A memory (,) stores a sequence program (,) expressed in a step format. Execution control device (,) executes this sequence program (,), thereby carrying out operation control on the side of a machine (,). Display control device (,) displays the sequence program (,) on a display screen of a display device (,), and displays various commands inputted by means of a keyboard (,), in the form of menus. An operator specifies a step by way of the keyboard (,), and also commands to interrupt the execution of the sequence program by way of the keyboard (,). Thereupon, execution stop control device (,) stops the execution of the sequence program in the specified step.

Message display system for programmable controller

A sequence program edit system expressed by a sequential function chart (SFC) system. When a graphic input device inputs a graphic element of a flowchart to respective blocks formed by partitioning a display screen into rows and columns, an input graphic display device displays the inputted graphic element on the display screen. On the other hand, when an insertion command is issued to an arbitrary block on the display screen by an insertion command device through a cursor, an insertion and display device automatically inserts and displays graphic elements of vertical connector lines on respective blocks in the same row as that of the arbitrary block to which the insertion command has been issued.
