Network interface configuration method and device, equipment and medium

The embodiment of the invention provides a network interface configuration method and device, equipment and a medium, and belongs to the technical field of data processing. The method comprises the following steps: detecting a running state of a programmable logic controller to obtain a system running state; if the system running state is running, obtaining a data configuration mode in response to configuration information sent by the user side; if the data configuration mode is a firmware configuration mode, switching the system operation state to restart, initializing firmware configuration data of the network interface, and initializing user configuration data of the network interface; if the data configuration mode is a non-online configuration mode, switching the system operation state into a stop state, and initializing user configuration data of the network interface according to the second user downloading data; and if the data configuration mode is an online configuration mode, maintaining the system
