dataFEED OPC UA Tunnel

OPC UA Tunnel Functionality Supporting Simple and Secure OPC Classic Communication

dataFEED OPC UA Tunnel is a dataFEED OPC Suite component and avoids the occurrence of DCOM configuration problems in cross-computer OPC Classic communication. At the same time, a high level of performance, robustness, and reliability for data exchange across networks are also guaranteed. By using the security mechanisms of the OPC UA standard, such as the exchange of certificates and the use of current encryption algorithms, the OPC UA tunnel ensures maximum data security.


No need for complex DCOM settings

  • Easy industrial communication by avoiding
  • DCOM and its complex security settings on the OPC Server and OPC Client side
  • Time-saving configuration of OPC Classic communication across networks
  • Effective and efficient configuration of distributed automation systems with many OPC Classic servers

Compliance with specifications for computer, network and data security

  • Ensuring high data security for factory-level applications by using the security mechanisms of the OPC UA standard, e.g. exchange of certificates
  • Authentication via username and password including user certificates
  • Data encryption using current encryption algorithms
  • Enables secure OPC UA communication across firewalls and DMZs with OPC UA Reverse Connect

Secure cross-computer OPC Classic communication

  • Intuitive wizard-based configuration of the OPC UA tunnel connections including certificate generation and certificate exchange
  • Configuration of a secure OPC UA tunnel connection without OPC UA expertise using the practice-oriented default settings
  • Automated creation of the OPC UA Tunnel Client configuration by importing the OPC UA Tunnel Server configuration
  • Use of a common OPC namespace for access by OPC Classic clients
