| Function Description |
A Library containing Functions (F) and Function Blocks (FB) for the support of DayLight Saving (DLS) in Sysmac CPU’s. This Library allows the current Sysmac CPU System Date & Time to be used to create a local time that includes DayLight Saving output Date & Time. The Sysmac CPU’s provide a Real Time Clock (RTC) with the ability to offset the internal time (GMT or UTC+0) with a Time Zone offset. However, this does not account for DayLight Saving requirements in individual countries and states. The set of tools in this Library will allow DayLight Saving to be derived and, if necessary, when setting the System Time to UTC+0 (GMT), a Time Zone & DayLight Saving can be applied. |
