DataHub Tunneling - Secure Data Transmission, Remote Data Access

Tunnel More Than Just OPC data, 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 
• Exception based data changes 
• Mirrored data results in faster data transfer, instead of just tunneling OPC commands like other tunnelers.
• Single or Bi-Directional transfers
  
• Data Diode Mode provides enhanced single direction tunnel security + support for hardware data diodes
• Separate reads and writes on different tunnels for more security 
• 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 (SSL/TLS to highest level on users machine) 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
• Proxy and DMZ friendly
• Aggregate multiple data sources and destinations 

Video Tutorial Training

In this video training, we connect an OPC client and server over a network, between Windows Server 2008 R2 and Server 2019 machines that are not in the same domain. For users trying this with DCOM and without tunneling, this would be very challenging if not impossible. 

DataHub gets the job done in 8 minutes, then in the last 5 minutes we look at advanced options for encryption, authentication and methods to limit the number of open ports, including building a connection that has NO OPEN INBOUND PORTS on one side. 

OPC A&E Tunneling 

Adding the OPC A&E option to your OPC DA or OPC DA+UA Tunneler Solution Pack will add the capability to securely tunnel, aggregate and move OPC A&E classic through proxies, DMZs. You can also convert OPC A&E data to OPC DA or UA.

Modbus Tunneling

The DataHub Modbus Tunneler solution pack enables you to connect to Modbus TCP/IP devices and read/write data and convert it to OPC DA or OPC UA depending on the pack you choose or optionally both.  Add a DataHub Tunneler license to another machine on the network and move your Modbus data securely through proxies, DMZs just like any other DataHub data points.
