Abstract
Abstract To improve searching for a net in the sequence program of a programmable controller (PC), a mark is set for a desired net (10a, 10b). Each time a forward operation key (13d) is depressed, a next (forward) net with a mark is searched for and displayed. Each time a backward operation key (13a) is depressed, a previous (backward) net with a mark is searched for and displayed. When marks are set for logically-related nets, reference can be easily made to the related nets, and thus the time needed for debugging and the like can be shortened.
