The Year function block is used for yearly time functions.
The Direct Year function block has a 'from' (start) and a 'to' (end) year set by the programmer.
If the RTC is within these two years: power will flow through the function block.
If the RTC is not currently within these two years: power will not flow through the function block.
According to the above example:
Between the years 2000 - 2035 the function block will go to logic "1" (ON).
With the year 2036 the function block will go to logic "0" (OFF).
The Indirect Year function block is linked to two consecutive MIs or SIs. These integer values are entered by the user via the keypad.
If the RTC is within these two times: power will flow through the function block.
If the RTC is not currently within these two times: power will not flow through the function block.
You must create a Time Function Variable in Year (CY) format for the user to enter the start and end years.
