Status System Commands
•
SYSTem:TIME?
Returns the date and time of the Model 430 Programmer in the format
mm/dd/yyyy hh:mm:ss. Time is always reported in 24-hour format.
•
SYSTem:TIME:SET <
date(mm/dd/yyyy) time(hh:mm:ss)
>
Sets the date and time of the Model 430 Programmer using the format
mm/dd/yyyy hh:mm:ss. Time is always set in 24-hour format.
•
SYSTem:ERRor?
Queries the error buffer of the Model 430 Programmer. Up to 10 errors are
stored in the error buffer. Errors are retrieved in first-in-first-out (FIFO)
order. The error buffer is cleared by the
*CLS
(clear status) command or
when the power is cycled. Errors are also cleared as they are read. See
page 130 for a complete description of the error buffer and messages.
4.5.2 Status System Commands
The status system register groups and commands are illustrated in Figure
4-1 on page 101.
•
*STB?
Returns the contents of the Status Byte register. The
*STB?
command
does not clear the “Summary Bit” (bit 6) of the Status Byte register.
•
*SRE <
enable_value
>
Enables bits in the Status Byte register to be reported in the “Summary
Bit” (bit 6) of the Status Byte register. To enable bits, you must write a
decimal
<
enable_value
>
which corresponds to the binary-weighted sum of
the bits you wish to enable. Refer to Table 4-1 on page 102 for more
information. For example, to enable quench detections only in the
“Summary Bit” of the Status Byte register, send the command:
*SRE 4;
•
*SRE?
The
*SRE?
query returns a decimal sum which corresponds to the binary-
weighted sum of the bits enabled by the last
*SRE
command.
