  "description_excerpt": "The invention relates to an information processing technique that supports development of a project used for a control device.\n\nCurrently, a programmable logic controller (hereinafter, referred to as PLC) is widely used as an industrial control device.\n\nThe PLC controls various devices connected to the PLC by executing a preset control program.\n\nThe control program given to the PLC control is edited by an information processing device such as a PC (personal computer), as disclosed in Patent Document 1, for example. Such an information processing device is provided with a program (editing program) for creating and editing the control program.\n\n[Patent Document 1] Japanese Laid-Open No. 2016-91066\n\nFor the information processing device provided with the conventional editing program as disclosed in Patent Document 1, it is necessary to create a new control program for each controller. Further, although it is possible to simply copy one control program in the conventional information processing device, each of a plurality of control programs has to be edited individually. Therefore, even if the same editing is performed on a plurality of control programs, the same editing has to be performed individually for each control program.\n\nAs described above, with the conventional information processing device, it may take time and effort to edit a plurality of control programs.\n\nTherefore, the invention is to facilitate the editing for a plurality of control programs.\n\nIn an example of the disclosure, an information processing device includes an editing unit and a storage unit.",
