| Abstract: | A kind of experimental equipment for process control is introduced. It is a real-time monitoring system based on PLC, configuration software and VB. The execution machine is electric control valve and AC inverter. Two control methods are provided: PLC is used to compile program to control the output of the execution machine . Kingview is used to monitor PLC. The communication between VB and kingview has been realized. It provides an interface for compiling advanced arithmetic. The hardware component, software design and the method of communicating between VB and kingview are given. This system almost meets the request of the experiment for process control in universities. |
