196单片机与WorldFIP现场总线的通信开发

Design of WorldFIP Fieldbus Communication with 196 Singlechip

MICROFIP是基于WorldFIP的现场总线通信控制器,能与微控制器和总线介质方便的接口,并能实现WorldFIP现场总线通信协议、介质冗余管理等,因此广泛使用在WorldFIP总线产品中。文章介绍了WorldFIP现场总线通信协议的特点,着重介绍通信控制器MICROFIP的特性,并给出196单片机与MICROFIP的通信实现,包括接口和软件设计。

MicroFIP is a communication chip based on the WorldFIP fieldbus, which can interface with the microcontroller conveniently, and realize the protocol of WorldFIP and the management of the medium redundancy, and which is widely used in the products of fieldbus. This paper introduces the communication protocol of the WorldFIP filedbus, and emphasizes the feature of the communication chip MICROFIP, and gives the realization of communication between the 196 singlechip and MICROFIP, including the interface and the software.
