SCPI Command Reference 5-61
:QUEue commands
[:NEXT]?
:STATus:QUEue[:NEXT]? Read Error Queue
Description As error and status messages occur, they are placed into the Error Queue.
This query command is used to read those messages.
The Error Queue is a first-in, first-out (FIFO) register. Each time you read the
queue, the “oldest” message is read and that message is then removed from
the queue. The queue will hold up to ten messages. If the queue becomes full,
the “350, ‘Queue Overflow” message will occupy the last memory location
in the register. On power-up, the Error Queue is empty. When the Error
Queue is empty, the “0, ‘No error” message is placed in the Error Queue.
The messages in the queue are preceded by a number. Negative (-) numbers
are used for SCPI defined messages, and positive (+) numbers are used for
Keithley defined messages. The messages are listed in Appendix B.
After this command is sent and the Model 2010 is addressed to talk, the
“oldest” message in the queue is sent to the computer.
NOTE The :STATus:QUEue[:NEXT]? query command performs the
same function as the :SYSTem:ERRor? query command (see
System subsystem).
:CLEar
:STATus:QUEue:CLEar Clear Error Queue
Description This action command is used to clear the Error Queue of messages.
