• Subindex 04 hex New Messages Available gives whether there are new messages to be read.
• Subindex 05 hex Flags sets whether or not to notify the Diagnosis History as an emergency mes-
sage. It is set to 0000 hex (not notify) when power is turned ON. Write 0001 hex to send emergency
messages.
• Subindexes 06 to 19 hex Diagnosis Message 1 to Diagnosis Message 20 give the Diagnosis His-
tory. Diagnosis History is saved in Diagnosis Message 1 to 20 in ascending order. When 20 mes-
sages are saved, the 21st message is saved in Diagnosis Message 1 and the sequence starts again.
• The format of the Diagnosis History is shown below.
• The time stamp is recorded based on the time information that is obtained from the NJ/NX-series
CPU Unit. If the time information cannot be obtained from the NJ/NX-series CPU Unit, the time stamp
on the Sysmac Studio will be displayed as “1970/1/1 0:00:00”. The time stamp of a Diagnosis Mes-
sage that is saved before the time information is obtained from the NJ/NX-series CPU Unit will also
be displayed as “1970/1/1 0:00:00”.
• Subindex 01 hex Present Time for Event Log stores the time information that is distributed by the
EtherCAT master, and uses it for time stamp of the event log, i.e., Diagnosis Message.
