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 this range, power will flow through the function block.
According to the above example:
Between the years 2002 - 2005, power will flow through the function.
The Indirect Year function block is linked to two consecutive integers. These integer values are entered by the user via the controller keypad.
If the RTC is within these two times: power will flow through the function.
If the RTC is not currently within these two times: power will not flow through the function.
You must create a Time Function Variable in Year (CY) format for the user to enter the start and end years.
To select the year using the controller's keyboard, the operator uses:
Up and Down scroll arrow keys to scroll through the years
Enter key to select the desired year
