dataFEED OPC Tunnel

OPC Tunnel Functionality Supporting Simple and Secure OPC Classic Communication

The dataFEED OPC Tunnel is a component of the dataFEED OPC Suite and eliminates DCOM configuration problems that can arise in OPC Classic communication between different computer platforms. At the same time, it ensures a robust and reliable high-performance data exchange also across network boundaries.


No Need for DCOM Configuration

  • Easy industrial communication by avoiding DCOM and its complex security settings on the OPC Server and OPC Clientside
  • Time-saving configuration of OPC Classic communication across networks

Compliance with Computer and Network Security Policies

  • Secure communication across firewalls
  • Minimum requirements on configuration of PCs used in network
  • Compliance with corporate security policies for firewalls

Data Buffering on Detection of Broken Connection

  • Protection against data loss by automatic local data buffering on detection of broken connection to OPC Client
  • Second-by-second monitoring of OPC Classic communication
  • Automatic re-establishment of OPC connection and transmission of locally buffered OPC data
  • Improved OPC communication behavior
