3.4 Data
<Register>
<Register> indicates an integer, and can be expressed
in hexadecimal, octal, or binary as well as a decimal
number. <Register> is used when each bit of the
value has a particular meaning. <Register> is
expressed in one of the following forms.
Form
<NRf>
#H
<Hexadecimal value made up of the digits 0 to 9 and A to F>
#Q<Octal value made up of the digits 0 to 7>
#B<Binary value made up of the digits 0 and 1>
• <Register> is not case sensitive.
• Response messages are always expressed as
<NR1>.
<Character data>
<Character Data> is a specified string of character
data (a mnemonic). It is mainly used to indicate
options and is chosen from the character strings given
in { }. For interpretation rules, refer to "Header
Interpretation Rules" on page 3-4.
Form
{EVENt|TIME|EXTernal}
• As with the header, the "COMMunicate:VERBose"
command can be used to select whether to return
the response in the full form or in the abbreviated
form.
• The "COMMunicate:HEADer" setting does not
affect the <character data>.
<Boolean>
<Boolean> is data which indicates ON or OFF, and is
expressed in one of the following forms.
Form
{ON|OFF|<NRf>}
• When <Boolean> is expressed in the <NRf> form,
"OFF" is selected if the rounded integer value is "0,"
and ON for all other cases.
• A response message is always returned with a "1" if
the value is ON and "0" if the value is OFF.

<Character String Data>
<Character string data> is not a specified character
string like <Character data>. It is an arbitrary
character string. The character string must be
enclosed in single quotation marks (') or double
quotation marks (").
Form
<Character string data>
• If 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.
• A response message is always enclosed in double
quotation marks (").
• <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 single (') or double quotation
mark (") is encountered. As a result, no error will
be detected if a quotation mark is omitted.
<Block Data>
<Block data> is arbitrary 8-bit data. It is only used in
response messages on the TA720 and is expressed in
the following form.
Form
#8<8-digit decimal number>
<data byte sequence>
• #8
Indicates that the data is <Block data>.
• <8-digit decimal number>
Indicates the number of bytes of data (example:
00000010 = 10 bytes).
• <data byte sequence>
Expresses 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 the
controller.
Example
'ABC' "IEEE488.2-1987"
Example
#800000010ABCDEFGHIJ
