Active Workspace; Hp 5890 Inet States - HP 5890 Series II Plus Reference Manual

Signal Output
Instrument network (INET)
Except for the controller, each instrument handles setpoints for
instrument(s) other than itself only as blocks of data to be transmitted,
but not altered.

Active workspace

Each device in an INET loop provides storage area for its own setpoints
and parameters. These individual storage areas (each containing
setpoints and parameters for the specific instrument) are also available
to any other device in the loop. For example, the controller may access
them for listing and/or storage.

HP 5890 INET states

At the HP 5890, when a part of INET, the RUN LED provides indication
of INET status:
If the RUN LED is off, the INET system is in its idle state, waiting for
initiation of some action (e.g., starting a run, listing information, etc).
In this state, the HP 5890 NOT READY LED is turned on if the
HP 5890 is not ready, and/or if the INET system itself is not ready
(e.g., if a device on the loop is busy). A message SYSTEM NOT READY
will appear on the HP 5890 if some other device on the INET loop
reports not ready, and the HP 5890 is itself ready.
CLEAR
If the RUN LED is blinking, the INET system is in pre•runor
post•runoperation (e.g., a sampler cycling, a report in progress, etc).
In addition, either SYSTEM IN PRE-RUN or SYSTEM IN POST-RUN
is displayed if
the HP 5890 itself is not ready.
If the RUN LED is on, a run is in progress. The NOT READY LED is
turned on only if the HP 5890 itself should become not ready.
