PROFIBUS PA映像分析及实现

PROFIBUSPA映像是PROFIBUSPA的重要组成部分,是PROFIBUSPA行规与通信协议栈的接口。主要分析了通用功能块映像、数据传输映像和设备管理映像。最后,讨论PA映像的实现过程,在实现中使用了缓冲队列和定时器技术,较好地解决了通信的实时性,提高了设备的智能处理能力。

The Mapping of PROFIBUS PA Profile to DP is an important part of PROFIBUS PA,and provide an interface between the PA Profile and PROFIBUS DP protocol.In this paper,the general Function Block mapping,mapping for data transfer and device management mapping were analyzed in detail.Lastly,the implementation of PA mapping was discussed.Buffered Queue and Timer technologies applied the implementation improved the real time of communication and intelligent processing capacity.
