【产品】传输性能Class D的EtherCAT®现场总线适配器,波特率为100Mbit/s
万可(WAGO)推出型号为750-354/000-001 EtherCAT®现场总线适配器,内置ID开关。该EtherCAT®现场总线适配器可将万可I/O系统与EtherCAT®相连。适配器支持所有WAGO I/O模块并可创建本地过程映像。过程映像包括数字量、模拟量模块。模拟量模块以字或字节的形式传输数据,数字量模块的数据以位的形式传输。
上面的EtherCAT®接口用于将适配器连接到网络。下面的RJ-45接口可将附加EtherCAT®设备连接到相同的总线。EtherCAT®(以太网控制自动化技术)是一个实时以太网解决方案,专为工业自动化应用而设计,具有性能高、拓扑灵活和配置简单的特点。借助EtherCAT®现场总线适配器,可以使用简单的线型或者树状拓扑结构代替昂贵的以太网星型拓扑结构。地址选择开关用于设置EDI,将固定地址分配到某个EtherCAT®从站。
