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.
