OPC Tunnel

dataFEED OPC 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, high performance, robustness and reliability for data exchange across networks are guaranteed. Thanks to the integrated Store&Forward functionality, data is buffered when the connection is interrupted and automatically forwarded after the connection is re-established.

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
