<p>PURPOSE:To enable an operator to easily correct the sequence without being conscious of the sheet capacity by increasing the storage capacity to be assigned to a storage area when a sequence program stored in the storage area is changed and the number of program words exceeds the prescribed storage capacity. CONSTITUTION:A storage means 33 stores a sequence program consisting of the address of the input signal to be applied to a logical operation as well as the code showing an instruction of the logical operation. A storage control means 34 which divides the means 33 into plural storage areas for each prescribed storage capacity and storing the sequence program in division into these storage areas. Then the means 34 performs the control to increase the storage capacity to be assigned to the storage areas when the sequence program stored in the storage areas in changed and the number of program words exceeds the prescribed storage capacity. As a result, an operator can correct easily the program with no consiousness of the point of the storage area.</p> |
