This transport mapping uses the HTTPS transport for the exchange of binary OPC UA messages. HTTPS is a protocol that provides transport security. This means all bytes are secured as they are sent without considering the message boundaries. 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 more resources with more overhead than UA_TCP
  • Firewall friendly: uses standard https ports.
  • Can use a browser as a Client.
