8 GCS Commands
C-863.12 Mercury Controller
MS249E
Version: 1.2.1
151
Format:
DRT? [{<RecTableID>}]
Arguments:
<RecTableID> is one data recorder table of the controller.
Response:
{<RecTableID>"="<TriggerSource> <Value> LF}
where
<TriggerSource> is the identifier of the trigger source.
<Value> depends on the trigger source.
Further information can be found in the description of the
DRT command (p. 149).
Notes:
Because all data record tables of the C-863.12 have the
same trigger source, the DRT? response is specified as a
single line of the form
0=<TriggerSource> <Value>
ERR? (Get Error Number)
Description:
Get error code <int> of the last occurred error and reset
the error to 0.
Only the last error is buffered. You should therefore call
ERR? after each command.
The error codes and their descriptions are listed in "Error
Codes" (p. 207).
Format:
ERR?
Arguments:
None
Response:
The error code of the last error that occurred (integer).
Troubleshooting: Communication breakdown
Notes:
In the case of simultaneous access to the controller by
several instances, the error code is only returned to the
first instance that sent the ERR? command. Because the
error is reset to 0 by the query, the error is not visible for
any further querying instance.
➢
If possible, access the controller with one instance
