OPC UA export — common questions

Yes. Drop a NodeSet2 XML file onto the app and OPCUAexport resolves all node references, merges CODESYS struct members, and writes the CSV entirely offline — useful on air-gapped networks or before commissioning has started.

The CSV includes all the fields a SCADA tag import needs — address in NS1|String|/codesys/volatile/… format, data type, engineering units, and ranges. Most systems import it directly or with minor column adjustments for your specific version. Need help mapping it to your system? support@opcuaexport.com →

Correct. OPCUAexport ships as a single .exe with no installer, no runtime dependency, and no Windows service. Copy it to any folder you have write access to and run it directly. No registry changes, no elevation prompt.

The free (unlicensed) version exports up to 150 variable nodes per CSV. Browsing and filtering are unlimited. A full license is free to request until 2026-12-31 — see the License page for the activation key. From 2027: paid tiers from €99/year — see the License page for details.

Version 1.0 supports anonymous authentication only. Connect to any server that accepts anonymous connections. Future versions will add username/password and certificate-based authentication.

No. OPCUAexport has zero telemetry, no auto-update calls, and no network access beyond the OPC UA server you explicitly point it at. It is a free SCADA tag exporter that runs fully offline.

Yes. OPCUAexport exports all core tag fields — name, OPC UA address, datatype, engineering units, and ranges — in a semicolon-delimited CSV. Ignition’s tag import accepts CSV with column mapping, and the core fields align with Ignition’s tag structure. Ignition JSON export is on the roadmap for direct import without manual column mapping. support@opcuaexport.com →

OPCUAexport produces a structured CSV with tag name, OPC UA address, datatype, engineering units, and ranges — the core fields all three systems accept for tag import. Minor column mapping is typically needed for your specific version. support@opcuaexport.com →
