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.
Eliminate the need for an OPC Server to collect the Modbus data. The DataHub Modbus 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 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.
Easy configuration through manual point-and-click 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 and provides client timing independence.
Other add-on features for the DataHub Modbus Tunneller include DDE/Excel support for connecting to Excel spreadsheets and other DDE servers, email/SMS notification to receive an email or SMS message based on data changes, data historian to store and retrieve large volumes of data at high speeds, data redundancy to do hot standby switching between identical data sources, and camera to stream live video or images of your system.
