OPC Servers Integrator (OPCSI) integrates OPC servers in a networked environment by a set of COM objects and interfaces, and a chunck of shared memory. It offers a tool for OPC programming and serves as a middelware for application development. It includes a configuration utility to help configure your OPC servers resources with OPCSI. The source code is available and you can add more features to this utility. It has the following features: * Serves as a middleware between your applications and OPC servers. * Detects, creates and manages all OPC servers in a networked environment. * Uses user-defined names to access OPC server items. * Provides direct access and cache access to OPC servers. * Uses a global shared memory to maintain shared OPC resources. * Provides an interface to access any of OPC servers. * Provides an interface to traverse the shared resources. OPCSI takes advantages of the OPC industry standard and hides complexity of COM/OPC programming. OPCSI speeds up development cycles, cuts maintenance cost, promotes increased operation efficiency, and makes OPC resources sharing available in entire enterprise environment.
