Thanks!

According to http://tmi.yokogawa.com/us/service-support/faqs/xviewer-fld-floating-data-format-information/
The floating point (FLD) format is very simple. No need for detailed explanation. The sampled data stored in the acquisition memory is converted using the specified range and saved to a file in 32-bit IEEE floating format. The data notation is little-endian (Intel format).
That is, the 32-bit (4-byte) acquisition data is formed in the order of channel (order). It consists of only the 32-bit (4-byte) data formation. Each acquisition data can be extracted by unit of 32-bit (4-byte). That is all
1. Press Ctrl+3 to open the Import Wizard
2. Select "Binary" as Data Type
3. Select the data file in Data Source
4. click "next" twice, there comes the "Import Wizard - Data Pattern"
5. The Pattern should be:
---------------------------------------------
Column Type Size Count
---------------------------------------------
1 Real 4 1
---------------------------------------------
6. Click "finish"
Now you have a worksheet of one column data. Say, the data have 2 channels, each channel 1024 points. You can split the one-column data to columns, in which each column represents one channel:
int nPoints = 1024;
int nChannels = 2;
range rr = col(1);
for(int i = 0; i < nChannels; i++)
{
range channel = col(A)[nPoints * i + 1 : nPoints * (i + 1)];
wcol(i+2) = channel;
}
