Embodiment 1
[0047] Embodiment 1: According to the patent, a new type of industrial real-time Ethernet EtherMAC (Ethernet for Manufacture Automation Control) is implemented on the device, which can support up to 254 slave nodes, without any relay nodes The maximum transmission distance between them can reach 100 meters. Using the synchronization and time synchronization method described in the patent "A Device and Method for Realizing Synchronization between Ethernet Chain Network Nodes" (Patent No.: ZL200710014419.2), the nodes can A synchronization accuracy of less than ±100ns is obtained.
Embodiment 2
[0048] Embodiment 2: Load the Powerlink slave station IP core into the core board FPGA, and cooperate with different servo drive interface boards to realize a standard servo slave station supporting Powerlink.
Embodiment 3
[0049] Embodiment 3: Load the EtherCAT slave station IP core in the core board FPGA, or add an EtherCAT Ethernet chip on the core board, and then cooperate with different servo drive interface boards to add an EtherCAT interface for the general servo.
