The allocation of the data words from DW2 up to DW5 is only of significance for the sub-command
01h (= transfer time and date in BCD format to PLC).
For the sub-command 05h (= transfer time and date in ASCII format to the PLC) the string to be
transferred is filed in the data words DW2…DW11.
The following character string is, for example, transmitted: Fr 02.06.89 22:55:58
