• optimizes the access of several OPC clients to one single OPC server
• minimizes the work load on the OPC server
• increases the performance of OPC communication links
• 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 Optimizer allows multiple OPC clients to access an OPC server in such a way that workload on the server is minimized. According to the definition and functionality of Data Access, every OPC client communicating with the DA server creates groups and items in the DA server. The management of many groups simultaneously as well as the processing of multiple read requests to the often identical OPC items leads to a high communication load in the OPC server.

As the name indicates, the OPC Optimizer optimizes read and write access to the items of an OPC server. Read access to identical OPC items with different update rates are combined and data acquisition from the peripherals by the OPC server is bundled using intelligent algorithms.

The configuration settings offer additional possibilities for optimization. You can specify, for example,

• that the OPC server should only read the data from the device again after the data have reached a certain age;
• that the update cycles are determined independently of the OPC clients.
