This transport mapping implements the OPC UA Services using a SOAP request-response message pattern over an HTTPS connection. Transport security can only work for point to point communication and does not allow untrusted intermediaries or proxy servers to handle traffic. In scenarios where an intermediary is needed, the HTTPS transport cannot ensure security and the applications will have to establish a secure tunnel like a VPN before attempting any OPC UA related communication.

Usage Considerations

  • Requires significantly more resources with more overhead than UA_TCP
  • Firewall friendly: uses standard https ports.
  • XML Web Service compatible
  • Can use a browser as a Client.
