<Character String Data>
<Character string data> is not a specified character string like <Character data>. It is
an arbitrary character string. A character string must be enclosed in apostrophes (') or
double quotation marks (").
Form Example
<Character string data>
'ABC' "IEEE488.2-1987"
• Response messages are always enclosed in double quotation marks.
•I f a character string contains a double quotation mark ("), the double quotation mark
will be replaced by two concatenated double quotation marks ("").This rule also
applies to a single quotation mark within a character string.
• <Character string data> is an arbitrary character string, therefore this instrument
assumes that the remaining program message units are part of the character string
if no apostrophe (') or double quotation mark (") is encountered. As a result, no error
will be detected if a quotation mark is omitted.
<Filename>
Gives the name of a file. The format is as follows.
Form Example
{<NRf>|<Character data>|<Character string>}
1 CASE "CASE"
• If you input an <NRf> value, the system converts the value (after rounding to the
nearest integer) to the corresponding 8-character ASCII string. (If you set the value to
1, the name becomes "00000001".) Note that negative values are not allowed.
• The first 12 characters of <Character Data> are assigned as the file name.
• The first 14 characters of <Character String Data> are assigned as the file name.
• Response messages always return filenames as <character string> arguments.
<Block Data>
<Block data> is arbitrary 8-bit data. <Block data> is only used for response messages.
Response messages are expressed in the following form.
Form Example
#N<N-digit decimal value><Data byte string>
#800000010ABCDEFGHIJ
• #N
Indicates that the data is <Block data>. "N" is an ASCII character string number (digits)
which indicates the number of data bytes that follow.
• <N-digits decimal value>
Indicates the number of bytes of data. (Example:
00000010=10 bytes
)
• <Data byte string>
The actual data. (Example:
ABCDEFGHIJ
)
• Data is comprised of 8-bit values (0 to 255). This means that the ASCII code "
0AH
,"
which stands for "NL," can also be a code used for data. Hence,care must be taken
when programming thecontroller.
