Additional Information
• You cannot check the error logs that are managed independently by EtherCAT slaves because
they are not for Controller events. Refer to relevant manuals for the slaves for the procedures
to read error logs and correct errors.
• Error causes and corrections are not displayed on the Controller Event Log Tab Page in the
Sysmac Studio, although error codes, which are registered in the error logs that are managed
independently by CJ-series Special Units, are displayed. Refer to relevant manuals for the
Units for the procedures to read error logs and correct errors.
 User-defined Events
These are events that occur in applications that the user developed.
Refer to the NJ/NX-series CPU Unit Software User's Manual (Cat. No. W501) for information on
user-defined events.
Non-fatal errors are managed as Controller events. This section describes mainly the Controller events.
Details on Controller Events (Errors and Information)
 Controller Event Times
The time of occurrence is recorded when an event occurs.
The times of occurrence are based on the CPU Unit's built-in clock data.
For events that occur in EtherCAT Slave Terminals, the times of occurrence are recorded based on
the CPU Unit's built-in clock data that the EtherCAT Slave Terminal receives from the CPU Unit.
If the EtherCAT Slave Terminal cannot obtain the clock data from the CPU Unit, the time of occur-
rence on the Sysmac Studio is displayed as ----/--/-- --:--:--. For an event occurred before the Ether-
CAT Slave Terminal obtains the clock data from the CPU Unit, the time of occurrence is also
displayed as ----/--/-- --:--:--.
Version Information
If the EtherCAT Slave Terminal cannot obtain the clock data from the CPU Unit or an event
occurred before the EtherCAT Slave Terminal obtains the clock data from the CPU Unit, the time
of occurrence is displayed as 1970/1/1 0:00:00 with Sysmac Studio version 1.14 or lower.
 Sources of Controller Events
The Event source information indicates the location where an event occurred. The event source
identifies the particular function module in the CPU Unit in which the event occurred. For some func-
tion modules, there is more detailed information about the event source. This information is called
the Source details. The following information is provided as the event source details.
