| Abstract: | This paper elaborates the method that Siemens PLC S7-300 PID regulator module simulates without controlled object.The method of using functional modules TB41 'as regulator and functional modules and FBlOO'as output feedback to realize the simulation program of PID closed-loop regulation are proposed. Through the running of simulation,it is possible to obtain the regulation curve which is accordant with the actual system.This method is instructive to the test of PLC control system as well as the PLC experimental teaching. |
