Integration Techniques of the Embedded Distributed Systems Using Programming Environments and Industrial Standard Communication Protocols

The dispatching process and operative management of the hydro-power plants complex is based on distributed automation architectures hierarchically structured. The plant floor level - technological process interface for data acquisition is represented by programmable logic controllers (PLC) and intelligent measuring devices (embedded systems). The above mentioned devices communicate on industrial data buses with high-performance computers as the logging device. The data processing and storage create the possibility of decisions support for the energy production management and the optimization of the resources exploitation. The data communication between physical resources and structured hierarchical levels is implemented on standard communication protocols (Profibus and Modbus and others) logically driven by OPC mechanism for data source access
