The Developmental Design of the Intelligent Slave Station Based on the Profibus-DP Fieldbus

As the communication network used to connect the automation equipment like instrument and controller in the manufacturing field, the fieldbus technology is a new distributed control technology appeared during ninetieth decade. Accompanied with the digital period coming, the fieldbus control will become the main trend in the industrial automation. It designs the intelligent slave based on Profibus-DP field bus technology in this paper. It consists of the design of microprocessor and communication interface chip, and the implementation of the remote control.
