ERROR? – List of Error Messages
Menu
Function
The three last different error messages can be read out with this
command. The content of the µC-RSTSRC registers is added as
the fourth parameter
The error list can be reset with the *CLS command.
A description of the errors is included in the section entitled
“System Messages”.
Query Command
Syntax ERROR?

Parameters List
FSET, FSET? – Sequence Function Parameter
Menu
Function
In addition to USET, ISET and TSET, FSET is the fourth parameter
for defining the sequence memory.
It determines which function will be executed upon transition to
the respective memory location.
Execution of the parameter is only possible during the course of a
running sequence (similar to the TSET parameter).
When the FSET parameter is transmitted, the current FSET
setting is determined and is saved to the respective specification
by means of the SM_STORE command.
The parameters for the FSET command are also part of the
STORE command.
Setting Command
Syntax: FSET txt
Default setting
or after RESET (*RST): CLR
Query Command
Syntax: FSET?
Sample response string: FSET NF
Parameters List
IFC – Resetting the IEC Bus Interface (interface clear)
—
Function
The IEC bus interface at the device is reinitialized with the IFC
(INTERFACE CLEAR) bus interface command, and is returned to
the standard default settings.
Addressing status Not addressed
Input and output buffers Unchanged
Service request SRQ Unchanged
Status byte register STB Unchanged
Event registers ESR, ERA, ERB, ERC Unchanged
Enable registers ESE, ERAE, ERBE, ERCE, SRE, PREUnchanged
Set and stored parameters Unchanged
Setting Command
Syntax: IFC
Param-
eter
Content Meaning
n1 031 Command error, CME (last error)
n2 098 Max. limit overflow (next to last error)
n3 000 No further errors
n4 001 The content of internal register µC-RSTSRC is added as additional
information, although bits D7 through D5 are irrelevant. The value is
not influenced by the “*CLS” command.
Param-
eter
Content Meaning
txt
CLR Empty memory location, is ignored/skipped during execution.
CLR in the data record of the stop address of a sequence switches
the output off after the sequence has been completed.
NF Sequence values USET, ISET and TSET without additional function
(switching function)
RU Voltage ramp, duration TSET or TDEF
RI Current ramp, duration TSET or TDEF
SOFF Additionally switches SSET to OFF
S_ON Additionally switches SSET to ON
AUOF Additionally switches analog input UEXT to OFF
AUON Additionally switches analog input UEXT to ON
AUSS Additionally switches analog input UEXT to SSET control
AIOF Additionally switches analog input IEXT to OFF
AION Additionally switches analog input IEXT to ON
AISS Additionally switches analog input IEXT to SSET control
Rxx Sequence chain; USET/ISET/TSET are ignored; new device setup is
loaded from setup memory xx (see *RCL n command)
! Thus all settings and parameters saved to Rxx apply.
Additional chains are also possible, but without automatic return
upon reaching the stop address.
Value range: R01 to R12
Sxx Invoke subsequence; USET/ISET/TSET setting is ignored;
! Only the START_STOP, REPETITION and TDEF parameters from
setup memory xx are used.
Automatic return to the main sequence when the stop address of
the subsequence is reached after the specified number of
repetitions has been completed.
No return occurs if continuous repetition has been selected for the
subsequence.
Maximum nesting depth: 1
Value range: S01 to S12
