Hello
STW225 is the value of the days past since 1-1-1984(hexadecimal)
V2308 is the integer value of the days past since 1-1-1980
V2309 is the integer value of the minutes past since midnight.
V6125 is the integer value of the current year(value is now 2009)
V6126 is the integer value of the current month (value between 1 and 12)
V6127 is the integer value of the current day of the month (value between 1 and 31)
This special function works with 555 and 2500 plc,s, I don’t know if there is a huge difference with the older 565 plc.
Of course this is only possible if your cpu can handle special functions and I remember that the old 560 cpu could only run ladder.
The 565 was about the same cpu as the 560 but it had an extra special function cpu board installed in the base besides the normal cpu.
Hope this will help you?
Regards
Henny
