Assessment of industrial data network standards

An assessment is presented of MAP (manufacturing automation protocol), PROWAY, and field buses, from the viewpoint of eventual power generation applications. The standards are investigated as to how they meet the power generation control network´s requirements. Such requirements as high-quality functionality and fast performance are indispensable to ensure tight information consistency for the power plant distributed digital control. Difficulties and shortcomings are discovered in each stand, MAP is not redundant, expensive, and, because it is broadband, it is very slow. PROWAY´s access time is variable and unpredictable except that it consistently takes more time when speed is of greater importance. The field bus is still not fully developed or standardized, and so was difficult to accurately evaluate
