PROFINET IO-PROFIBUS PA网关设计与实现方法

Design and implementation of PROFINET-PROFIBUS PA gateway

摘要:

为研究了现场总线在工业以太网中的集成方法,提出一种从PROFINET-IO到PROFIBUS PA的网关设计方案,采用西门子EB200 IO从站卡并外接PROFIBUS PA通信驱动电路作为该网关的硬件实现方案。设计软件实现数据模型的映射和网络功能服务的映射。通过对网关进行功能和性能测试验证了其可行性,并良好的兼容于基于GSD的工程系统。

Abstract:

In order to study the integration technology of field bus and industrial Ethernet, a scheme of gateway between PROFINET IO and PROFIBUS PA is proposed. Employing Siemens EB200 IO Evaluation Board to access PROFINET IO network, the gateway is implemented with a PROFIBUS PA as an external connection driver. Correlated software packages are designed to realize the mutual mapping of data models and network functions between the two protocols. The function test and performance test prove the feasibility of the gateway. It also shows good compatibility with GSD engineering systems.
