Hello Ajay; First, you need to complete your byte coding so you can add Microseconds and Day of the week fields so that you can convert them to a Date_and_time variable. How can you read out the date and time with SFC1 (READ_CLK) and set them with SFC0 (SET_CLK)? https://support.industry.siemens.com/cs/us/en/view/21222026 Once the format of your byte fields is corrected (look out for the Microseconds byte format, it occupies one full byte + the MDBs of the next byte, Day of the Week; one easy way to do so is t=o force the value of the Microseconds byte to b#w#0), all you need to do is create a Date_and_Time variable in one of your DBs and Move all those bytes to this variable. You will then be able to read the Date_and_Time data as a single construct. Hope this helps, Daniel Chartier |

Now i have found the structure also for date and time, but don't forget to convert your bytes first in BCD format. You will find the system manual here Regards, Scorp |
