    • A peripheral device for a programmable logic controller according to the invention includes: an instruction table for correlatively storing instructions and the input/output types of parameters for the instructions; a search/discrimination means for searching the instruction table for an instruction in a code in a portion of a sequence program selected as diversion data from an existing diversion-source sequence program, to discriminate the input/output type of a parameter for the instruction; a search result creating/storing means for creating and storing a search result table by combining an address in the code in the selected portion of the sequence program, with the input/output type; a component data creating means for creating a variable data table by replacing the input/output types stored in the search result table with variable names, and for creating component data by adding the corresponding variable names to variables and to circuit information; and a component data diversion means for diverting the component data into an arbitrary position in a designated sequence program.
    • 根据本发明的用于可编程逻辑控制器的外围设备包括:用于相关地存储指令的指令表和用于指令的参数的输入/输出类型; 搜索/鉴别装置,用于搜索指令表以选择来自现有转移源顺序程序的转移数据的序列程序的一部分中的代码中的指令,以区分该指令的参数的输入/输出类型; 搜索结果创建/存储装置,用于通过将顺序程序的所选部分中的代码中的地址与输入/输出类型相组合来创建和存储搜索结果表; 一个组件数据创建装置,用于通过用存储的变量名称替换存储在搜索结果表中的输入/输出类型,并通过将对应的变量名称加到变量和电路信息中来创建分量数据来创建可变数据表; 以及分量数据转移装置,用于将分量数据转移到指定顺序程序中的任意位置。
