Abstract: A method and system for obtaining link node data is provided. The method is applied to an industrial control ring network system including a master station device and a plurality of node devices, and includes: after receiving a link fault message, the master station device determines to transmit a first link location acquisition message to a first network port and/or a second network port based on respective on-off states; each node device processes the first link location acquisition message to obtain and transmit a second link location acquisition message; the master station device parses the second link location acquisition message and transmits a first node data acquisition message; the node device processes the first node data acquisition message to obtain and transmit a second node data acquisition message; and the master station device parses the second node data acquisition message to obtain data of at least one node device.

Abstract: The present disclosure discloses a method and an apparatus for data processing, a storage medium and an electronic device, where for each second unit in the embodiments of the present disclosure, a plurality of communication links are provided between the first unit and the second unit. The first unit, in response to a data operation request, sends the data operation request to the second unit through the plurality of communication links between the first unit and the second unit. The second unit processes the target data to be processed according to the data operation instruction in the data operation request to obtain a processing result, and sends the processing result to the first unit via a plurality of communication links. The first unit executes a response strategy for the data operation request based on the processing result.

Abstract: The present disclosure discloses a method and apparatus for monitoring a link state between nodes. The method includes: determining, by a first node, whether to transmit a first diagnosis message to a second node based on a monitoring result of whether to receive message data transmitted by the second node for a first time duration; processing, by the second node, the received first diagnosis message and transmitting the processed second diagnosis message to a third node; processing, by the third node, the received second diagnosis message and transmitting the processed third diagnosis message to the second node; determining, by the second node, whether to transmit the third diagnosis message to the first node; and determining, by the first node, a link state between the first node and the second node based on a monitoring result of whether to receive the third diagnosis message for a second time duration.
