Abstract: The design include the intelligent industry controller used for lower level computer and the monitoring program used for upper level computer by the kingview 6.51,they take the Modbus for communication which is one of the popular industry field bus protocol. This controller use the advanced intelligence Expert PID controlling arithmetic for the control of temperature, pressure, liquid level,humidity and etc.The latter can read-write and display the parameter of the lower level controller, give an alarm , print report forms and etc.They implement a suit of integrated and credible industry monitoring system which is proved well by the factory practice.It will have a good application foreground.
