6. Function blocks
6.1 Manufacturer function blocks
6.1.1.7 WT - Weekly timer (WeekTable)
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 HW -
Weekly timer function block.
easyE4 base devices provide 32 weekly timers, WT01 through
WT32. WT weekly timers can be used to easily configure recur-
ring switching events. The function block was specifically
designed for implementing switching events that occur at set
weekly cycles.
It can also take into account different procedures for business
days and weekends.
Operating principle
Each of the 32 weekly timers, WT01 through WT032, can be configured with eight
switching events that will be executed at the same time and on any specified day of the
week. The corresponding settings are accurate to the minute and cannot be modified at
runtime, i.e., they must be viewed as a set configuration.
