4 bytes Contains the system operating time for communication diagnostic in 8-digit hexadecimal.
00000000 to FFFFFFFF hex (unit: ms)
Query type
2 bytes Contains the query type for communication diagnostic in 4-digits hexadecimal.
0001 hex : READ ID
0002 hex : READ DATA
0003 hex : WRITE DATA
0004 hex : LOCK
0005 hex : DATA FILL
0006 hex : RF TAG OVERWRITE COUNT CONTROL
0007 hex : RESTORE DATA
0008 hex : COPY DATA
Communications
result
2 bytes Contains the error code for communication diagnostic in 4-digits hexadecimal.
(This is the upper word of the end code in response to the RF Tag communications query.)

0003 hex : Communications precaution
2001 hex : RF Tag missing error
2002 hex : RF Tag communications error
2003 hex : Tag ID mismatch error
2004 hex : RF Tag address error
2005 hex : RF Tag lock error
2006 hex : RF Tag verification error
2007 hex : RF Tag data lost error
2008 hex : RF Tag system error
2009 hex : RF Tag overwriting error
Diagnostic result
2 bytes Contains the result for communication diagnostic in 4-digits hexadecimal.
0000 hex : Normal communications
0001 hex : Insufficient power to send
0002 hex : Insufficient power to receive
0003 hex : Too much noise
0004 hex : Insufficient signal-to-noise ratio.
