Scripting in Edge Compute
Gateway scoped scripting, such as Gateway Event Scripts and scripts that execute on a Tag (such as Tag Event Scripts or scripts called by runScript on a tag/alarm property), are unlocked when the Compute product is applied. This allows you to use any of the Gateway scoped Event scripts for your project. You will not see the “Gateway Events” menu item in the Designer on unlicensed Gateways. Applying a compute license will require a Designer restart before the menu item will appear.
Edge Gateway Network Messaging
Edge Compute provides access to call message handlers on other Gateways. This allows you to send data to other Gateways to be dealt with. You can access this functionality through the following system.util messaging functions:
Edge Compute comes with the WebDev module, which enables you to directly program against the web server inside the Ignition Edge Gateway and systems running Vision Clients. This gives you the ability to host web pages or files, and create full-fledged REST APIs that allow external systems to interact with the Ignition server.
