OPC Bridge

The OPC Bridge quickly and easily turns your DCOM OPC product into an OPC XML-DA product without requiring any programming. Whether you want to connect your standard OPC client to an XML-DA server on a Linux platform or over the Internet, or whether you want to access your DCOM OPC server with an XML-DA client - the OPC Bridge makes the connection without any loss of performance!

• OPC communication over the Internet and across firewall boundaries
• OPC bridge between Windows and non-Windows operating systems such as Linux
• No programming required

Functions

Possible applications:

From the point of view of OPC client applications, access to the configured OPC server through the OPC Bridge is fully transparent, which means that the OPC Bridge provides the namespace of the configured OPC server to a client without any changes.

Bridge between Data Access implementations

There are only minor differences between the DA 1.0, DA 2.05 and DA 3 versions. Nevertheless, the more recent versions contain extensions that are not supported by previous implementations. As no compliance test tool exists for the DA 1.0 specification, no compliance verification can be provided for DA 1.0 servers. The OPC Bridge turns a non-compliant OPC server into a compliant OPC server!

OPC clients that have control functionality but no OPC server interface (e.g. LabView) can actively transfer data to other OPC clients.

Bridge between DA and XML-DA Implementations, between DCOM and Web Services, between Windows and Linux

Substantial differences exist between the DCOM-based Data Access specifications and the Web Services- and XML-based XML-DA specification.

XML-DA servers can run on all operating systems that support Web Services. The XML-DA client and server can communicate over the Internet across firewall boundaries. The OPC Bridge connects the DCOM world with the Web Services world. The OPC Bridge always needs to be installed on a PC supporting DCOM.
