The Intelligent Temperature
Network Control System Based on PLC
Abstract: Current society, the information technology is developed rapidly, has already got deeply to each field, have produced great impact and influence to the traditional control mode. PROFIBUS on-the-spot bus with their of simple structure , expenses low easy to maintain , dependability high , opening ,etc. many kinds of advantage become focus of automatic field day by day technology, control with a great deal of advantage its field cause a epoch-making change in industry. This text has introduced the current situation of the development of the on-the-spot bus at first, connect the on-the-spot equipment of intelligence and two-way digital communication technology of controlling the equipment, bus live have opening and person who operate each other, some control function must following to move get on-the-spot equipment, then detailed to PROFIBUS on-the-spot bus technology. Network structure and software and hardware introducing it in detail finally are designed, and carried on research to some main control problems among them .
