The Gateway Webpage performs a cadre of functions and is the hub for accessing all the functions of the Gateway server. It drives everything in Ignition! The Gateway Webpage is where you setup your licensing and activation, configure your Gateway settings, databases, devices, projects, modules, security, and alarming. When the Gateway server is running, you can connect to a device, connect to a database, launch the Designer, and launch a Vision client or Perspective session. You can also check the status of your system, network, agents, sessions, tasks, reports, and alarms.
The Gateway Webpage has three tabs on the left side of the page that lead you to the key sections of the server: Home , Status , and Config. The top of the page shows you the path of where you are on the Gateway Webpage. You can perform a host of Gateway functions from configuring your system and modules, checking the status of all your Gateway connections, to launching clients and sessions, and many tasks in between. You can even redirect the Gateway Homepage to display another URL.
The first time you go to the Gateway Homepage, it shows you several steps to help you get started. Once you're up and running, the Home tab lets you open Vision clients, Perspective sessions, and download the Designer Launcher. There are some resource links to help you get started with Ignition quickly: Inductive University, Quick Start Guide, Production Documentation where you can learn about Ignition modules, and the Appendix which contains a complete reference for components, expressions and scripting functions.
When you're first introduced to Ignition, the Homepage is the landing page. It's where you'll find the Designer Launcher, Vision Client Launcher, and Perspective Session Launcher.
The Status page provides in-depth information about the status of the different parts of the Ignition system. The list of options on the left menu in the Status page changes based on what modules are installed. You can select any of the available options to get more detailed information.
If you are not already logged into your Gateway, Config tab presents you with a login screen. Enter the username and password for the Ignition administrator. This was the first account created during installation. From the Config page, you can setup all connections, projects, and perform all the Gateway and platform operations. The list of options on the left menu changes based on what modules are installed. You can select any of the available options to get more detailed information. This page also provides some links to common actions to help get you get started.
The Designer Launcher locates all the Gateways that are available on your local network. Once the Designer is open, you can access existing projects or create new projects on the Gateway.
The Designer Launcher button on the top right side of the page and the Download button opens the Designer Launcher Download page. Here you can find all the Designer Launchers for each operating system: Windows, Mac and Linux. Ignition automatically detects your operating system so all you have to do is download the launcher and follow the steps to install the Designer Launcher. To learn about what the Designer can do, go to the Designer section of this manual.
The Gateway Command-line Utility (GCU) is a lightweight standalone application that provides information about the Gateway. It performs high-level tasks that aren't available inside the Gateway webpage such as stopping and restarting the Gateway server, and setting ports used between the Gateway and clients. It shows the status of the Tomcat web server and the Ignition Gateway application. You can reset the Gateway password, and even launch the web browser to the Gateway webpage.
For more information, refer to the page on the Gateway Command-line Utility.
The Gateway’s architecture contains many parts, each one letting you perform a specific task. The Gateway parts are as follows:
The following image shows the different parts of the Gateway and how projects work within the Gateway. Note the parts that are outside the Ignition Gateway box, non-Ignition OPC servers, databases, devices, etc., are all separate from Ignition but can be connected.
Ignition redundancy supports a 2-node system, meaning there are two copies of the Gateway running. One node is the Master Gateway and the other is the Backup Gateway or backup node. All projects, Gateway settings, etc., are shared between nodes. The master node manages the configuration then replicates it to the backup node.
When you have redundant systems in place, you can get detailed status information by going to Gateway webpage and selecting Status > Redundancy to view the system's status and events. For more about how Gateway redundancy works, go to the section on Redundancy.
