Tunnel data from Modbus TCP devices across a network

With the DataHub Modbus Tunneller, connect any number of different Modbus TCP slave devices and easily share that data with other DataHub nodes 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:

  • Private cloud ready
  • Eliminate the need for an OPC Server. The DataHub Tunneller includes the Modbus TCP interface needed to collect your data. You can then tunnel the data without having to convert it into OPC. This saves time and money as you don’t need to purchase an OPC Server to read from the Modbus devices
  • Reduces communication complexities
  • 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
  • Easy point-and-click configuration or XML file import
  • Supports asynchronous socket multiplexing in Modbus TCP to share one TCP connection with multiple Modbus devices
    • This eliminates cross coupling between client timeouts
    • Provides client timing independence
  • Use our built-in scripting tools to customize your installation and monitoring needs
