• Subindex 04 hex (New Messages Available) provides notification of new messages. It indicates if
the error log has been updated. When the error log is updated, the value changes to 1 (TRUE). The
value changes to 0 (FALSE) in the following cases.
a) Subindex 03 hex (Newest Acknowledged Message) gives the subindex number of the most re-
cent error log record.
b) The error log has not been updated.
• Subindex 05 hex (Flags) is the control flags for the error log. Use this to specify whether to enable or
disable notification of errors by emergency messages. Set this to 0001 hex to enable notification, or
0000 hex to disable notification. This is set to 0000 hex (disable emergency notification) when the
power supply is turned ON. Even if it is set to disable notification, the error log records will be saved
for errors that are described to be saved in 11-5-4 List of Emergency Error Codes on page 11-27.
• Subindexes 06 hex to 45 hex (Diagnosis Message 1 to 64) give the diagnosis messages.
Subindex 06 hex (Diagnosis Message 1) to subindex 45 hex (Diagnosis Message 64) store up to 64
errors as they occur. The 65th error is stored by returning to subindex 06 hex (Diagnosis Message
1).
• The following table gives the format of a diagnosis message.
The presence of the flag parameters 1 to 4 and detail parameters 1 to 4, and the number of parame-
ters if they are present, are determined depending on the event type. The bits 8 to 15 of the flag
indicate the presence and quantity.

Write the number of the error log record between 06 and 45 hex. The value of subindex 04 hex
(Newest Messages Available) changes to FALSE.
If you write 00 hex, the entire error log is cleared.
If you write values other than 00 hex and 06 to 45 hex, the abort code 06090030 hex is re-
turned. If you write a subindex that does not have an error log record, the abort code 06090030
hex is returned.
