4.1.3 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 KF Coulometer. 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.KFC.Inac;E26. The global status informs on the ac-
tivity of the process, while the detailed status conditions show the exact activ-
ity within the process.
The status messages are identical for all modes.
The following global status conditions are possible:
$G
Go: The KF Coulometer is executing the last command.
$R
Ready: The KF Coulometer 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.KFC .Inac:
Instrument at the beginning or at the end of a titration.
.Req .Id1:
Instrument in the KFC mode, requesting Id1 after start.
.Id2:
Instrument in the KFC mode, requesting Id2 after start.
.Id3:
Instrument in the KFC mode, requesting Id3 after start.
.Smpl:
Instrument in the KFC mode, requesting sample size after start.
.Unit:
Instrument in the KFC mode, requesting unit of sample size after start.
.Start:
Instrument in the KFC mode, waiting the pause.
.ExtrTime:
Instrument in the KFC mode, working off the extraction time.
.Titr:
Instrument in the KFC mode, titrating.
$G .Mode.KFC .Cond.Ok:
Instrument in the KFC, conditioning, endpoint reached (after the first start
from the standby mode).
.Cond.Prog:
Instrument in the KFC mode, conditioning, endpoint not reached
(Conditioning progressing).
$G .Mode.KFC .ChangeReagent:
Changing reagent.
$G .Assembly.Bur .Fill:
Buret in filling process
.ModeDis:
Buret in DIS mode
$G .Prep.Active:
Preparing buret.
.Empty.Active:
Emptying buret.
Status conditions of the global $R:
$R .Mode.KFC .Inac:
Instrument in the KFC mode, inactive.
.Cond.Ok:
Instrument in the KFC mode, conditioning, endpoint reached.
.Cond.Prog:
Instrument in the KFC mode, conditioning, endpoint not reached.
$R .Assembly.Bur.ModeDis:
Buret in the DIS mode, inactive.
Status conditions of the global $S:
The instrument gives the status from which it has been stopped. The detailed
status information is therefore identical to for the global status $G.
Violation of monitored limits with action "end" give the status message
$S.Mode.XXX.Inac;EYYY.
