5.2.4 Status messages
To ensure appropriate control of an external control unit is possible, it
must also be possible to request status conditions which provide infor-
mation on the status of the 788 IC Filtration Sample Processor. The
output of a status message is triggered by the trigger '$D' . Status
messages consist of the global status, the detailed status and eventual
error messages. 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 IC Filtration Sample Processor is executing the
last command.
$H Hold The IC Filtration Sample Processor has been held
($H, key, or by an error which effects the
hold status).
$C Continue The IC Filtration Sample Processor has been re-
started actively after hold.
$S Stop A process has been aborted, e.g. by pressing the
key or because there was an error.
$R Ready The IC Filtration Sample Processor has executed
the last command and is ready.
Detailed status conditions
Status conditions of the global $R:
$R.Mode Basic state: ready to start automatic processing
$R.Assembly An assembly step has been executed.
Status conditions of the global $G:
$G.Mode.Start. Instrument at the beginning of processing
$G.Mode.Start.01.WAIT Instrument processing the start sequence, dis-
plays line number and current command
$G.Mode.Sample.01.WAIT Instrument processing the sample sequence,
displays line number and current command
$G.Mode.Final.01.WAIT Instrument processing the final sequence, dis-
plays line number and current command
$G.Mode. Instrument processing a manual command
$G.Assembly. Instrument processing an assembly command
Status conditions of the global $H:
$H.Mode The status conditions of the global $H are identical with the
ones of the global $G.
