5.3.1 <CHARACTER PROGRAM DATA>
The functional element <CHARACTER PROGRAM DATA> is used to perform remote control by transferring
short alphabetic or alphanumeric data. It is defined as follows.
<program mnemonic>
Details on character data are the same as those on program mnemonics. So far, we discussed control data focusing
on numeric data. However, program data can also be used to perform control. A coding syntactical chart is as
follows.
<upper/lower
case alpha>
<upper/lower
case alpha>
<digit>
_
Data always begins with an uppercase or lowercase character, which is followed
by an arbitrary combination of characters such as uppercase characters (A to Z) or
lowercase characters (a to z), underline (_), and numeric characters (0 to 9). Since
combinations of alphanumeric characters are used as mnemonic-like symbols, the
maximum data length is 12 characters.
● <upper/lower case alpha> One of ASCII code bytes 41 to 5A and 61 to 7A (decimal values 65 to 90 and 97
to 122 = uppercase characters A to Z and lowercase characters a to z). The device
can accept a header irrespective of whether it is represented by uppercase or low-
ercase characters.
● <digit> One of ASCII code bytes 30 to 39 (decimal values 48 to 57 = characters 0 to 9).
● (_) A single ASCII code byte, i.e., ASCII code byte 5F (decimal value 95 = under-
line).
Therefore, <CHARACTER PROGRAM DATA> is program data used to transfer relatively short mnemonic-type
alphanumeric codes.
