摘要
采用Modbus协议实现核电站计算机系统与第三方计算机系统之间的数据通讯。详细介绍了Modbus接口协议的设计与实现。通过在协议中定义开关量质量位、浮点型模拟量、从站冗余地址等方式增强了系统数据集成的安全性与可靠性。
In this paper, Modbus protocol is used to realize the data communication between the computer system of nuclear power plant and the third-party system. The paper introduces Modbus protocol interface design and realization in detail. By defining quality bit of binary variables, floating-point analog variables, redundant slave address in protocol, the security and reliability of the system data integration is improved.
