Getting help with Voltrus SCADA

Frequently Asked Questions

I can't connect to my Modbus TCP device.

Verify the device IP address and port (default Modbus TCP port is 502) are correct in your config. Ensure your SCADA server can reach the device: try telnet <device-ip> 502 from the server. Check that the device's unit ID matches your configuration. For firewalls, ensure the port is open on the device.

How do I activate my license?

Core needs no licence. For an Integrator or Enterprise licence, set the VOLTRUS_SCADA_LICENSE environment variable to the key you received from Polar.sh, then start the binary. The key validates on startup. After the first validation, the binary works fully offline.

I have an old Edge, Starter, Professional or Enterprise license. What happens?

It keeps working. Edge and Starter become Core, so nothing is lost. Professional maps to Integrator. Enterprise stays Enterprise. To move up, contact us with your license key. Your existing deployment keeps running: no reinstallation needed.

Are there device limits?

No. Core has no device, tag or retention limits. The old Engineering mode and per-tier device caps have been removed.

How do I run SCADA on a $4 VPS?

The SCADA process used about 30 MB of RAM after start in our btop capture on a small VPS, and the binary runs on x86_64 Linux. Download the binary, copy your config YAML, set your license key as an environment variable, and run with ./voltrus-scada. Your dashboard is live on port 3000.

Does it require internet access?

No. Core never phones home and runs fully offline, and your industrial data never leaves your network. A paid licence is activated with a signed file, so it works offline too. Online installs can refresh a monthly licence from the activation server.

How do I set up SSO or authentication?

Core includes local authentication with Argon2 password hashing and role-based access control. An Enterprise licence adds SSO with Active Directory (LDAP over TLS), Azure AD (Entra ID), Okta, and any SAML 2.0 or OIDC provider.

Can I white-label it for my clients?

Yes, with a paid licence. The dashboard supports custom title, subtitle, and logo through the UI config. Your clients see your brand, not ours. White-label and the full theme editor need an Integrator or Enterprise licence.

The binary crashes on startup.

Make sure your server has a compatible kernel (Linux 5.10+ or Windows Server 2019+). Check that the binary is executable (chmod +x voltrus-scada). Verify your config YAML is valid: run ./voltrus-scada --check-config to validate. If the issue persists, contact support with your OS, architecture, and error output.
