以ControlLogix PLC系统为基础搭建的能源管控系统(EMS)需要与各生产现场第三方DCS系统做数据接口,用以提供EMS系统的数据采集和控制信号。为了完成异构通信,采用了以Modbus协议为基础的接口技术,通过ProSoft ILX56-MM、PLX31硬件支持,在实际生产中完成了数据通信采集的功能。
The Energy Management System (EMS) based on ControlLogix PLC system needs to interface with the third-party DCS system of each production site to provide the data acquisition and control signals of the EMS system. In order to complete the heterogeneous communication, the Modbus protocol-based interface technology is adopted, and the data communication acquisition function has been completed in actual production through the support of ProSoft ILX56-MM and PLX31 hardware.
