8-6-4 User-defined Events (User-defined Errors and Information)
An event is recorded in the event log when you create user-defined information or a user-defined error,
or when you use the ResetAlarm instruction to reset an error. When this happens, the time, event code,
event level, and attached information 1 and 2 are recorded in the user-defined event log in the event
logs.
User-defined errors are cleared when the power supply to the NJ-series Controller is turned ON. You
can also clear errors with the Sysmac Studio, the Reset User-defined Error instruction (ResetAlarm)
and an HMI.
Refer to the Sysmac Studio Version 1 Operation Manual (Cat. No. W504) for details.
