with HTML5 web servers through network communication protocols such as HTTP/HTTPS. These devices…
A UDP port is a communication endpoint for transmitting data between devices on a network using the UDP protocol. On Maple Systems products, UDP ports enable fast, connectionless communication for applications like broadcast messaging or time-sensitive data transfers. Each port is identified by a unique number, ensuring multiple applications can operate without interference. Commonly used…
A TCP port is a communication endpoint for transmitting data between devices on a network using the TCP protocol. On Maple Systems products, TCP ports facilitate connections between HMIs, PLCs, and other networked devices for data exchange and control. Each port is identified by a unique number, allowing multiple applications to run simultaneously on the…
