基于Profibus-DP总线的变频器与集散控制系统通信的开发与应用

The Development and Application of Inverter and DCS Based on Profibus-DP

主要采用Profibus-DP现场总线实现EV2000变频器与国产ECS-100分布式自动化控制系统实时通信的方法。通过Profibus-DP现场总线,采用主从站的方式组成了单主Profibus-DP通信系统,通过ECS-100总线接口卡件FW239(主站)周期性与变频器进行数据交换和控制指令,实现了对变频器的控制和驱动设备的操作,方便了工艺人员和操作人员。

Using Profibus-DP to realize the communication between EV2000 frequency inverter and domestically-made ECS-100 DCS（distributed control system） is introduced.Single-bus Profibus-DP communication system is established with master/slave setup to cyclically exchange data with the inverter and give control instruction to the inverter through ECS-100 bus interface card FW239（master）,realizing control of the inverter and operation of the driving device which provide convenience to the technicians as well as operators.
