Hi,
create your own function:
******
FUNCTION IEEE754_To_Real : REAL
VAR_INPUT
Word0:WORD; (* Low Word bit 0-->15*)
Word1:WORD; (* High Word bit 16-->31*)
END_VAR
VAR
dword1:DWORD;
pR: POINTER TO REAL;
END_VAR
******
dword1:=Word1*16#10000+Word0;
pR:=ADR(dword1);
IEEE754_To_Real:=pR^;
******

Moti.
