Execution errors are reported by the Counter after rounding and
expression evaluation operations have been taken place. Rounding a
numeric data element, for example, is not reported as an execution error.
Events that generate execution errors do not generate command errors,
device-specific errors, or query errors.
Device- or Counter-Specific Error
An <error number> in the range [
−
300 to
−
399] or [+1 to +32767]
indicates that the Counter has detected an error that is not a command
error, a query error, or an execution error; some Counter operations did
not properly complete, possibly due to an abnormal hardware or firmware
condition. These codes are also used for self-test response errors. The
occurrence of any error in this class causes the device-specific error bit (bit
3) in the Event Status Register to be set.
Query Error
An <error number> in the range [
−
400 to
−
499] indicates that the output
queue control of the Counter has detected a problem with the message
exchange protocol. The occurrence of any error in this class causes the
query-error bit (bit 2) in the Event Status Register to be set. This means
that one of the following conditions exists:
•
An attempt is being made to read data from the output queue when no
output is either present or pending.
•
Data in the output queue was lost.
