If you write call FB60, DB160, Hours - DB160.DBB3 Minutes - DB160.DBB4 Seconds - DB160.DBB5 Best regards. Hi. I have forgotten to warn, that data in a HEX-format. Excuse me. You use the instruction BTI for transfer HEX in INT. For an example L DB160.DBB3 T MW 218 L MW 218 BTI T MW 220 Hour in INT - MW220 Best regards.

The most important thing is you must put here - place in memory that you will be have cell in DATE_AND_TIME format. About the wizard i have something like that in my machine: //M(CLOCK/"My clock"//0,256,340,170//0,20) DEF CLOCK=(S///,,/WR1,FS2////30,135,90/6), DATE=(S///,,/WR1,FS2////160,135,150/6); ; DEF MIN_CLOCK=(I////WR0//"DB130.DBW48") ; HS1=("Clock",se3) HS2=("") HS3=("") HS4=("") HS5=("") HS6=("") HS7=("") HS8=("EXIT") ; VS1=("") VS2=("") VS3=("") VS4=("") VS5=("") VS6=("") VS7=("") VS8=("") ; LOAD CLOCK.VAL=RNP("DB130.DBW46")<<":" IF RNP("DB130.DBW48")<10 CLOCK.VAL=CLOCK.VAL<<"0" ENDIF CLOCK.VAL=CLOCK.VAL<<RNP("DB130.DBW48") DATE.VAL=RNP("DB130.DBW44")<<"." IF RNP("DB130.DBW42")<10 DATE.VAL=DATE.VAL<<"0" ENDIF DATE.VAL=DATE.VAL<<RNP("DB130.DBW42")<<"." DATE.VAL=DATE.VAL<<RNP("DB130.DBW40") END_LOAD ; CHANGE (MIN_CLOCK) CLOCK.VAL=RNP("DB130.DBW46")<<":" IF RNP("DB130.DBW48")<10 CLOCK.VAL=CLOCK.VAL<<"0" ENDIF CLOCK.VAL=CLOCK.VAL<<RNP("DB130.DBW48") DATE.VAL=RNP("DB130.DBW44")<<"." IF RNP("DB130.DBW42")<10 DATE.VAL=DATE.VAL<<"0" ENDIF DATE.VAL=DATE.VAL<<RNP("DB130.DBW42")<<"." DATE.VAL=DATE.VAL<<RNP("DB130.DBW40") END_CHANGE ; PRESS (HS2) LM("CLOCK") END_PRESS ; PRESS (HS8) EXIT END_PRESS ; //END More info about How to create wizard you find here. https://www.automation.siemens.com/doconweb/pdf/SINUMERIK_SIMODRIVE_04_2010_E/IAM.pdf?p=7#page=7&view=FitBH,0&pagemode=none I hope that I help Makaveli
