This section explains the effects of altering the day change time after schedules, such as power schedules or job net schedules, have been set up.
Effects on power schedules
If the day change time is changed to within a defined operation range, the operation range is split into two operation times, and the new ranges will be registered. Accordingly, the power on date/time and shutdown date/time may change. After the day change time is changed, check the work start and end times for each pattern.
If the day change time was set in a range between the time in Work end time if next day is a holiday of the Power Control Pattern dialog box and 30 minutes prior to that time, the work end time will be invalid. Additionally, if the day change time was set in a range between the time in Work start time if previous day was a holiday of the Power Control Pattern dialog box and 30 minutes after that time, the work start time will be invalid.
If the day change time is changed to a time between the times set for Work start time if previous day was a holiday and Work end time if next day is a holiday, note that, compared with the pre-change operation, the work start time for when the previous day is a holiday and the work end time when the next day is a holiday will be delayed by 24 hours. If this causes an operational problem, either restore the original day change time, or change Work start time if previous day was a holiday or Work end time if next day is a holiday according to the operation.
Effects on schedules for job nets
If the day change time is altered after job nets have been registered, the job nets for all users will be rescheduled.
The relationships relative to the execution time will change, which may cause the scheduled startup day for the job net to change. After altering the day change time, check the scheduled startup days.
If Execution interval is specified as the job net execution condition, the day change time must not be set between the start and end times. Otherwise, the job net may no longer start at regular intervals. After the day change time is changed, check the start and end times.
