A layer 3 network switch operates at the Network Layer of the OSI model. Read more information about the OSI Model. Layer 3 network switches forward data based on IP addresses. Unlike layer 2 network switches, layer 3 switches route traffic between different subnets. These switches combine the features of a traditional router and a…
The Open Systems Interconnection (OSI) model is a reference model which describes seven layers of communication between computing systems over a network. These seven layers are as outlined: The OSI model was developed by the International Organization for Standardization. It describes the tasks required to transmit data via radio waves, light, or electricity.
A network switch is a networking appliance that connects multiple devices inside of a Local Area Network (LAN). It communicates by forwarding data based off MAC addresses. Typically switches operate at layer 2, data link layer, of the OSI model. However, they can operate at layer 3, network layer, which communicates by forwarding data based…
MapleLogic has the ability to run a project file in simulation mode for testing purposes. Simulation mode uses the computers loopback address. The loop back address connects to the local computer and simulates PLC operations.
In MapleLogic, registers store data used for control logic and operations. They hold values such as integers or bits. Registers are essential for monitoring inputs, and controlling outputs. Common register types include discrete, word, timer, counter, and floating-point.
MapleLogic utilizes logical control operations in a ladder diagram called a “rung”. Each rung contains inputs and outputs. Inputs are usually sensors, switches, or conditions that control output devices. Rungs evaluate from left to right activating outputs based off condition parameters.
The string table in EasyBuilder Pro is a centralized database for managing multilingual text used in HMI projects. By pre-configuring texts and their corresponding numbers in the string table, text can be changed dynamically on the HMI. This feature simplifies creating multilingual interfaces by linking text objects directly to the string table. String tables are…
The Label Tag Library in EasyBuilder Pro enables the creation of a multi-language environment for HMI projects. Users can create a Label Tag Library and select suitable labels for use throughout the project. At runtime, the project dynamically displays the corresponding language based on predefined settings. This feature supports up to 24 languages simultaneously, making…
A register address in EasyBuilder Pro refers to a specific memory location used to store and manage data within a system. A register is a specific storage location, typically in memory or a device, used to hold data for processing. They often are categorized as internal or external registers. An address is a unique identifier…
XML stands for Extensible Markup Language and its a way to store information in a tree structure with tags and elements. XML Data is stored inside tags, and each tag can have attributes or nested tags that contain values. For example our OPC UA Client XML file structure has a main tag of UaClientConfig. UaClientConfig…
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…
In EasyBuilder Pro, a WORD refers to the size of the data type configured for the system. This is the standard size used to store data in registers and memory locations within the system. Our LW, PLW, RW, RW_A, EM0-15, RECIPE, RWI, PRW registers store WORDs into addresses. Naming rules for variables inside the Macro…
