6.1 Manufacturer function blocks

easyE4 devices feature a real-time clock with a date and time functionality.

When combined with the HW, HY or WT, YT function blocks, this real-time clock makes

it possible to implement the functionality of a weekly timer and year time switch.

→ Section "Time and Date setting", page 587

The AC manufacturer function block, Astronomic clock, can be used to program switch-

ing operations based on sunrise and sunset times. In order for this to work properly, the

settings for the device clock and the device location's time zone and geographic

coordinates must be correctly selected in this tab.

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.
