4.18 Daylight Savings Time
This section describes the function that automatically adjusts the Touch real time clock according to the daylight
savings time settings.
●
Feature Description
For regions where the Touch is used that implement daylight savings time, this function can automatically adjust the
Touch clock using the daylight savings time settings. When the time becomes the daylight savings time start time, the
clock is set an hour forward. When the time becomes the the daylight savings time end time, the clock is set an hour
back.
The Touch adjusts the clock for daylight savings time on the start day and the end day. However, the clock is also
adjusted for daylight savings time under the following conditions.
• When a ladder program or FBD program was downloaded to the Touch.
• When the Touch power is turned on.
When the current time of the Touch internal clock is set using System Area or special data registers, the time is not
adjusted for daylight savings time, even if the time after it was set is within the daylight savings time period. Set the
clock to the time adjusted for daylight savings time. The set date and time becomes the date and time after being
adjusted for daylight savings time.
