The turn on and off times are entered in the format "yyyy-mm-dd hh:mm:ss". Dates can be
entered in the range from January 2000 to December 2099.
By selecting the "Yearly" and "Monthly" check boxes, you specify whether the programmed
times are evaluated yearly or monthly.
If you select the "Pulse" option, at the turn on time only a single pulse with the length of an
update cycle is set at the output instead of being permanently ON.
Switching variants from the function parameters "Yearly", "Monthly" and "Pulse"
The options for activating the function parameters result in the following switching variants.
Four typical switching variants are explained below based on examples.
● Example 1
– Date/time ON: 2015-06-15 12:00:00
– Date/time OFF: 2017-08-31 12:00:00
– "Yearly" disabled
– "Monthly" disabled
– "Pulse" disabled
Since the options "Yearly" and "Monthly" are both disabled, the settings produce a single
time during which the output is set to 1 . The time begins on June 15 2015 and ends on
August 31 2017.
● Example 2
– Date/time ON: 2015-03-15 12:00:00
– Date/time OFF: 2018-08-31 12:00:00
– "Yearly" disabled
– "Monthly" disabled
– "Pulse" enabled
Since the options "Yearly" and "Monthly" are both disabled, the settings produce a single
pulse on March 15, 2015..
