The present application relates to the field of industrial automation control, and specifically provides a programmable logic controller program automatic acquisition method, a storage medium and an electronic device, aiming at solving the problem that multiple types of processor programs cannot be automatically collected. To this end, the acquisition method of the present application comprises: acquiring the type of central processing unit contained in the programmable logic controller; the type includes a standard central processing unit and a fail-safe central processing unit; according to the type, determining the program upload mode of the programmable logic controller; according to the program upload mode, uploading the program of the programmable logic controller. The present application can realize compatible collection of standard central processing unit and fail-safe central processing unit device programs, and reduce the labor cost and time cost of industrial device program operation and maintenance.

The invention discloses a dynamic configuration mapping system and method for VR head-mounted display equipment. In the invention, through the design of each sub-module of the intelligent mapping matching module, the development and maintenance cost is greatly reduced. The configuration validity verification sub-module checks the integrity of a configuration structure in advance, and running errors caused by invalid configuration are avoided; the device name matching sub-module adopts inclusion relation search instead of accurate matching, supports a device group and wildcard character form, and does not need to compile a large number of if-else codes like a traditional scheme; the mapping index positioning sub-module corresponds to equipment and configuration one by one through array indexes, new equipment only needs to add corresponding items in a configuration file, core codes do not need to be modified, the access period of the new equipment is remarkably shortened, meanwhile, the workload of regression testing is reduced, the risk of configuration conflicts is avoided, and the efficiency is improved. When the fault-tolerant degradation processing sub-module does not find the matching configuration, the wildcard character is automatically triggered to carry out the default configuration or load the default configuration, so that the interface component is ensured to be normally rendered all the time, and the robustness of the system and the user experience are improved.
