This command transfers data (response data) which show the results of executing 
the SEND DIAGNOSTIC command from the IDD to the INIT.  The format and 
content of response data are determined by the parameter list (page code) 
specified by the INIT in the SEND DIAGNOSTIC command. 

The “Transfer byte length” field in the CDB shows the maximum number of bytes of 
response data that can be received by the INIT by this command.  The IDD transfers 
the number of bytes of data specified by this field or all the bytes of the effective 
response data, whichever is smaller in length.  Also, when zero is specified in this 
field, this command is terminated without anything being transferred. 

 

Exercise caution in the following points when using this command. 

1.  In order to avoid damage to the results of SEND 

DIAGNOSTIC command execution (response data) from a 
command issued by another INIT during the interval until this 
command is issued, either this command should be linked to 
the SEND DIAGNOSTIC command when it is issued or the 
SEND DIAGNOSTIC command and this command should be 
executed after the IDD is reserved. 

2.  Response data are valid only when “0” is specified in the 

“SelfTest (self test)” bit and after a SEND DIAGNOSTIC 
command which specifies a specific operation in the parameter 
list is executed, with the IDD transferring response data 
showing the execution results of the latest SEND 
DIAGNOSTIC command.  Also, even if this command is 
executed, the response data in not cleared, and remains valid 
until the next SEND DIAGNOSTIC command is executed. 

3.  If this command is issued when valid response data do not exist,  

the IDD transfers a maximum of 4 bytes of X ‘00’ data to the INIT.
