6. Function blocks
6.1 Manufacturer function blocks
Operating principle
Each of the 32 year time switches, HY01 through HY32, features four channels that
can each be configured with an ON event and an OFF event in the parameter con-
figuration for the block. An ON time and an OFF time that are accurate to the day can
be selected for each channel. All channels act jointly on function block output Q1.
Behavior in the event of a power failure
The time and date are backed up in the event of a power supply failure and continue
to run. However, the time switch relays will no longer switch. The contacts are kept
open when de-energized.
Information on the battery back-up time are provided on → Section "Back-up of real-
time clock", page 828
Switching behavior with overlapping channel settings:
If the set ranges overlap, the year time switch activates the contact with
the first detected ON signal irrespective of which channel is supplying
this ON. In the same way, the year time switch switches the contact off
with the first detected OFF, irrespective of whether another channel still
supplies the ON signal.
Please note that the time switches can only be configured up to the year
2099.
