Secure OT to IT Connections
 

Simply better networking

Tunnellers provide easy-to-configure, secure, and robust networking for data protocols that are difficult to connect or that rely on insecure architectures. The Cogent DataHub Tunnellers go beyond the basics, letting you integrate your data without exposing your networks.

DataHub DA Tunneller

Reliable networking of OPC servers / clients without DCOM

Do you need to collect OPC data from multiple remote locations, or connect to OPC DA servers on a different network? Now you can, easily and securely, without the hassles of DCOM, using the DataHub DA Tunneller.

What it does

  • Connects OPC Classic DA servers and DA clients over a network.

  • Eliminates DCOM problems.

  • More robust and secure than DCOM.

 

Benefits

  • Eliminates VPNs.

  • Eliminates inbound firewall ports into operations networks.

  • Quickly reconnects after network failures.

  • Multiple connections can share one tunnel to reduce network loads.

DataHub UA Tunneller

Network and Integrate OPC UA and OPC DA Servers and Clients

The DataHub UA Tunneller provides reliable networking and seamless integration for OPC UA and OPC DA (Classic) servers and clients. With a single tool you can avoid the hassles of DCOM, protect your OPC DA investment, and make a smooth transition to the IIoT and Industrie 4.0. With DataHub tunnelling you get support for HTTP CONNECT and basic proxy authentication, so IT no longer needs to change their security policies to fit OT requirements.

What it does

  • Connects OPC UA systems to OPC DA (Classic) systems, locally or over a network.

  • Enables OPC DA clients to read from OPC UA servers.

  • Enables OPC UA clients to read from OPC DA servers.

 

Benefits

  • Eliminates VPNs.

  • Eliminates inbound firewall ports into operations networks.

  • Maintains the OPC UA data model, while other gateways flatten it.

  • Multiple connections can share one tunnel to reduce network loads.

Tunnel OPC A&E

Reliable networking of OPC A&E servers and clients

Do you need to collect OPC A&E data from multiple servers at local or remote locations? Or connect to OPC A&E servers on a different network? Now you can easily and securely tunnel A&E, by adding the A&E feature to the DataHub DA Tunneller or DataHub UA Tunneller.

 

What it does

  • Aggregate data from multiple A&E servers.

  • Connect OPC A&E servers and A&E clients over a network.

  • Convert A&E to OPC DA or OPC UA.

 

Benefits

  • Integrates data from A&E servers, locally or remotely.

  • Eliminates inbound firewall ports into operations networks.

  • Maintains the OPC UA data model, while other gateways flatten it.

DataHub Modbus Tunneller

Tunnel data from Modbus TCP devices across a network

The DataHub Modbus Tunneller™ connects to any number of different Modbus TCP slave devices and allows you to easily share that data with other DataHubs across a network or Internet connection. A common use for the Modbus Tunneller is to share data between Modbus devices in one location with OPC/DDE or ODBC (database) clients in other locations, without having to deal with DCOM or Windows security permissions.

 

Benefits

  • Eliminate the need for an OPC Server to collect the Modbus data. The DataHub Modbus Tunneller includes the Modbus TCP interface.

  • Reduces communication complexities by reading the data into the DataHub and then tunnelling it to other DataHub instances.

  • Supports SSL encryption for better security.

  • Supports asynchronous socket multiplexing in Modbus TCP to share one TCP connection with multiple Modbus devices.

DataHub DDE Tunneller

Connect any DDE-enabled program like Excel across a network

The DataHub DDE Tunneller connects to any number of different DDE-enabled programs like Excel, and allows you to easily share that data with other DataHubs across a network or Internet connection. A common use for the DDE Tunneller is to share data from Excel spreadsheets across a network.

 

 

Benefits

  • Reduces communication complexities by reading the data into the DataHub and then tunnelling it to other DataHub instances, using DHTP. No need to perform protocol conversion until you connect to the client program on the other end of the tunnel.

  • Supports SSL encryption for better security.
