Processing details

• These instructions convert the hexadecimal ASCII data stored in the device by the number of characters specified by (n)

after the device number specified by (s) and later to binary data, and store the converted data in the device number

specified by (d) and later.

ASCII : ASCII code (th digit)

1 to 4: 1st to 4th digit

(n): Number of characters specified by (n)

• Setting the number of characters for (n) automatically determines the range of the character string in the device specified

by (s) and the device range in which the binary data in the device specified by (d) is stored.

• Processing is performed normally even if the device range in which the ASCII data to be converted and the device range for

storing the converted binary data overlap.

• If the number of characters in the device specified by (n) is not a multiple of 4, "0H" is automatically stored after the

specified number of the last device number among device numbers for storing the converted binary data.

When the number of characters in (n) is 9

(1) 0H is automatically stored.

• If the number of characters in the device specified by (n) is 0, no processing is performed.

• The ASCII code that can be specified by (s) must be in the range from "30H" to "39H" or "41H to 46H".

Operation error

A character other than hexadecimal numerical character string (an ASCII code other than "30H" to "39H" and "41H" to "46H") is set in the

device specified by (s).

Out-of-range data is set in the device specified by (n).

• The specified number of characters is not between 0 and 16383.
