Securely network OPC servers and clients without the headaches of DCOM

The DataHub® DA Tunneller provides the easiest and most reliable way to securely communicate between networked computers. No DCOM, no configuration issues, and no time-outs. It does away with the headaches typically associated with DCOM configuration.

While DCOM requires a reliable communication network, DA Tunneller operates well under sub-standard networking conditions, widely distributed network nodes, and unreliable infrastructures such as satellite or wireless networks. DA Tunneller never drops the OPC server or client connection, even during network breaks.

The Cogent DataHub DA Tunneller:

  • Private-cloud ready
  • Easy to configure
  • Eliminates DCOM configuration hassles
  • Provides seamless real-time OPC data transfer across geographical locations
  • Shields OPC servers and clients from network breaks, and minimizes timeouts
  • Communicates with multiple OPC servers and clients
  • Provides data encryption for security
  • Provides real-time connection and tag status
  • Includes full featured diagnostic tools
  • Use our built-in scripting tools to customize your installation and monitoring needs

What our customers are saying:

“We had OPC servers on our equipment, but found that using DCOM for networking was too risky. It required us to open too many ports in our firewalls. We had to find a way to avoid using DCOM…For us, this OPC tunnel is very good, because we only need to open one port, and we are secure from DCOM break-ins”

– Mr. Michele Mannucci, ABB Project Engineer


As with most of our license packs, the Cogent DataHub® is also fully integrated with Skkynet’s SkkyHub™ service; an end-to-end solution that makes it easy to connect and network any number of industrial systems or data sources.

You can visualize real-time data with our built-in Web-based HMI – or your own, monitor or control your process or equipment from almost anywhere, and network any plant or remote system, with no additional hardware or programming necessary.

No open firewall ports, no VPNs to manage; secured by design.
