Error Messages
Table 3–20 on page 3–181 lists some of the error messages that you may
encounter while sending commands and queries to the IntelliFrame Mainframe.
The IntelliFrame Mainframe reports the following categories of errors:
H Command Errors
H Execution Errors
H Device Specific Errors
H Query Errors
Command errors have error codes within the range of –100 and –199. These
errors indicate syntax errors. The syntax errors can be due to the command parser
detecting an IEEE 488.2 syntax error or an unrecognized header that was
received. Command errors may also occur when you attempt to send an
unemployment IEEE 488.2 common command.
Execution errors have error codes within the range of –200 and –299. These
errors are detected by the IntelliFrame Mainframe execution control block.
Execution errors can occur when a program data element following a header was
evaluated as outside of the legal input range or when the program data element is
inconsistent with the capabilities of the mainframe.
Device specific errors have error codes within the range of –300 and –399. These
errors may indicate that some operations failed to complete due to abnormal
hardware or firmware conditions.
Query errors have error codes within the range of –400 and –499. These errors
indicate that the IntelliFrame Mainframe detected a problem with the message
exchange protocol. Query errors set the query error bit in the Event Status
register. These errors may result when you attempt to read data from the output
queue when no input is present or pending. The errors may also occur when the
data in the output queue is lost.
