Execution Errors
An Execution Error is generated if a received command cannot be executed because it is
incompatible with the current device state, or because it attempts to command parameters
which are out-of-limits.
In remote operation, the EXE bit (4) is set true in the Standard-defined Event Status Byte,
and the error code number is appended to the Execution Error queue.
The error is associated with status reporting, and the queue entries can be read
destructively as LIFO by the Common query command EXQ?. There is no queue when
execution errors occur during manual operation; instead, the description of the error is
sent directly on the Menu display.
See Table 4-8 for descriptions of the execution errors.
