摘要
本文针对模拟自动生产线的工作特点，提出了一种基于Profibus．DP现场总线的控制模式，着重讲述了Profibus．DP网络控制特点、构建以及技术实现的过程。整个控制系统采用Simens的s7—300作为主站，其余4个S7—200通过EM277模块挂靠在总线上，来实现整个模拟自动生产线的数据传输。这种做法大大提高了系统的可靠性和抗干扰能力。
According to the working characteristics of virtual automatic production line, the paper puts for- ward a kind of control mode based on Profibus-DP field-bus. This paper focuses on Profibus-DP＇s network control features, construction and process of technical realization. In order to complete the whole virtual data transmission of automatic production line, the whole control system adopts Simens S7-300 as the main station, and the four re- maining S7-200 are attached to the bus through the EM277 module. This approach greatly improves the system re- liability and anti-interference ability.
