Syntax:
*ESR?
Response:
<nnn>
, a number from 0 to 255
Example:
32 (
an illegal command was received)
7.8.8. Set the Standard Event Status Enable Register
When one or more bits in the Standard Event Status Event Register (
*ESR,
see above)
are set, a bit can be set in the Status Byte (
*STB,
see section 7.8.5). This is done by setting
bits in the enable register. Changing the value of the
*ESE
register has no affect on the
value in the
*ESR
register
Syntax:
*ESE <nnn>
Parameter:
<nnn>
is a number from 0 to 255. The bit assignments are the
same as the
*ESR
, in the table above
Example:
*ESE 60
will cause bit 5 in the Status Byte to be set if there is a
query error, fault shut-down, execution error or a
command error
Query:
*ESE?
will return
60
in the example
7.8.9. Enable the Operation Complete
This command will cause bit 0 of the Standard Event Status Register to go to
1
when all
pending commands are completed. Because of the Genesys™ power supply architecture,
this bit will go to
1
when the
*OPC
is received, even if the output is in transition because
of a prior command
Syntax:
*OPC
7.8.10. Read the Operation Complete
This query will read back if all pending operations are completed. This query will always
return
1
, even if the DC output is in transition because of a prior command
Syntax:
*OPC?
THE SCPI ERROR AND STATUS REGISTERS
7.8.11. Read the Operational Condition Condition Register
This register reports several operating modes and settings of the power supply. Although
separate SCPI commands may also report this information, the register is beneficial
because it may allow any brief mode change to be latched into an event register for later
reading
This is a conditional register. The bits are set to “1” when the mode occurs and cleared
when the mode turns off. The values are read-only.
These are the bit assignments of the Operational Condition Condition Register:
BIT VALUE SYMBOL DESCRIPTION
0 1 CV “1” = constant voltage operation
1 2 CC “1” = constant current operation
2 4 NFLT “1” = No fault, is set when all faults cleared
3 8 0 Not used
4 16 AST “1” = Auto start is enabled
5 32 FBE “1” = Foldback protection is enabled
6 64 0 Not used
7 128 LOC “1” = Local mode, “0” = Remote mode
8 to 15 0 0 Not used
