these variables in any mask.
You can transfer the data for the real time clock to the connected con-
troller cyclically or on request, or provide values from the controller to
the real time clock on request.
To allow the values to be exchanged, you must agree on a variable in
which the image of date and time is stored. Enter the name of this vari-
able in the system parameters of the real time clock either for setting
the real-time clock or for transferring the real-time clock to the control-
ler.
5.18.1 Date and Time Image
The time and date image describes the structure of the array variables
that must be defined for setting and updating the time.
The date and time image is exchanged in the BCD format. For the
image, you require an array variable with up to 8 bytes.
The length of the array variable is based on the length of the year spec-
ified. The following table illustrates the image with a 4-digit year:
Address + 0 H H Century (00 to 99)
Address + 1 J J Year (00 to 99)
Address + 2 M M Month (01 to 12)
Address + 3 T T Day (01 to 31)
Address + 4 h h Hour (00 to 23)
Address + 5 m m Minute (00 to 59)
Address + 6 s s Seconds (00 to 59)
Address + 7 W W Weekday (0 to 6 or 1 to 7)
