Bridging Legacy OPC DA to OPC UA: Seamless Coexistence Without Plant Downtime

Practical engineering blueprints for deploying OPC DA-to-UA wrappers and proxies (OPC UA Wrapper, Cogent DataHub): bridging Windows XP/7 legacy control servers to modern web SCADA.

  • An OPC Wrapper sits locally on the legacy Windows machine, converting local COM calls into secure outbound OPC UA TCP packets.
  • Wrapping eliminates cross-network DCOM entirely while keeping validated legacy PLC drivers untouched.
  • Tunneling software buffers data locally when the enterprise network connection drops, preventing loss of regulatory audit logs.
