Abstract
A control method and device (100) based on an industrial Ethernet relate to the technical field of Ethernet. The industrial Ethernet involves a master node and a plurality of slave nodes. The master node transmits a predetermined packet to a first slave node (S140). The first slave node transmits the predetermined packet having been rewritten by the first slave node to a succeeding slave node linked to the first slave node until a last slave node in the plurality of the slave nodes receives the predetermined packet having been rewritten by all preceding slave nodes in the plurality of the slave nodes; and the last slave node transmits the predetermined packet back to the master node (S150). The master node then parses the predetermined packet, which has been rewritten by each of the plurality of the slave nodes, to uncover a topology of the slave nodes (S160). The master node informed by the topology transmits a command packet to one of the plurality of the slave nodes to be controlled (S180). As is shown, the predetermined packet transmitted by the master node is sequentially rewritten by the plurality of the slave nodes so that the master node can be informed of the topology of t…
