摘　　要：为解决松下RTEX伺服控制器的开发依赖专用通信芯片MNM1221的问题,提出了一种基于EtherMAC的新型实时伺服控制网关的设计方案。将标准性、通用性更好的EtherMAC工业实时以太网与封闭的松下RTEX协议结合起来,通过研究EtherMAC与RTEX协议的运行机制与特点,设计了一种新型伺服控制网关软硬件方案,完成了两种协议结合的关键时序设计。实现了在不使用MNM1221专用芯片的情况下,将RTEX网络嵌入到EtherMAC总线中,并能对其进行灵活的应用。经Kithara实时运动平台上实验验证,设计的网关产品满足工业控制应用的要求。Generally,the controller of Panasonic RTEX servo relies on dedicated ASIC MNM1221.To solve this situation,this paper presents a design of new real-time servo-control gateway based on EtherMAC and combines the standard real-time Ethernet EtherMAC with the closed special RTEX.By analyzing the mechanism of the two protocols,a new software and hardware solution of servo control gateway is proposed,and the key time sequence of the two protocols combination is developed.The RTEX is embedded in EtherMAC without the MNM1221,and can be used in flexible applications.The experiment on Kithara platform proves that the design can meet the industrial control requirements.
