<p>PURPOSE:To cope with the program change or design mistake quickly, by providing a P-ROM, an RAM and a debug section. CONSTITUTION:When a load is sequence-controlled with a sequence program written in a P-ROM1, if the change of the sequence program or mistake of the program exists, the sequence program read out from the ROM1 is written in the RAM3. Thus, only the defective part of the sequence program of the RAM 3 is corrected with the operation key of the debug section 4 and the load is sequence-controlled based on the corrected sequence program. Then, the trouble of key input of the sequence program at the field is avoided and the sequence program is corrected easily.</p> |
