Data count

(Number of data to read)

Sample time (sec)

(Sample time)

Specify block sample time

Input port

1. File Path

This input port specify file name to open for Read. It can be:

2. Seek Pos

Specify data read position of file.

4. Close

0 : Do not close file after read.

non-zero : Close file after read.

Output port

1. Status

0: Success, otherwise fail.

2. TotalSize

File size in bytes.

3. CurrentPos
