摘　　要：工业通信技术是实现工业设备组网控制的有效方式,随着近些年以太网技术的发展,一种基于以太网的上层应用技术PROFINET快速发展起来,但是由于下层设备不具备高速的网络接口,需要将高速的通信协议中控制字和状态字转换为能被下层设备轻松解析的协议,进而将设备接入高速以太网。方案采用了ERTEC200P-2通信协议芯片进行外部以太网高速的数据交互,下层通过UART串行接口接入到变频器,该方案通过了试验验证,并且进行了现场验证,取得了良好的效果。Industrial communication technology is an effective way to achieve network control of industrial equipment.With the development of Ethernet technology in recent years,a top layer application technology based on Ethernet,PROFINET has rapidly developed.However,due to the lack of high-speed network interfaces in the lower layer devices,it is necessary to convert the control and status words in the high-speed communication protocol into a protocol that can be easily parsed by the lower layer devices,and then connect the devices to highspeed Ethernet.This scheme adopted the ERTEC200P-2 communication protocol chip for high-speed data exchange with external Ethernet,and the lower layer was connected to the frequency converter through the UART serial interface.The scheme has passed experimental verification and on-site verification,achieved good results.
