Production support device, production system, and program

A terminal device (100) is provided with a start-up assistance tool (120) for classifying a plurality of remote units (400) having channels (CH) connected to a production line device (500) to be controlled into a plurality of groups, setting, on the basis of group information, an operation mode of a remote unit belonging to a specific group among the plurality of groups as a first operation mode in which operation confirmation is performed, and setting, on the basis of the group information, an operation mode of a remote unit belonging to a specific group among the plurality of groups as a second operation mode in which operation confirmation is performed. An image for displaying the operation of the remote unit belonging to the first group is created. 终端装置(100)具有启动辅助工具(120)，该启动辅助工具(120)将具有与作为控制对象的生产线装置(500)连接的信道(CH)的多个远程单元(400)分类为多个组，基于组的信息，将属于多个组中的特定的组的远程单元的动作模式设定为实施动作确认的第1动作模式，创建用于对属于第1组的远程单元的动作进行显示的图像。
