6.1.1.1 HW - Weekly timer (Hour Week)
easyE4 devices feature a real-time clock with a date and time functionality.
When combined with the WT, YT or HW, HY function blocks, this real-time clock makes
it possible to implement the functionality of a time switch.
General
easyE4 base devices provide 32 weekly timer HW01…HW32
(Hour Week).
Each weekly timer provides 4 channels. These channels all act
jointly on the function block output Q1 of the weekly timer.
Operating principle
Each of the 32 weekly timer, HW01 through HW32, features four channels that can
each be configured with an ON event and an OFF event in the parameter configuration
for the block. All channels act jointly on function block output Q1.
The following abbreviations are used for the individual days of the week:
Monday = Mon, Tuesday = Tue, Wednesday = Wed, Thursday = Thur, Fri = Fri, Saturday
= Sat, Sunday = Sun.
