12P3162X162 SLS 1508 Intelligent Logic Solver

12P3162X162 SLS 1508  with high reliability, easy to control, programming, simple to use, cost-effective, environmentally adaptable and so on, has been widely used in the control field, in the substation integrated automatic control has also been applied. But PLC in the data, information processing and image display is still insufficient, can not be compared with the computer, and thus failed to give full play to its powerful functions, generally only with PLC control of the switching volume. But in recent years, with the PLC communication network functions continue to enhance, has been able to easily connect the PLC and computer. The use of computers fast computing speed, easy information processing, display the advantages of high performance, as a host computer, the exercise of management functions, and PLC to form a hierarchical step-by-step control system with complementary advantages. In this way, the PLC can perform complex control functions, thus enabling optimal integrated control of the substation.

12P3162X162 SLS 1508 essence of the hierarchical step-by-step control idea is a large control system according to the function or structure of the hierarchical distribution of the system’s monitoring and control functions belonging to different levels to complete the functions at all levels to complete the functions assigned to it, and will be the relevant information transmitted to the upper level, accept the upper level of management. Comprehensive control functions are implemented by the highest level of decision-making, and the work of all levels is coordinated to achieve the best results of the entire control system.

12P3162X162 SLS 1508 hierarchical step-by-step control is designed according to the anthropomorphic principle of “the higher the level, the higher the intelligence, the lower the control accuracy; the lower the level, the lower the intelligence, the higher the control accuracy”. The PLC-based hierarchical step-by-step control system is divided into three levels: organization level, monitoring/coordination level and execution level.
