PURPOSE:To provide a repetition data inspecting device for a ladder program for efficiently and exactly executing high-speed inspection. CONSTITUTION:The repetition data inspecting device for the ladder program to inspect coincidence/non-coincidence by writing the same data in all the addresses of a memory and comparing these written data with reference data successively while using the ladder program of a programmable controller is equipped with a means to transfer the reference data to all the areas of a destination table while using a table set instruction (TSET), a means to divide the data written in the memory into the table size of the destination table, and a means to compare the data divided into the table size with the reference data in the destination table while using a compare instruction (CMPR). |
