OPC DA → OPC UA Gateway

Any industrial data source,
one standard OPC UA feed.

SyncNode Gateway bridges legacy and vendor-locked industrial protocols — Siemens WinCC, Honeywell QCS, Beckhoff, OMRON and Siemens PLCs — to OPC UA, the open standard every modern SCADA and historian already reads. Installs in minutes. Configured from a browser. No programming.

What it connects

Four ways in. One way out.

Everything the gateway reads is republished as a single OPC UA server that any standard client — Ignition, WinCC, AVEVA, a historian, an MES — can subscribe to.

OPC DA
Siemens WinCC, Honeywell Experion / QCS RAE, Beckhoff TwinCAT, Kepware, Matrikon — any OPC DA server, over 32-bit COM/DCOM. The gateway tries the correct Automation wrapper chain automatically. OPCServer.WinCC.1
OMRON FINS
CJ2-series PLCs over FINS/UDP. Node number read from the last octet of the IP; DM, CIO, WR, HR, AR, TIM and EM areas.
Siemens S7
S7-300 / 400 / 1200 / 1500 over Snap7, PUT/GET on non-optimized data blocks.
Cross-Bridge
Copies values directly between two PLCs (OMRON ↔ Siemens) with no extra ladder logic — with an optional watchdog heartbeat so the destination knows when the data goes stale.

Why it exists

The hard part is getting data out of OPC DA.

Pulling tags from a WinCC, Honeywell QCS or TwinCAT server is notoriously fiddly: it depends on 32-bit COM/DCOM, the right Automation wrapper, and DCOM permissions that take an afternoon to get right — and it fails with class-not-registered errors that name nothing useful.

SyncNode Gateway carries that knowledge inside the product. It ships its own 32-bit runtime, picks the wrapper that actually works, and when a source will not connect it tells you, in plain language, exactly what to fix.

The customer installs nothing else. No Python, no OPC toolkit, no development environment.

01Automation wrapper chain. Matrikon, Graybox, HSC, RSI or the stock wrapper — tried in order, so a Honeywell RAE server one refuses is browsed by another.
0232-bit by necessity. The OPC DA Automation wrapper is an in-process 32-bit COM server; the gateway runs a private 32-bit process so it always loads.
03Named failures. A busy port names the process holding it; a dead source explains whether it is unregistered, 64-bit-only, or gone.
04On-site self-check. A one-press verifier confirms data is actually leaving the machine on the OPC UA endpoint.

The licences

Buy only the sources you bridge.

Each source is a separate licence — perpetual, node-locked to one machine, and activated offline. Activation is additive: buy a second source later and it adds on without touching the first. Prices in USD.

OPC DA Server 1 → OPC UA

opcda
$1,000perpetual / machine

Bridges one OPC DA (COM/DCOM) server to OPC UA. This is the flagship: the hard, valuable part of the product, and what most sites buy first.

Connects Siemens WinCC, Honeywell Experion / QCS RAE, Beckhoff TwinCAT, Kepware, Matrikon — any OPC DA server.
Best for a plant whose SCADA or historian cannot read a legacy or vendor OPC DA server directly.
Runs as its own private 32-bit process; publishes on opc.tcp://…:49321.
Trial Evaluation key (7 days) or purchase — protected by the licence vault.

OPC DA Server 2 → OPC UA

opcda2
$1,000perpetual / machine

A second, fully independent OPC DA source on the same machine — its own process and its own OPC UA port — so one failing source never affects the other.

Connects a second OPC DA server, e.g. Honeywell QCS alongside a Siemens WinCC on Server 1.
Best for a station that must bridge two different OPC DA servers at once.
Runs as a separate 32-bit process on a separate control port; publishes on its own OPC UA port.
Trial Evaluation key (7 days) or purchase

OMRON FINS (CJ2) → OPC UA

fins
$300perpetual / machine

Polls OMRON CJ2-series PLCs over FINS/UDP and publishes their memory to OPC UA — no OPC DA server involved.

Connects OMRON CJ2M / CJ2H over FINS/UDP (port 9600). Node number from the last IP octet.
Memory areas DM, CIO, WR, HR, AR, TIM, EM0–EMC.
Best for OMRON lines that need a clean OPC UA feed without extra hardware.
Trial Free 7-day trial — install and run.

Siemens S7 → OPC UA

s7
$300perpetual / machine

Reads Siemens S7 PLCs over the Snap7 protocol and publishes to OPC UA — direct to the PLC, no WinCC required.

Connects S7-300 / 400 / 1200 / 1500 over TCP port 102 (PUT/GET, non-optimized DBs).
Set-up enable PUT/GET and un-tick "optimized block access" on the data blocks.
Best for Siemens lines that need OPC UA straight from the controller.
Trial Free 7-day trial — install and run.

Cross-Bridge Routing

bridge
$300perpetual / machine

Copies values directly between two PLCs (OMRON ↔ Siemens) with no extra ladder logic — a data mover, not a UA source.

Does register-to-register transfer between an OMRON CJ2 and a Siemens S7.
Watchdog an optional heartbeat counter lets the destination ladder detect stale bridged data.
Best for integrating two PLC brands without reprogramming either.
Trial Free 7-day trial — install and run.

Before you buy

Try it on your own station.

Free 7-day trial

OMRON FINS, Siemens S7, Cross-Bridge. Install and run them for 7 days with nothing to activate — no key, no internet. After day 7 the source stops until a licence is activated; anything you configured is kept.

Evaluation key

OPC DA Server 1 & 2. The OPC DA engine is protected by a licence vault, so it needs a signed key even to evaluate. Send us your Machine ID and we issue a 7-day evaluation key for that machine, free — the same one-line activation as a purchase.

Every licence is node-locked to one machine via its Machine ID (SNG-XXXX-XXXX-XXXX-XXXX), activated offline, and perpetual unless you agree a time-limited key. Nothing phones home.

Pay with PayPal E-mail my order & Machine ID

Payment is handled by PayPal — you pay SyncNode Works (herrviko@gmail.com); we never see your card. Choose at least one licence to enable the buttons. After payment we issue your key to the Machine ID you gave and e-mail it back — usually the same business day. Prefer to pay another way (bank transfer, invoice)? Use E-mail my order and we will arrange it.

  • Optional install as a Windows service for permanent plant use.
  • A built-in System Check that diagnoses the install on the spot.

System requirements

  • Windows 10 / 11 or Windows Server, 64-bit.
