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.
Notes:
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.
