FL2REGL
Extracts the bottom 16-bit values of a 32-bit floating-point number.
FL2REGL 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 FL2REGL function:
Parameter | Data Type | Description | ||
|---|---|---|---|---|
Val | REAL | 32-bit floating-point REAL value. | ||
Q | DINT | Integer value representing the bottom 16-bits of
the 32-bit floating point number. | ||
TIP:
FL2REGL does not convert floats to integers.
Numbers remain in floating point format. To convert the input value to an integer, use the
ANA operator.
