6.1.1.4 RC - Real-time clock

242
General
easyE4 Base devices provide exactly one real-time clock
RC01.
This function block can be used to read the date and time value
of the device's real-time clock. This value is output in seven
individual parameters than can each be processed further indi-
vidually. This makes it very easy to select recurring events
with a downstream comparator function block.
Operating principle
If the function block is enabled, the date and time value from the device's real-time
clock will be output at the function block outputs: YY (year), MM (month), DD (day), WD
(day of the week), HR (hours), MN (minutes), SC (seconds).
Function block output DT signals whether the clock has been switched to daylight sav-
ing time.
