Functionality:
  • consolidates the namespaces and OPC items of multiple OPC servers in one OPC server
  • concentrates data of several OPC servers in one single OPC server
  • facilitates the management of large systems
  • saves the project engineer valuable work and time when setting up client applications
  • no programming required
  • supports OPC DA 1.0a, 2.0, 3.0, XML-DA 1.0
  • can be used as application (executable), InProc DLL or as service
  • with own Web Server diagnostic interface

The OPC Concentrator combines multiple OPC servers in one by consolidating the namespaces and OPC items of multiple OPC servers in one OPC server. This saves the project engineer valuable work and time when setting up client applications and facilitates the management of large systems.

Multiple OPC clients can access multiple OPC servers via one OPC Concentrator.

After the OPC Concentrator has been started, the name spaces of all OPC servers, defined in the configuration file, are read and integrated into the name space of the OPC Concentrator component.

Harmonizing Data Access:
Using the OPC Concentrator, several OPC Clients can access several OPC servers with different name spaces. Depending on the implementation of the vendor, OPC servers can provide a flat or a hierarchical name space. Also the structure of an OPC server's name space and the semantics to address variables in an OPC server significantly differs from vendor to vendor. Unifying resp. harmonizing the access to an OPC server's data is possible by usage of the OPC Concentrator.

Cascading of OPC Servers:
Data of several OPC servers is bundled and concentrated into one OPC server by usage of the OPC Concentrator. Data of several OPC Concentrator DLLs or several OPC Concentrator applications on several computers can be concentrated into another OPC Concentrator. That way, complex systems with a big number of OPC servers can be structured very well. Running the OPC Concentrators on different computers, which are interconnected via DCOM, can also improve the performance of the complete system.
