基于现场总线的Internet协议的应用

Application of Internet protocols for fieldbus

在自动化系统中,现场总线和基于IP技术的网络互连,使节点间能够相互传输数据,是一种比较常用的方式.文章分析了基于现场总线的网关体系结构和典型功能,并对SNMP和LDAP作为高层协议进行了研究.通过研究发现,不管是因为协议本身还是数据描述和管理的缺陷,没有一个协议是完美无缺的.

Interconnections between fieldbus system and IP - based networks had become a useful way to gain remote access to the data of the node in the automation system. We reviewed the architecture and typical functions of a gateway and discussed the application of SNMP and LDAP used as the high - level protocol. The result from the case study suggested that none of the protocol was ideally suited due to the shortcomings either the protocol itself or the way data were described and managed .
