Converting Trend History Files from Text to Binary

IWS provides the TXT2HST.EXE program to convert text files back into binary format.

To convert a file, use the following procedure:
  1. From a DOS window, change directory (cd) to the IWS \Bin directory:
    cd C:\Program Files\InduSoft Web Studio v7.0\Bin
    
  2. At the command prompt, copy the Txt2hst.exe into the same directory where the .txt file is located.
  3. At the command prompt, type Txt2hst.exe and specify the following parameters:
    • filename: Name of the ASCII file with history data to convert
    • [separator]: Data separator character (default is <TAB>)
    • [/e]: Extended functionality (data value with more than 10 characters)
    • [/i:HH:MM:SS]: Start time of data value in hours (HH), minutes (MM), and seconds (SS)
    • [/f:HH:MM:SS]: Finish time of data value in hours (HH), minutes (MM), and seconds (SS)

      For example:

      Txtt2hst.exe 02950201.txt
      

      The program creates a .hdr (header) file and converts the .txt file into a .hst binary file.

  4. After the program converts the file, type Exit to close the DOS window.
Note: You cannot create a math script for the TXT2HST.EXE program and use it in a Math worksheet to convert text files into binary format as you can for HST2TXT.EXE. The math script shortcut is available for binary files only.
