DataHub Modbus Tunneller
Tunnel data from Modbus devices across a network
The DataHub Modbus Tunneller ™ connects to any number of different Modbus TCP or RTU 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.
You can
- Tunnel Modbus data directly from device connections.
- Eliminate the expense of an OPC Server to collect the Modbus data.
- Integrate Modbus devices into any DataHub-based system.
Unique Advantages
- Reduces communication complexities by reading the data into the DataHub and then tunnelling it to other DataHub instances. 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.
- Connects directly to Cogent DataHub service for Azure for networking plant data between remote locations.
- Easy configuration through manual point-and-click or XML file import.
- Unlimited number of tunnel connections per DataHub instance.
- Supports asynchronous socket multiplexing in Modbus TCP to share one TCP connection with multiple Modbus devices. This eliminates cross coupling between client timeouts and provides client timing independence.
