始于80年代末的Sercos串行实时通信系统是控制器、驱动器和分散式外围设备之间通信的一个领先的通信协议。它除了具有速度快(31.25微秒的循环周期)、精度高(500多个站点同步精度仍能达到几十个纳秒)、双环冗余数据传输和处理、SIL3安全、拓扑结构自动识别、热插拔、即插即用等卓越特点之外,还具有多种以太网协议并存于同一网络、同一循环周期内任意两个从站间的直接双向交叉通信、非特定公司专有等独一无二的特点。将近30年的数控机床、包装机、印刷机、机器人、木工机械、注塑机等苛求应用领 Sercos serial real-time communications systems, which began in the late 1980s, are a leading communications protocol for communication between controllers, drives and decentralized peripherals. In addition to its high speed (31.25 microsecond cycle), high accuracy (up to more than 500 sites can achieve tens of nanoseconds of synchronization accuracy), dual-ring redundant data transfer and processing, SIL3 security, automatic topology identification, Plug and play, plug-and-play and other outstanding features, but also has a variety of Ethernet protocols co-exist in the same network, the same cycle between any two direct cross-communication between two stations, non-specific company-specific unique features . Nearly 30 years of CNC machine tools, packaging machines, printing presses, robots, woodworking machinery, injection molding machines and other demanding applications collar
