ABSTRACT:
A sequence circuit display method for an injection molding machine which enables a sequence circuit corresponding to an operating step to be quickly displayed and enables the connection states of contacts, coils, etc. in a sequence circuit to be easily grasped when obtaining a grasp of the sequence circuit, comprising selectively inputting an operating step name in an injection molding machine from an input device to thereby display a sequence circuit including contacts, coils, etc. corresponding to the selected input operating step as a ladder diagram on a display device; comprising displaying a sequence circuit of an injection molding machine as a ladder diagram on a display device and selectively inputting one of the contacts, coils, etc. in the ladder diagram to thereby display a sequence circuit including contacts, coils, etc. corresponding to the selected input contact, coil, etc. as a ladder diagram on the display device; etc.
