一种用于实现NCUC和POWERLINK互联的总线网关装置
摘要：
本发明公开了一种用于实现NCUC和POWERLINK互联的总线网关装置，该网关装置具有两个用于连接NCUC‑Bus主站的标准IEEE1394接口，具有连接POWERLINK从站的标准网口；该网关装置包括依次连接的NCUC‑Bus通信模块、内部总线接口、MCU内部总线控制模块、数据转换模块和POWERLINK通信模块；该网关装置能作为支持POWERLINK子网的NCUC从站装置，接收NCUC‑Bus上属于本节点的数据，将NCUC‑Bus格式数据转换为POWERLINK以太网帧，并发送给POWERLINK从站；也能将POWERLINK从站返回的数据转换为NCUC‑Bus格式，发送给NCUC主站；本发明所提供的这种总线网关装置可用于标准NCUC主站与POWERLINK从站之间的双向通信。
摘要（英）：

The invention discloses a bus gateway device for achieving interconnection between NCUC and POWERLINK. The gateway device is provided with two standard IEEE1394 interfaces used for being connected with an NCUC-Bus master station, and a standard network interface connected with a POWERLINK slave station. The gateway device comprises an NCUC-Bus communication module, an internal bus interface, an MCU internal bus control module, a data conversion module, and a POWERLINK communication module which are connected in sequence. The gateway device can be used as an NCUC slave station device supporting a POWERLINK sub-network to receive data belonging to a corresponding node on an NCUC-Bus, convert NCUC-Bus format data into POWERLINK Ethernet frames, and send the POWERLINK Ethernet frames to the POWERLINK slave station, and can also convert data returned from the POWERLINK slave station into the NCUC-Bus format and send data in the NCUC-Bus format to the NCUC master station; and the bus gateway device provided by the invention can be used for two-way communication between the standard NCUC master station and the POWERLINK slave station.
