Explanation of function and operation
1. 32 bit operation (DEMOV and DEMOPV)
The contents (binary floating point data) of the transfer source [ +1, ] are transferred to [ +1, ].
A real number (E) can be directly specified as .
Program examples
1. In the program example shown below, a real number stored in D11 and D10 is transferred to D1
and D0 when X007 turns ON
2. In the program shown below, a real number "-1.23" is transferred to D11 and D10 when X007
turns ON
