*OPC, *OPC? – Operation Complete Query
—
Function
The operation complete function (OPC) allows for synchronization
of the controller and the device:
Information indicating whether or not the previous instructions in
the command string have been processed can thus be evaluated.
There are two possible procedures:
Bit 0 is set in the *ESR register with the *OPC command.
Setting Command
Syntax: *OPC
A “1” is transmitted as a result following the *OPC? command.
Query Command
Syntax: *OPC?
Comment
Further evaluation options are described in the chapter entitled
“Status and Events Management”.
*PSC, *PSC? – Power-On Status Clear
—
Function
The power-on status clear flag (PSC) determines whether or not
the contents of the enable registers will be cleared when the
device is shut down.
The PSC flag can be set and queried:
Setting Command
Syntax: *PSC n
Value range: n = 0, 1
Default setting
or after RESET (*RST): 0
Query Command
Syntax: *PSC?
Sample response string: 0
Parameters List
Comment
The PSC flag setting is retained, even after the device has been
switched off or execution of the *CLS command.
*RCL – Recalling Stored Settings
RCL
Function
Settings which have been previously saved to battery-backed
memory with the *SAV command (SAVE) can be recalled and
activated with *RCL (RECALL).
Remarks
The function for recalling a device setting from setup memory can
be used for other commands by entering a text parameter (Rxx).
Example: POWER_ON R01 means that the memory content of
setup memory 1 is recalled at power-up.
Setting Command
Syntax: *RCL n
Parameters List
Register number n
n = 1 through 12
n = 99 (undo after *RST, *RCL #, ...)
Parameter type: numeric (whole number)
Recalls a parameter set from setup memory. Setting parameters
stored to the specified register number are used for the current
device settings: The status which was active before the RCL n
command was executed can be restored with the RCL 99
command.
*RST – Reset Device Settings to Default Values
ESC/LOCAL & 0
Function
After executing the reset function, the device is set to its basic
default configuration (see the table entitled “Adjustable Functions
and Parameters” in chapter 10.1).
Note: A period of approximately 30 seconds should be allowed to
elapse after the *RST command, before the next command is
executed.
