In the column C1 in the table, the device number (R901A, R901A) of the auxiliary relay for monitoring the contact state is shown.
901B, R901C...) Are displayed, and of the device numbers displayed in the column C1, the shades and display colors of characters are changed according to the contact state. In this table, for example, the device number R901 of the auxiliary relay in the ON state
A, R901B, and R901C are displayed in dark characters, and the device number R of the auxiliary relay in the off state is displayed.
901D is displayed in light letters. In FIG. 3, the characters are indicated by the line type of the characters, and the characters indicated by the broken lines have a lighter display color than the characters indicated by the solid lines.

As described above, in the program creating apparatus of the present embodiment, when displaying the contact states of the relays such as the auxiliary relays in a table format, the device numbers assigned to the ON-state relays are directly displayed in the table. Therefore, compared to reading the device number by following the mark, such as when displaying the on / off state of the relay with a mark,
Since the device number can be read directly, the device number can be reliably read even when the display screen is small, and the contact state of the relay can be easily confirmed.
