B-12
MST 488-27 013004
Description: Posts error messages to the output queue. Returns the next error number followed by its corre-
sponding error message string from the instrument error queue. The error queue is a FIFO (first in first
out) buffer that stores errors as they occur. As it is read, each error is removed from the queue and the
next error message is made available. When all errors have been read, the query returns 0,"No error".
If more than 15 errors are accumulated, it will overflow. The oldest errors stay in the queue but the
most recent errors are discarded. The last error in the queue will be -350,"Too many errors." Error
messages are defined in Table B-6.

SYSTem:LANGuage
COMMAND
SYST:LANG
Syntax: Short Form: SYST:LANG CIIL Long Form: SYSTem:LANGuage CIIL
Description: This command allows the CIIL command language to be used to program the power supply.
(CIIL is included to provide compatibility with earlier Kepco equipment.) Once CIIL is selected, the CIIL
command ‘GAL’ followed by the command ‘SCPI’ must be sent for the power supply to respond to
SCPI commands.
TABLE B-6. ERROR MESSAGES
ERROR MESSAGE
ESR ERROR BIT SET
(SEE PAR. A.5)
EXPLANATION
0,“No error” None No error
-100,“Command error”
Command Error bit 5
Command and data understood, but more information included
which is not recognized.
-102,”Syntax error”
Command Error bit 5
First 4 characters recognized, subsequent characters not rec-
ognized.
-103,”Invalid separator” Command Error bit 5 For example, VOLT.10 received instead of VOLT:10
-108,”Parameter Not Allowed Error” Command Error bit 5 Volt12 sequence, channel number is invalid
-109,”Missing parameter” Command Error bit 5 For example, VOLT instead of VOLT 21.
-111,”Header seperator error” Command Error bit 5 Missing space between volt and value or ; missing
-113,”Undefined header”
Command Error bit 5
First 4 characters could not be identified as legal com-
mand.For example, command VLT instead of VOLT
-120,”Numeric data error” Command Error bit 5 Expected number but other characters were detected
-121,”Invalid character in number” Command Error bit 5 Volt 1,500 ( comma not allowed)
-123,”Exponent too large” Command Error bit 5 Exponent E+3 or greater is invalid.
-141,”Invalid character data”
Command Error bit 5
For example OUTP OFD or OUTP STOP instead of OUTP
OFF

Command Error bit 5
Invalid characters were detected in numeric entry.For example
E.1 instead of E+1 or 4d3 instead of 4.3.
-222,“Data out of range” Execution error bit 4 Value exceeds power supply rating
-223,”Data format error” Execution error bit 4 Multiple decimalls in digit, Multiple E, etc.
-224,“Illegal parameter value” Execution error bit 4 For example, OUTP 2 instead of OUTP 1
-241,”Hardware missing” Execution error bit 4 Requesting device 2 status (INST:NSEL 2)
-350,”Queue overflow” Device Error bit 3 (1) More than 15 errors are in queue.
-410,”Query interrupted”
Query Error bit 2
New command sent before data from previous query read.
Previous query data lost.
-430,”Query Deadlocked“ Query Error bit 2 Over 255 characters received in single input string"
(1) The Device error bit may be set when the status monitoring functions of the power supply detect an overvoltage/under-
voltage condition.
