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.KFT;E26. The global status informs on the activity of the
process, 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 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.

.Req .Id1:

.Id3:

Instrument in the KFT mode, requesting Id3 after start.

.Smpl:

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

an error).
