摘要

只要支持所有消息，OPC UA标准就允许在非ip网络上进行连接，并允许使用备用编码方案。然而，绝大多数商业OPC UA解决方案都是基于ip和基于二进制的UA。在本文中，通过在没有安全性的ISO 11783 (CAN 2.0B)网络上发送UA二进制编码消息来分析OPC UA客户机-服务器体系结构的性能。研究发现，通过本地以太网发送和接收给定的readRequest/readResponse对平均耗时1.3 ms，通过ISO 11783网络平均耗时49.2 ms。结果表明，在使用None安全策略时，OPC UA消息的大部分序言是固定的，并且可以从数据传输中省略这些信息以减少传输的数据量。

OPC UA client-server connection over an ISO 11783 vehicle network

Abstract As long as all of the messages are supported, the OPC UA standard allows for connections over non-IP networks, and for the use of alternate encoding schemes. However, the vast majority of commercial OPC UA solutions are IP-based and UA Binary-based. In this article, the performance of an OPC UA client-server architecture is analysed by sending UA binary-encoded messages over an ISO 11783 (CAN 2.0B) network, without security. It is found that sending and receiving a given readRequest/readResponse pair took an average of 1.3 ms via a local Ethernet network and 49.2 ms via an ISO 11783 network. It is shown that much of the preamble of OPC UA messages is fixed when using the None security policy, and that this information can be omitted from the data transfer to reduce the amount of data transferred.
