The basic command command switch 4 is a switch that commands a basic command between the I / O contacts whose logical state is set by the block command switch 3, and when the AND command switch 4a is pressed, the AND command command and the OR command switch 4b are activated. When pressed, an OR command is issued.

The debug switch 5 is a switch that is pressed to debug a sequence program that has been created. When debugging is started by the debug switch 5, the block command switch 3 corresponding to each block is turned on each time the block is executed. The execution switch 6 is used when the program creation device 1 directly operates a PC (programmable controller).

A control device 8 provided inside the program creating device 1 has a processor configuration and controls the entire program creating device 1. FIG. 2 is a block diagram showing the configuration of the control device 8. The processor (CPU) 11 includes a ROM 12, a RAM 13, and an I / O via a bus 17.
Control circuit 14, interfaces (INT) 15 and 1
6 are connected. A system program is stored in the ROM 12, and the processor 11 controls the entire program creation device 1 according to this system program.

When the I / O control circuit 14 receives the signal states of the input changeover switch 2, the block command switch 3, and the basic command command switch 4, the I / O control circuit 14 converts them into signals that can be handled by the processor 11 and sends them to the bus 17.
