<p><P>PROBLEM TO BE SOLVED: To provide a simulation support tool which can automatically generate a ladder program for test input. <P>SOLUTION: The simulation support tool is provided with a variable-extracting part 14 which analyses a ladder program of test object and extracts variables used in the ladder program; a test input sequence managing part 16 which retrieves order of execution at the ladder program, concerning input variables among the extracted variables and makes test input sequence describing a table, in which commands, variable names, normal input values of input variables are related to each input variable conforming the order of execution; and a test input ladder generating part 20 which generates the ladder program for test input, complying with the test input sequence made at the test input sequence managing part. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
