Dear Reader,

after a lot of trail, and more error i came to the following problem:

in SCL it is possible to do an indirect addressing of a byte in a db with the following code:

QB[OutByte] := WORD_TO_BLOCK_DB(wDB_number).DB[ReadByte];
where in this case i write a byte to an output address. this works just fine.

now the problem is that this does NOT work for a Double word:

WORD_TO_BLOCK_DB(wDB_number).dbd[4]:= DINT_TO_DWORD(TIME_TO_DINT(RetTime));
here i try to write a time retrieved from sfc64 to a double word adress in the DB.

now the weirdest part is that itDOES work if i address the db directly:

db300.dbD[4] := DINT_TO_DWORD(TIME_TO_DINT(RetTime));

or the dbd directly:
WORD_TO_BLOCK_DB(wDB_number).dbd4:= DINT_TO_DWORD(TIME_TO_DINT(RetTime));

What can i do to address the BOTH indirectly?? without having to do a bytewise copy..

Regards,

Rene
