Separators
(1) Command program headers
Multiple messages can be written in one line by separating them with semicolons (
;
).
Example:
:ROUT:CLOSE 101;
*
OPC?
Semicolon
• When messages are combined in this way and if one command contains an error, all subsequent
messages up to the next terminator will be ignored.
• A query error occurs if a query command is combined with an immediately following semicolon (
;
)
and subsequent command.
(2) Header separator
In a message consisting of both a header and data, the header is separated from the data by a
space.
Example:
:SCAN:ADD 101
Space
(3) Data separator
In a message containing multiple data items, commas (
,
) are required to separate the data items
from one another.
Example:
:SYST:MOD:WIRE:MODE 1,WIRE2
