摘　　要：针对和利时DCS与西门子PLC系统间无法直接交互数据。以内蒙古通辽热电厂脱硫项目为例,采用Modbus通讯协议实现和利时DCS与西门子PLC系统之间的通讯。通过构建系统网络架构,硬件配置,软件组态来实现Modbus通讯。结果表明,该控制系统稳定可靠,电厂生产过程自动化水平进一步提高。Direct interaction of data is not available between hollysys DCS and Siemens PLC system. With the desulphurization project of power plant of Inner Mongolia Tongliao as an example, the Modbus protocol is adopted to realize communication between the hollysys DCS and Siemens PLC system by constructing system network, hardware configuration and software configuration. The results show stable and reliable operation of the control system and im- oroved automation control of the vower olant process production.
