Install, commission and operate Nexus — the tag engine, historian, drivers, alarms and web server that the rest of Raylux connects to.
This manual covers Raylux Nexus, the Nexus service, and the two client programs that connect to it:
| Component | What it is | Who runs it |
|---|---|---|
| Raylux Nexus | Nexus — tag engine, historian, device drivers, alarms, reporting, and the web server that serves everything else. Runs as a Windows service or a systemd unit. | Installed once per site, on a server. |
| Raylux Studio | The designer. Builds the screens, tags, alarms and reports that Nexus runs. | On an engineer's workstation. |
| Raylux Spectrum | The operator runtime, served by Nexus as a web page. Nothing to install — it is a browser. | Any machine on the plant network. |
| Raylux Lens | A desktop shell that displays Spectrum full-screen, for a panel PC with no desktop. | On plant-floor panels. |
You are reading this from Nexus itself, at /manual. It is installed alongside Nexus and works with no internet connection.
Version
This manual is built and shipped with Nexus, so it always describes the version you have installed. Check the version on Nexus's Overview page, or run raylux-nexus --version.
