【正文】 ges such as LD, SFC, IL available to select the language are easy to apply to the system. I used the LD (Ladder Diagram) to build the program for experiments. Figure 13 presents the main window for building the program and simulating the instruction before writing on the memory of PLC through the RS232 connecter. Every instruction in the program must be piled before writing the process code to the memory of PLC. After pilation we can simulate the program to check and explain the working of real PLC with this program and the input to simulation process can be done manually, all these processes are shown in Figure 13. 5 Experiments of PLC Trainer This trainer is designed to implement the experiments of classical control laboratory to replace the PID controller by PLC controller where the last has a wide range in industrial application. The experiments that are implemented in this lab can be divided into three main groups according to application field in classical control approach: Logic process, power system and interactive process control, where by using this trainer six experiments can be done in logic process, ten experiments in power system and eight experiments in the interactive process control. 河北大學(xué) 20xx屆本科生畢業(yè)論文（設(shè)計(jì)） 53 Every experiment has a procedure for connection on the board and program for writing with PLC memory and then run the connection.

To design and implement the system, two parts must be produced. The first is software for PLC and the second is hardware for experiments related to the programs. The PLC control system used in the design is LS industrial system pany GM7DR40A 24/16 Digital I/O and single Analog I/O module, two photoelectric sensors from Atonic pany’: the first with the model BR100DDTP, and the second BEN10MTFR. An approximate sensor with 5sides is detected, four of CMOS BCD7Segment driven by CD4511B, two relays: 2poles and 3poles, six voltages and an ammeter measurement, DC motor and 24 VDC power supply and many connecters and pinions. Satisfactory results are obtained by executing twenty four experiments for classical control theory that fulfill the requirements of control theory in undergraduate stage and replace the old experiments executed by PID controller where the practice system is implemented by PLC control now.
