DataHub Tunneling - Secure OPC Data Transmission, Remote Data Access

Tunnel More Than Just OPC, Securely and Robustly

DataHub is about more than just OPC and the tunneling capability. Although we show OPC tunneling here, any data points you can get into DataHub's unified dataset can be tunneled as the examples on this page will show.

• Up and running in a few minutes 
• Mirrored data results in faster data transfer, instead of just tunneling OPC commands like other tunnelers.
• Configurable network break detection heartbeat as fast as 50 ms and automatic recovery
• Integrated quality indicators to tell clients when the network is down
• Encrypted and password protected data transfers 
• Tunnel endpoints configurable as read-only or read-write
• Define specific security level required for a connection to succeed on each endpoint
• User configurable TCP/IP Port
• Single or Bi-Directional transfers
• Proxy and DMZ friendly
• Aggregate multiple data sources and destinations 

OPC UA and DA Tunneling

• Access remote data without exposing your plant network
• Aggregate data from different OPC standards from multiple remote locations
• Integrate OT and IT through proxy and DMZ friendly connections
• Securely move OPC DA data between machines, differing Windows versions, domains, and networks without using DCOM
• Detect network breaks quickly, recover smoothly without user intervention
• Tunnel value, quality & timestamp by default, with definable changes to quality based on connection status
• Engineering Units & Ranges included if provided by the OPC sources (V10+)

This feature set is licensed through the DataHub Tunnel Pack which comes in an OPC DA and OPC DA+UA version. 

Historical Data Tunneling

With DataHub V10 and newer, several scenarios are possible for securely handling historical data, including sourcing remote data to be stored, tunneling it, and securely delivering it to any supported historian for logging.  When using InfluxDB as the historian, secure historical data tunneling with store and forward can be achieved through the unique capabilities of DataHub with Influx DB.  Proper tunneling of historical data has to consider many factors to do it well, and we encourage you to talk with us about your use case. 

DDE Data Tunneling

DDE may be a legacy technology but there are still many applications out there that use it, and with DataHub's DDE client capability, you are able to tunnel that data securely with the same robust capabilities as tunneling OPC data.  Combine the DataHub DDE feature with an OPC tunneler solution pack or other features to integrate DDE into your modern OPC UA and IoT architectures.
