摘要
工业以太网两设备之间通信的协议主要是Modbus/TCP协议。对传统Modbus协议和Modbus/TCP协议数据帧的格式进行分析,特别为了保证工业以太网OPC监控系统数据的安全性和可靠性,提出网络接口冗余切换算法和网络接口MAC地址绑定,能保证OPC监控系统的实时安全性。在Modbus/TCP协议的工业以太网上实现水泥OPC监控系统,以OPC Server系统和OPC Client系统,两个子系统实现工业机器的参数和数据的控制,并在互连网上进行动态显示。根据动态的数据和参数,对机器进行有效的控制和操作,也可以进行远距离的查询数据,确保整个系统和机器的安全。
Industrial Ethernet communication protocol between two devices is mainly on the traditional Modbus/TCP protocol. Modbus protocol and Modbus/TCP protocol data frame format is analyzed,particularly in order to ensure the security and reliability of the data in industrial Etbernet OPC monitoring system,put forward the network interface redundancy cotangent conversion method and network inter- face MAC address binding,can guarantee the real-time and safety of OPC monitoring system. In industrial Ethernet of Modbus/TCP pro- tocol, realize cement OPC, OPC Server system and OPC Client system,implementing industrial machine parameters and data control, and displaying in the Internet dynamically. According to dynamic data and parameters,the machine can be effective control and operation,also remote data query, ensure the safety of whole system and machine.
