PROBLEM TO BE SOLVED: To provide a programmable controller capable of easily changing functions and a program development support device.SOLUTION: In each of logical sections, input sections and logical sections which are selectable as output source of signals as the objects of calculation are previously determined. In output sections, logical sections selectable as output sources of signals as the output objects are also previously determined. In each of the logical sections, contents settable as the contents of the logical operation are also previously determined. The number of the logical sections is also previously determined. When the output source and the content of logical operation are determined by an operator, a program for operating a PLC 10 is completed. |
