Precautions
■Clock data during initial operation
Since the clock data is not set at the factory, be sure to set the certain data.
■Configuration of clock data by a user application
Always use the C Controller module dedicated function (CCPU_SetRTC) to configure the clock data by a user application. If
another function is used, the correct clock data may not be configured.
■Clock date and time zone
The clock data range is the range when the time zone is 'UTC'.
When clock data will be changed from MI Configurator or another tool, consider the time zone setting, and then set a value
within the range.
■Operation during momentary power failure
The clock (RTC) managed by the VxWorks part continues running on battery (backup power supply) even when the power of
this product is turned OFF or a momentary power failure exceeds the allowable time. However, if a battery (backup power
supply) is not installed, clock data is not retained.
