Zusammenfassung:PURPOSE:To attain the maintenance and the inspection with no consciousness of the relationship between the corrected or inspected areas of a program and a programmable controller(PC) by providing a storage contents means which outputs the storage contents of a storage means in response to the judgement of a signal name judging means and the set-up of a condition setting means. CONSTITUTION:A storage contents output means M4 of each PC outputs the storage contents of a storage means M2 in response to the set-up of a coupling condition setting means M1. Therefore if a certain coil block is already read out of a program, the means M4 outputs the storage contents in consideration of the set coupling conditions. As a result, the precedent or next coupled PC reacts an output request and outputs its own stored program in place of the hitherto output PC at a part where a program covers both PCs in accordance with the set-up result of the means M1. Thus no consideration is required for the coupling relationships among PCs in a designing task.
