Precautions
• A bus control event is registered in Windows Event Viewer after Event Log Service is started. Note that the event is not
registered when turning the power of this product OFF and ON or when Event Log Service is not running. To check a bus
control event while Event Log Service is not running, check the event in the event history screen of CW Configurator.
• Due to processing for registering an event to Windows Event Viewer, the date and time displayed in the "Logged" of an
event log, which is registered in Windows Event Viewer, may be different from the occurrence date and time of an event
displayed in the bus control event history. To check whether the same event is registered, compare the following items:
'An event code in the bus control event history'
'An event code in the dialog box of an event registered in Windows Event Viewer'
• When changing a time zone on Windows, the time in the "Logged" of event logs, which are registered in Windows Event
Viewer, is corrected according to the changed time zone. Therefore, the date and time of the event logs may be different
from that of events in the event history because time in the event history is not corrected by the changed time zone.
