The Gateway Control Utility (GCU) is was a lightweight standalone application which provides information about the Gateway. It also provides some basic functionality such as starting and stopping the Gateway, opening the Gateway webpage, performing a Gateway Backup and Restore, resetting the Gateway password, and more.
Older versions of Ignition featured a visual Gateway Control Utility or GCU that could start and stop the Ignition service. This visual element of the GCU, as well as the ability to start and stop the service have since been removed in Igntion 8.0. For more information on starting or stopping the service, please see the Gateway Settings page.
More information on the older version of the GCU can be found in Deprecated Features of the user manual.
The Gateway Webpage (or Gateway Web Interface) is a series of pages hosted on Ignition's web server, and is the hub for accessing all functions of the Gateway server. It is where you setup licensing, Gateway configuration settings, database connection, devices connections, modules, projects, security, and more. When the Gateway server is running, you can connect to a device, connect to a database, launch the Designer, and launch a client. You can also check the status of your local Ignition system, agents, sessions, tasks, reports, alarms, and more.
