Error queue
NOTE
See Section 11 for details on the error queue.
[:NEXT]?
:SYSTem:ERRor[:NEXT]? Read oldest error (code and message)
Description
As error and status messages occur, they are placed in the Error Queue.
The Error Queue is a first-in, first-out (FIFO) register that can hold up to
10 messages. After sending this command and addressing the Model
2520 to talk, the oldest message is sent to the computer and is then
removed from the queue.
NOTE
The :STATus:Queue? command performs the same function as
:SYSTem:ERRor[:NEXT]?. See
“STATus subsystem,” page 14-49 .
ALL?
:SYSTem:ERRor:ALL? Read all errors (codes and messages)
Description
This query command is similar to the [:NEXT]? command except that
all messages in the Error Queue are sent to the computer when the
Model 2520 is addressed to talk. All messages are removed from the
queue.
