SCADA on ARM64 and single-board computers
Raylux Nexus has been run on ARM64 single-board hardware: a Raspberry Pi Compute Module 3 on the bench, and a single-board touchscreen panel against a live PLC. It is the same gateway as on a server, with less hardware under it.
What has run
What has been run on ARM64
Raspberry Pi Compute Module 3
The arm64 package has been installed and run on a Compute Module 3 with 1 GB of RAM, running Raspberry Pi OS (64-bit). The gateway sits at about 35 MB resident when idle.
A panel in service
An ARM64 single-board panel with a 1024 × 600 touchscreen talks Modbus TCP to a PLC on the same network. Nexus holds 131 device tags, records history, evaluates alarms and serves the screens in about 38 MB of memory. It runs the ventilation of a dairy barn.
What those numbers are
Two measurements on two specific setups. They are not a sizing guide. For a larger project, the install requirements give a starting point for servers.
Getting it
Getting an ARM64 build
The ARM64 package is not among the release downloads. Ask and you will be sent a build. The architecture is in the filename, and installing the wrong one fails immediately without harm, so the package manager tells you.
After that the install matches any other Linux gateway: a systemd service under /opt/raylux with its own Python runtime and nothing to install beside it. The Install on Linux guide has the steps, and the Linux page has the rest.
The headless build has no Qt and no desktop. Studio and Lens are Windows 64-bit programs, so you design on a Windows workstation and connect to the board over the network. Operator screens are Spectrum, served to a browser. If you are planning a panel, ask us about the browser and display setup.
One thing for boards that boot from an SD card: debug logging writes a line per system tag per second, which the manual notes is real wear on an SD card. Use it temporarily and remove it when you are done.
Licensing
Panel and skid licences
Edge Panel
$995 for one touchscreen, with screens included. It allows 3 concurrent clients and keeps 45 days of history on the machine.
Edge, skid
$495 for one machine. There is no HMI: it collects data and keeps 45 days on the machine.
Both
Both run on ARM64 or x86. Building a run of machines? Talk to us. The pricing page has the rest, and compatibility lists the PLCs Raylux talks to.
Next step
Start with the trial, then ask for the board build.
Downloads are free and the trial unlocks everything for two hours, restartable as often as you like. You can try the gateway on an x86 Linux machine first.
