[?]: Set Date and Time in S7-312C using SFC0

[waard]

Hi, i want to set date and time in PLC using touch panel TP170A. I try to do this with next method:
1 I write in PLC's DB9 date and time using INPUT FIELD (TP170a) and variable of type DT, that's OK
2 i try to use that 8 bytes in DB9 from DBB28 to set plc's time with SFC0 like this:

Code: Select all

      L     W#16#1002                     
      T     LW     0
      L     8                         // 8 bytes   
      T     LW     2
      L     9                          // db9 
      T     LW     4
      L     28                         //from dbb28  
      SLD   3
      OD    DW#16#84000000
      T     LD     6

      CALL  "SET_CLK"
       PDT    :=#DaT               // DaT - TEMP - type: Date and time; Address - 0
       RET_VAL:=#ret              // ret TEMP - INT, address - 2.0 

And that's not working....
Maybe someone know what the problem here, thanks
