GE 90-30/20/Micro manual Real INT, DINT, BCD-4, Word

4

—>REAL (INT, DINT, BCD-4, WORD)

The Convert to Real function is used to output the real value of the input data. The original data is not changed by this function.

When the function receives power flow, it performs the conversion, making the result available via output Q. The function passes power flow when power is received, unless the specified conversion would result in a value that is out of range.

It is possible for a loss of precision to occur when converting from DINT to REAL since the number of significant bits is reduced to 24.

Note

This function is only available on 350 and 360 series CPUs, Release 9 or later, or on all releases of CPU352.
