REG2FL
Combines the top and bottom 16-bit values of two integers to produce a
32-bit floating point number. REG2FL enables sending float numbers over Modbus as a pair of
16-bit word values. The Modbus protocol does not support floats.
Parameter values for the REG2FL function:
Parameter | Data Type | Description | ||
|---|---|---|---|---|
High | DINT | Top 16-bits of the float value | ||
Low | DINT | Bottom 16-bits of the float value | ||
Q | REAL | Float value by combining the two 16-bit
values. | ||
TIP:
REG2FL does not convert integers to floats.
Numbers are still in floating point format. To convert the integer value to a float, use the
REAL operator.
