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 activity of the process,

while the detailed status conditions show the exact activity 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.
