6. Function blocks
6.1 Manufacturer function blocks
6.1.1.6 YT - Year time switch (Year Table)
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
This function block is an enhanced version of the existing HY -
year time switch function block.
easyE4 base devices provide 32 year time switches (new),
YT01 through YT32.
Year time switches can be used to easily configure unique or
recurring switching events.
The following operating modes are available within this con-
text:
l
Fixed date
l
Fixed date for every year
l
Weekday rule
l
Easter rule
Variable holidays other than Easter cannot be selected.
Operating principle
Each of the 32 year time switches, YT01 through YT32, features eight channels that can
each be configured with an ON event and an OFF event in the parameters for the func-
tion block. All channels act jointly on function block output Q1.
