Data analysis method, device, equipment and storage medium Technical Field The present application relates to the technical field of industrial automation communications, and in particular, to a data parsing method, apparatus, device, and storage medium. Background The Modbus protocol is widely used as a serial communication protocol of an industrial control system and is widely used for data interaction among programmable logic controllers, sensors, actuators and other devices. In the context of new energy power generation, industrial automation production lines, etc., an inverter typically needs to communicate with multiple sub-devices (e.g., current sensors, temperature sensors, power modules, etc.) via a Modbus protocol. The register address distribution of the sub-devices is usually regular, but because of the difference of address space distribution rules of different manufacturers, a register mapping table is still required to be set for each sub-device independently during actual configuration, so that the cloud system can accurately analyze data. As the number of sub-devices in the system increases, the register mapping table needs to be manually updated, which significantly increases the complexity of system maintenance.
