• We recommend enabling the following events at the
corresponding registers for an SRQ message:
CME Command Error EXE Execution Error
QYE Query Error OTPA OTP Activated
TSTE Self-Test Error LIME Limit Error
OVPA OVP Activated OCPA OCP Activated
OUTE OUTput Error SEQE Sequence Error
DDTE Define Device Trigger Error
• The setting commands required to this end read as follows:
*ESE 52; ERAE 56; ERBE 190; *SRE 52.
• As soon as one of these events occurs, the KONSTANTER is
no longer able to execute the desired setting.
RS 232C Serial Interface
• Use of the SRQ service request function is not possible via the
RS 232 serial interface.
• Similar results can nevertheless be obtained.
• Set the PRE register (parallel poll enable) to the same value as
the SRE register (status byte enable register).
• Now query and evaluate the IST individual status message.
• Query and evaluation can be executed cyclically, and/or each
time data is transmitted to the KONSTANTER .
SSET, SSET? – Switching Function Signal Level
Function and manual operation:
See explanation on page 31.
Programming
Setting command: SSET txt
Parameter: txt (status)
Parameter type: Text (character)
Setting range: OFF signal output n passive high
ON signal output n active low
Example (HP Basic):
OUTPUT 713;"SSET OFF"
Signal output SIG_OUT1/SIG_OUT2 at the
analog interface generates a passive high
signal.
Query
Queries the sequence’s function status.
Programming
Query command: SSET?
Response string: SSET txt
Length: 8 characters, fixed
Parameter: txt (status)
Example (HP Basic):
OUTPUT 713; "SSET?"
ENTER 713; A$
DISP A$
→ Display: SSET OFF
START_STOP, START_STOP? – Memory Location Start and Stop
Addresses for the SEQUENCE Function
Function and manual operation:
• As opposed to manual operation, start and stop memory
addresses are entered to a command.
• See explanations on page 32 ff.
Programming
Setting command: START_STOP n1, n 2
Parameter: n1, n2 (start address, stop address)
Parameter type: Integer
Setting range: Start address: 11 to 255
Stop address: 11 to 255
Condition: Start address < stop address
Default setting: after RESET (*RST) →: unchanged
Example (HP Basic):
OUTPUT 713;"STA 20, 115"
{sequence start = address 20}
{sequence end = address 115}
Query
Displays selected start and stop memory addresses for the
SEQUENCE function.
Programming
Query command: START_STOP?
Response string: START_STOP n1, n2
Length: 18 characters, fixed
Parameter: n1, n2 (start address, stop address)
Example (HP Basic):
OUTPUT 713; "STA?"
ENTER 713; A$
DISP A$
→ Display: START_STOP 020,115
