In my program I first call SFC1 READ_CLK to read the system clock. Afterwards I extract year, month and day. For today, 11th of January 2011, I get the following result: year: B#16#11 month: B#16#1 day:B#16#11 This means instead of B#16#B, which is equal to a decimal 11, the result is a decimal 17. So I somehow need to convert the hex value to a decimal value. Does somebody have an idea how to do that? I would be happy about any kind of tip how to solve this problem. Regards, Sakura

I wasn't really aware of the fact, that DATE_AND_TIME is stored in BCD format After I noticed that, I found BTI (BCD to Integer), which solves my problem... Anyway, thanks for the help Greetings, Sakura

Chilly_Garfield Posts: 316 Rating: (37)	Hi Sakura, the SCL code in STL: L B#16#11 T #test_B L #test_B UD DW#16#FF L 16 ITD MOD T #h_int L #test_B UD DW#16#FF L 16 /I L 10 *I L #h_int +I T #test_int Have fun with it.
