基于FDT技术的Modbus规约设备DTM研究和开发

Research and Development of Modbus Device Type Manager Based on FDT

FDT是现场设备与控制系统或工程和资产管理工具之间进行数据交换的一种标准化的接口规范,支持目前主流的大部分现场总线协议,如Modbus、Profibus、CC-Link、HART等。DTM是一种由设备制造商开发的软件组件,包含设备相关的应用软件。主要介绍基于Modbus协议的设备DTM的开发步骤。

FDT is a standard interface specification in the exchange between filed device and control system.The FDT support most of all filed protocol,such as Modbus,Profibus,CC-Link,HART and so on.DTM is a software object which is developed by device manufacture.This paper describes the development of DTM base Modbus protocol.
