This paper also introduces the mitsubishi company based on FX series programmable controller, when programming programming software FXGP/use WIN-C, make the process more concise, running speed more ideal. At the same time using Beijing the kunlun company configuration software MCGS design human-machine interface, through the man-machine interface for the control system of the real-time monitoring, real-time data sampling and processing, the constant temperature control system, so that the control system is becoming operation humanity, process visualization, automatic control field in the increasingly significant role. Through the experiment can be proven, this system applicability is very strong, good stability, accuracy, program development understandable, can adapt to industrial production in constant temperature system requirements. This article mainly introduced the constant temperature and the hardware and software of the system design.
