S7 300 date or time to ascii

Hi all,

How do I convert a S7 300 PLC logged date or time to ascii, this is to be read by SCADA.

Well, there might be a function in the Simatic Library that already does that. It would be worth a look.

If you want to roll your own (and I would), all you would have to do is take each digit of the time and convert it to ASCII and construct a string. For instance, the number 7 is 55 in ASCII (just add a 48 to the number).

There are other threads here that describe the date/time format, and those would help you with the digit conversions.

Hi,
Thanks fo the info,
Just found Siemens support file #6175489 "converting DATE_AND_TIME into STRING and vice versa"

Thanks again
