Design of an Intelligent Control System based on FF Bus

In this paper, the temperature test and control system based on FF fieldbus is designed. The key matter of system structure, communication controller MCU choice, the hardware interface design and the software design are emphasized. Communication controller chip FB3050 is used with P89VS1RD2 to communicate with fieldbus, and the date can be update to PC. The design takes the full advan-tage of FB3050 to reduce software overhead and to process complicated protocols for the lower power.
