Control system:

Control System: on-site controller, the next crew for the Siemens S7-1200 series PLC control system, it is a mature, stable, universal type of PLC, to suit a variety of automation applications, especially in manufacturing process control

application.

Its modular, easy to implement distributed configuration and easy to master and so on, Siemens PLC control center has become a biological reaction process control implementation is economical and advanced control system, the system uses the touch screen display, on-site direct operations (menu type), all English menu and interface; also with the host computer for data transmission, data sampling and display tank, the system view of data analysis, reading settings.

10-inch LCD touch-sensitive screen as the display screen to display complete

content-rich, user-friendly screen is simple, easy to operate. And disturbing each other. The control system can adapt to different range of sensors and actuators the output of the input signal with the signal anti-jamming system.

Software: Siemens S7+  FORCE  CONTORL

Control
1) Manual control: You can set the percentage of open valve or a valve opening

2) Automatic control mode: You can select continuous or PID PID control the switch

3) Sequence control: the control of all parameters can be pre-set at least 10 control section

4) For automatic segmentation remotely control: PC control acceptable correlation control: the dissolved oxygen can select speed, air flow rate, tank pressure, control of feeding etc.; pH can choose to control with acid and alkali...

Data Processing
1) to show that all the parameters of the trend curve analysis

2) to store, display, analyze all the historical curve parameters

3) can display all the parameters of the batch report

4) copy the data directly with the USB

5) data storage format is compatible with EXCEL, EXCEL platform can be to deal with
