1. Control System for Biological Process
1) System Summary
BIO-4000 industrial control system is researched and developed by our company. Adopt PLC as the control unit to acquire data on site and transfer to the touch screen and PC by RS-485 signal , to realize the parameter setting, sequence control, process control and a comprehensive analysis of the various data, automatic formation of statements, control interface, touch screen direct display of the implementing agencies working conditions and parameters. It enhances the scalability and compatibility of the system because the standard MODBUS protocol port.
Lower Computer System：Adopt PLC as the control unit commands of touch screen or PC are interpreted to corresponding timing signal to directly control the corresponding equipment. Besides, equipment condition data can be converted into digital signal, and make feedback to the touch screen display or PC for further data processing.
l The software control part adopts PID close loop, which has the features of control High precision control, and the low energy consumption.
l The touch screen as a senior control source, possess the functions of password classification management, parameter setting, alarm management, real-time curve display and on-site report.
