Designing and implementation of education simulation system base on PLC

This article introduces an education simulation system built on Programmable Logic Controllers (PLC). The structure and the function of the system is designed and realized according to the basic features of the PLC industrial control system, combining the information of the technique requirement and the equipment condition in a practical cement production control, etc. The article emphatically discusses the organization, implementation and adaptability of the equipment simulation subsystem and explains the essential designing principles of the equipment simulation, combined with the rotary kiln which is an important equipment in the cement production. This education simulation system has been applied to practice currently.
