Query
• A question mark is used to specify a query.
• By placing a query after a command or parameter, you can query the corresponding
command’s setting. Some commands cannot be executed as queries. For the query
syntax of each command, see sections 3.4 to 3.7.
Example 1 SR[p1]? SR? or SRp1? can be executed.
Example 2 SA[p1[p2]]? SA?, SAp1?, and SAp1,p2? can be executed.
Delimiter
• A comma is used as the delimiter.
• Parameters are separated by delimiters.
Sub Delimiter
• A semicolon is used as the sub delimiter.
• By separating each command with a sub delimiter, you can specify up to 10
commands one after another. However, the following commands and queries must be
used independently. You cannot specify them as part of a sequence of commands.
• Output commands other than BO, CS, IF, and CB.
• The YO command.
• Queries
Note: Consecutive sub delimiters are seen to be a single sub delimiter. In addition, sub
delimiters at the front and at the end of a command are ignored.
Example ;SR001,VOLT;;;SR002,VOLT;<terminator> is taken to be
SR001,VOLT;SR002,VOLT<terminator>.
Terminator
Use either of the following as the terminator.
• CR+LF ( 0DH 0AH in ASCII code)
• LF ( 0AH in ASCII code)
Note
• Do not specify a channel or relay number that is not available on the FX. If you do, an error
will occur.
• The total data length from the first character to the terminator must be less than or equal to
2047 bytes.
• Commands are not case sensitive with the exception of user-specified character strings.
• All the commands that are listed using sub delimiters are executed even if there are
erroneous commands within the list.
• Spaces that are inserted before and after a parameter are ignored. However, if spaces are
inserted before a command, after a sub delimiter, or after a query, an error will occur.
