[0038] Example 1
[0039] The overall structure of the method for sharing an industrial Ethernet field bus by an Ethernet device provided by this embodiment is referred to image 3 , The data frame in the industrial Ethernet field bus enters the access device from the industrial Ethernet field bus interface 1, and the access device forwards the industrial Ethernet field bus data frame to the industrial Ethernet field bus interface 2, while passing the Ethernet data The frame type data segment distinguishes standard Ethernet data frames, and forwards the standard Ethernet data frames to the standard Ethernet interface for output. At the same time, it detects the input signal of the industrial Ethernet fieldbus interface 1, and judges whether there is data inflow through the frame synchronization and frame delimitation of the data frame. When detecting that the industrial Ethernet fieldbus interface 1 is idle and no data enters, forward the standard Ethernet interface Upload the bu...
