SPECTRUM POWER SIEMENS Sinaut (Siemens Network Automation) Spectrum(Applications Spectrum), is a Distributed Control System, where each application does a specific function. UI or MMI: Display and Logging, this is the Human Machine Interface. DAS/TIF: Data Acquisition System, is the Front End Processor or interface between the SCADA System and the RTUs or PLCs remotes. SDM/ADM: Source Data Management, this includes the DBA and the management of data base static and Operational. RTC/COMM: The real time Communicators are servers to manipulate the data base in real time (alarms, colouring, commands, etc) and is the system buffer. DBA: Data Base Administrator and HFD (historical and future data). Expert System: Application Programming Interface. NA: Network Analysis, application for analysis in the Power Network (short circuit, State Estimator, Dispatch Power Flow, etc). DTS: Dispatcher Training Simulator. Demand Side Management: Optimization.
