Description
1771-NIV High Resolution Analog Input Module
This project uses event-driven processing of the received information, that is, the threshold attribute is set to a non-zero value, at this time, as long as the receiving character or transmission line changes will generate the serial port event oncomm. by querying the commevent attribute can capture these communication events
1771-NIV high-temperature diffusion/oxidation system is a kind of thermal processing equipment used for diffusion, oxidation, annealing and alloying of wafers in the manufacturing process of semiconductor devices and integrated circuits, and also suitable for special temperature process treatment of other materials, and it is a kind of automatic control equipment used for long-time continuous work with high precision and high stability.
1771-NIV system for China’s semiconductor diffusion / oxidation process technology development status quo development and design, the use of advanced, reliable PLC as the control core, with a touch screen as the human-machine interface, with high-precision temperature detection circuits, the use of fuzzy self-tuning PID for the controller, can realize the complex process temperature control. It is characterized by high detection and control accuracy, good stability of working process, self-tuning of control parameters and convenient setting parameters.
