施耐德电气一直致力提升工业以太网在可靠性、确定性和实时性等诸多方面的性能,在PlantStruxure协同自动化控制系统中,从控制层到设备层的通讯都全面基于“透明就绪”工业以太网解决方案平台。在这一平台之上,施耐德电气将在IEC61158中定义的两种实时工业以太网EtherNet/IP和Modbus TCP技术进行了无缝融合。从以太网的实时性角度来说,为了能够避免PLC程序执行周期对于数据采集实时性的影响,Unity平台控制器中集成了两块控制器芯片,分别执行程序处理和以太网通讯。通过Unity
Schneider Electric has been working to improve the performance of Industrial Ethernet in many aspects of reliability, certainty and real-time. In PlantStruxure collaborative automation and control systems, communications from the control layer to the device layer are all based on “Transparent Ready” Network solution platform. On this platform, Schneider Electric seamlessly integrates two real-time Industrial Ethernet EtherNet / IP and Modbus TCP technologies as defined in IEC61158. From the perspective of Ethernet real-time, in order to avoid the impact of PLC program execution cycle on the real-time data acquisition, the Unity platform controller integrates two controller chips to perform program processing and Ethernet communication respectively.
