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.KFT .Inac: Instrument at the beginning or at the end of a titration.

.Req .Id1: Instrument in the KFT mode, requesting Id1 after start.

.Id2: Instrument in the KFT mode, requesting Id2 after start.

.Id3: Instrument in the KFT mode, requesting Id3 after start.

.Smpl: Instrument in the KFT mode, requesting sample size after start.

.Unit: Instrument in the KFT mode, requesting unit of sample size after start.

.Start: Instrument in the KFT mode, processing the start conditions.

.KFT1: Instrument in the KFT mode, titrating to the first endpoint.

.Cond.Ok: Instrument in the KFT, conditioning, endpoint reached (after the first

startup from the standby mode).

.Cond.Prog: Instrument in the KFT mode, conditioning, endpoint not reached

(Conditioning progressing).

$G .Mode.SET... As KFT.

$G .Mode.MEAS .Inac: Instrument at the beginning or at the end of a titration.

.Req .Id1: Instrument in the MEAS mode, requesting Id1 after start.

.Id2: Instrument in the MEAS mode, requesting Id2 after start.

.Id3: Instrument in the MEAS mode, requesting Id3 after start.

.Unit: Instrument in the MEAS mode, requesting unit of sample size after start.

.Meas: Instrument in the MEAS mode, measuring.

$G .Mode.CAL .Inac: Instrument at the beginning or at the end of a calibration.

.Req.Temp: Instrument in the CAL mode, requesting calibration temperature.

.Meas.Temp: Instrument in the CAL mode, measuring calibration temperature.

.Req.Buf1: Instrument in the CAL mode, requesting pH of buffer 1.

.Meas.Buf1: Instrument in the CAL mode, measures buffer 1.

.Req.Buf2: Instrument in the CAL mode, requesting pH of buffer 2.

etc.

$G .Assembly.Bur .Fill: Buret in filling process

.ModeDis: Buret in DIS mode

$G .Prep.X.Active: Preparing buret X, X=0, 1, 2.

.Empty.X.Active: Emptying buret X, X=1, 2.

In TIP, its global status as well as the step number (X) is available.

$G .TIP.X .Inac: Instrument at the beginning or at the end of a TIP.
