NJ-series CPU Unit Software User’s Manual (W501)
The Sysmac Studio or an NJ-series-compatible NS-series PT displays two event logs: the Controller
event log and the user-defined event log. The Controller logs include both the access log and the sys-
tem log. You can also display the error logs that are recorded in the CJ-series Units and EtherCAT
slaves.
The events in these logs are displayed in tables on the Sysmac Studio. Select an event from the table to
display detailed information.
If an event occurs in the Controller that is not supported by the version of the Sysmac Studio or
an NJ-series-compatible NS-series PT, the source is displayed as “Unknown” and the event
name is displayed as “Unknown Event.” The event code and attached information are displayed
correctly.
