Kikusui PLZ-U Series Operation Manual

Status byte
register
The
status
byte
register stores STB and RQS (MSS)
messages as defined
by the
IEEE488.1 standard.
The status byte register can
be read using IEEE488.I serial
polling or 1EEE488.2 common
command
*STB?.
When serial polling
is
carried
out,
bit 6 responds to
the request
service
(RSQ). The
status byte
value
is not
changed by serial polling.
The
*STB?
query
command makes the
device
transmit the contents of the status
byte register
and
the master summary status (MSS) summary message.
The
*STB? query command
does not change status bytes MSS and RQS.
