DataHub OPC Tunneller

Enabling network access to real-time data (avoiding DCOM problems).

The DataHub^® OPC Tunneller enables you to 'tunnel' data across a network, thanks to its secure, robust peer-to-peer connection model that completely avoids the DCOM and Windows security problems usually encountered when trying to network OPC data.

The DataHub OPC Tunneller keeps all OPC transactions local to the computer, thus fully protecting the client programs from any network irregularities.

The DataHub OPC Tunneller mirrors data across the network, so that both sides maintain a complete set of all the data. This shields the clients from network breaks as it lets them continue to work with the last known values from the server. When the connection is re-established, both sides synchronize the data set.

A single tunnel can be shared by multiple client applications. This significantly reduces network bandwidth and means the customer can reduce licensing costs as all clients (or servers) on the same computer share a single tunnel connection.

More features of the DataHub OPC Tunneller:

• A simple 3 step procedure gets you up and running in minutes.
• SSL networking provides a secure connection over a network or Internet connection, including optional password protection.
• The tunnelling connection works across firewall boundaries.
• The DataHub OPC Tunneller provides immediate response and automatic recovery from network interruptions and link detection timeouts can be as fast as 50 milliseconds.
• Licensing is quick and easy using software key codes. No hardware keys to worry about.
• The DataHub OPC Tunneller can connect between Windows NT, 2000, XP, 2003 and Vista.
• Unique to the DataHub OPC Tunneller is the ability to tunnel data between programs on Windows, Linux and QNX operating systems.
• A powerful built-in scripting language lets you fully customize your OPC applications by attaching custom code to process events and point changes.
• Our embedded toolkit helps you build custom tunnelling connections for any non-Windows OS that supports TCP, such as Linux, QNX, Itron, VxWorks, etc.
• Optional read and write support for Excel for accurate reporting and real-time Excel analysis of your plant data.
• The DataHub OPC Tunneller also has the ability to aggregate data from multiple OPC Servers into a common data set, giving you a single point of access to all of your plant data.
• Optional support for the latest web technologies lets you build powerful web applications for process visualization and control.
• Optional read and write access to ODBC databases so you can log data to SQL/Access/Oracle, or integrate database information into your OPC applications.
