摘要
介绍Modbus/TCP协议的事务处理模式在SCADA采集子系统中的应用,分析多事务调度的采集方式。研究表明,采用多事务异步调用技术的SCADA采集子系统具有较高的采集率,能够保证系统高效稳定运行。
This paper introduces how the transaction processing mode of Modbus/TCP protocol can be applied in the data acquisition subsystem of SCADA system,and analyzes the data acquisition mode of multi-transaction scheduling.It shows that the data acquisition subsystem of SCADA system which adopts asynchronous call techniques of multi-transaction can achieve higher acquisition ratio,which can ensure that the system run more efficiently and stably.
