Status messages
To ensure appropriate control of an external control unit is possible, it
must also be possible to request status conditions which provide in-
formation on the status of the 732 IC Detector. The output of a status
message is triggered by the trigger
'$D'.
Status messages comprise
the global status
'$R'
and the detailed status messages listed below,
which can also appear in combination, e.g.
'$R.Cond.ProgWait'
. If a
fault appears, the error message is also appended to the status mes-
sage, e.g.
'$R.Cond.ZeroOK;E42'
.
$R
