    • A ladder program generating device (1) includes: a ladder chart display unit (2) configured to display a ladder chart including a plurality of program elements; a variable specification unit (3) configured to identify one program element included in the ladder chart and specify a variable included in the one program element; a program element search unit (4) configured to search the program element including the variable specified by the variable specification unit (3) inside the ladder chart; a search result display unit (6) configured to display a list of program elements searched by the program element search unit (4) as a search result; a search result storage unit (5) configured to at least store a search history by the program element search unit (4); and a search result selection unit (7) configured to select the search result to be displayed next by the search result display unit (6) based on the search history. In this device, debug operations can be easily performed in generation of the ladder program and generation efficiency of the ladder program can be enhanced.
    • 梯形图程序生成装置(1)包括:梯形图显示单元(2),被配置为显示包括多个程序单元的梯形图; 可变规范单元(3),被配置为识别包括在梯形图中的一个程序元素,并指定包含在该一个程序单元中的变量; 程序元素搜索单元,被配置为在梯形图内搜索包括由变量指定单元(3)指定的变量的程序单元; 搜索结果显示单元(6),被配置为显示由所述节目单元搜索单元(4)搜索的节目单元的列表作为搜索结果; 被配置为至少存储所述节目单元搜索单元(4)的搜索历史的搜索结果存储单元(5)。 以及搜索结果选择单元,被配置为基于搜索历史来选择由搜索结果显示单元(6)显示的搜索结果。 在该装置中,可以容易地在梯形图程序的生成中执行调试操作,并且可以增强梯形图程序的生成效率。
