Start, operate, ask

Start.

All eight protocols are in the box, none sold separately. Install Nexus once per site and the plant is online.

Where it runs →

Operate.

The same screens on a desk, a panel and a phone. Served by Nexus, so there is nothing to install on the machine that shows them.

Meet Spectrum →

Ask.

Iris lets the AI assistant you already use read your plant and explain an alarm in plain English.

New in 2026.20 · Raylux Iris

Ask your plant what’s wrong.

Iris lets the AI assistant you already use look at your plant through Nexus (live tags, alarms, history, devices and projects) and explain in plain English what it thinks is going on, and why.

  • Read-only. Iris reads; it never writes to the plant.
  • Scoped. Each key acts with a role you choose, checked on every call.
  • Audited. Every call lands in the Nexus audit log under its key.
  • Open. Built-in MCP server, so any MCP client can connect.
Film An EQ tank alarm, asked about in plain English. The tool calls and readings are real, from a running Nexus on a simulated demo plant; the answer is the assistant’s reply, set out as cause, evidence and first check. Watch the full film, with sound.
