Data processing method and device of industrial control system, and storage medium

The invention relates to a data processing method and device of an industrial control system and a storage medium, the industrial control system comprises a controller and at least one input module, the output end of the at least one input module is connected with the input end of the controller, and the method comprises the steps that the at least one input module receives a data synchronization command, the data synchronization command comprises a starting moment of a next control period in the controller; in response to the data synchronization command, acquiring a planned moment for sending data to the controller; and sending data to the controller at the planned moment under the condition of determining that the duration of the planned moment earlier than the starting moment is less than a preset duration range. According to the invention, the synchronization of the data sent by the plurality of input modules to the controller can be realized through the control period, the average response period of the
