3.1.3 Status messages
In order to have an efficient control by an external control device, it must also
be possible to query status conditions; they provide information on the status
of the Titrino. The trigger $D initiates output of the status. Status messages
consist of the global status, the detailed status and eventual error messages,
e.g. $S.Mode.SET;E26. The global status informs on the activity of the proc-
ess, while the detailed status conditions show the exact activity within the
process.
The following global status conditions are possible:
$G
Go: The Titrino is executing the last command.
$H
Hold: The Titrino has been held ($H, key <meas/hold> or by an error which effects
the hold status)
$C
Continue: The Titrino has been restarted actively after hold
$R
Ready: The Titrino has executed the last command and is ready
$S
Stop: A process has been aborted in an "unnatural manner". e.g. stopped or aborted
because there was an error.
Detailed status conditions
Status conditions of the global $G:
$G .Mode.SET .Inac:

Instrument in the SET mode, requesting unit of sample size after start.
.Start:
Instrument in the SET mode, processing the start conditions.
.SET1:
Instrument in the SET mode, titrating to the first endpoint.
.SET2:
Instrument in the SET mode, titrating to the second endpoint.

etc.
$G .Assembly.Bur .Fill:
Buret in filling process
.ModeDis:
Buret in DIS mode
Status conditions of the global $H:
The status message of the action which has been held appears.
If the process is held because a monitored limit has been violated, its status
message is $H.Mode.XXX.XXX.
