The Design of Temperature Control System in Climatic Chamber Based on PLC and PC
In allusion to climatic chamber which is the important device in reliability and environmental test, design a control system including S7-200 PLC and PC to realize conventional PID control. To obtain more precise test temperature goal, a setting of temperature tolerance belt is imported. And introduce SIMATIC S7-200 PLC communication protocol, design a PC human-machine interface based on VC++, use a ActiveX control named MSComm6.0 to realize data recording and control between PC and PLC.
