AUTOMATIC CONTROL SYSTEM OF INDUS TRIAL SERVO BASE ON THE PLC AND MAN-MACHINE INTERFACE

Abstract PLC is in the traditional sequence controller on the basis of the introduction of the micro-electronics technology, computer technology, automatic control and communication technologies and the formation of the new generation of industrial control devices. With industrial progress, PLC control system in the industrial application of the increasingly  widespread. In  this paper,  a PLC-based  human-machine interfaces and industrial servo control system and the principles of the design  process. The control system uses the PLC will be collected at the scene encoder signal, close to switching signals, the sensor signals at different angles for each part of the working conditions so as to control various parts of action or alarm output.
