*LRN? – Complete Configuration Query (LEARN)
Functions

Complete list of all configurable functions.

Complete list of all current parameter settings.
Programming
Query command: *LRN?
Response string: LRN list
Length: 202 characters, fixed
Parameter: List all configurable functions including
current parameter settings
Example (HP Basic):

Note

The controller determines the status of a current device
setting.

This information can then be used for evaluation, or for
computer controlled configuration.

A check system test sequence can first be executed manually
for all interconnected KONSTANTERs.

The device settings required for the individual test steps are
queried by the controller with the *LRN? command.

The response string can be transferred to the test program in
an unchanged fashion, and then serves as the string which will
be sent to the respective KONSTANTER.
*OPC, *OPC? – Operation Complete Flag
Settings
Functions

Allows for synchronization of the controller and the device (see
also chapter 6.3 on page 60 and the table: “Query Commands
for Status and Events Management” on page 86).

OPC follows the command which will generate a message.

After completion of the command, bit “0” OPC is set in the
standard event register ESR .

An SRQ can be generated in this way, depending upon ESE
masking.

The message is read out via the parallel interface only.
Programming
Setting command: *OPC
Example (HP Basic):
OUTPUT 713; "USET 5; ISET 3; *OPC"
Query
Functions

Are the controller and the device synchronized ?

*OPC? follows the command which will generate a message.

After completion of the command, a signal is transmitted to the
controller.

The message can be read out via the serial and the parallel
interface.
Programming
Query command: *OPC?
Example (HP Basic):
OUTPUT 713; "USET 5; ISET 3; *OPC?"
*PSC/POC, *PSC/POC? – Power-On Status Clear Flag
Settings
Functions

Response to the contents of non-volatile enable registers when
the device is switched off (see also chapter 6.5 on page 77
and the table: “Query Commands for Status and Events
Management” on page 86).
Programming
Setting command: *PSC n
Parameter: n (value)
Setting range: " 0 ": Enable registers will not be cleared.
" 1 ": Enable registers will be cleared.
Example (HP Basic):
OUTPUT 713; "*PSC 1"
Query
Functions

Status display for the PSC flag

Indicates response to the contents of non-volatile enable
registers when the device is switched off.
The PSC flag remains unchanged after switching the device off.
The PSC flag remains unchanged after the *CLR command.
Programming
Query command: *PSC?
Response string: " 0 ": Enable registers will not be cleared.
" 1 ": Enable registers will be cleared.
