Download the CPTT installation file cptt_01.44.exe (1410K) from [ site 1 ] or [ site 2 ].
(To nstall, start the self-extracting executable and save the MSI file in a temporary directory. Then double click the MSI file and follow the installation instructions.)

• General:
  • Export to file ...: In addition to the already implemented export to a textfile there are now three new exports:
    (1) Export to HTML file
    (2) Export to RTF file
    (3) Export to importable textfile
    With export to HTML file and export to RTF file the text decoration (font and color) is preserved so that you will see the same colors in the associated program.
    If the checkbox "Open the file in the associated program" is turned on then the newly generated file is automatically opened in Internet Explorer, Word or any other associated program.
    The new enhanced export functionality can be very useful in documenting the results of previously saved messge logging.
  • Import from/Export to Libpcap file: One more feature to exchange protocol messages with the world: Import and export IEC 60870-5-104 or DNP3 over LAN/WAN Ethernet frames/IP datagrams from and to programs like [ Ethereal ] or [ Packetyzer ]. Libpcap files contain network communication data. The file format goes back to [ tcpdump ] and is nowadays used as a standard format for exchange logged network communication.
  • Create Message List from Message Storage: For the protocols IEC 60870-5-102 and -103, DNP3, MODBUS (master direction), ABB RP57x and ABB SPA-Bus (master direction) this feature allows the user to create Message Lists based on the communication between master and slave. You can choose to create the Message List from the messages sent by the master or by the slave. The result is a new Message List with all the application layer messages from master or slave in cleartext (on a logical presentation level). After creation the Message List can be modified as any other Message List.
    The new Message List can be used to replay a certain situation captured in "real life" to test the behaviour of a master or a slave, or to collect all data points installed in a device. This feature is very helpful because it reduces the work necessary to setup large Message Lists.
  • New baudrate 115200Baud.
  • Monitoring GPRS/PPP communication: We added to CPTT the ability to monitor and interpret GPRS/PPP communication and filter IEC 60870-5-104 or DNP3 over LAN/WAN frames out of the data stream. Some of our customers noticed that the reliability of GPRS communication in some countries is very poor. To clarify whether communication problems between master and slave station are caused by the protocol stack or the transmission network it was necessary to monitor the GPRS/PPP data stream.
  • And many minor improvments ...
• GUI:
  • Message View Filtering: For all protocols the "Message Filter" window now contains the two buttons "Show all" and "Filter all". By this buttons the user can very easily change the basic state of all filters before setting/unsetting some certain items.
  • Find: A long awaited feature is now implemented: The search for text in the Message Storage.
    
    Open the "Find ..." window by pressing CTRL+F (or CTRL+F3 or in the background menu "Find ..."). You can search for any text. After ENTER the Message Storage is searched for this text. The text location appears highlighted.
  • A major new feature is the localization for Italian and French:
    In Edit->General Preferences ... you can choose "Italiano" or "Français":
    
    After restart of CPTT the user interface is running with the new Italian locale:
    
    Or with the new French locale:
    
  • Additional statistic items: Frames are counted; the current/average/maximum communication throughput is shown; time of the last bad character/frame, repeated frame and lost communication is reported; percentage of bad characters/frames and repeated frames are given.
    
  • And many minor improvements ...
• Transmission Protocols:
  • IEC 60870-5-101: Message View Filtering enhanced to filter by the Link Layer Address.
  • IEC 60870-5-101 & -104: Input of Structured Addresses when editing Message Lists or sending messages is now possible. A Structured Addresses is introduced by the '-character.
    
    
  • IEC 60870-5-103: Message View Filtering enhanced to filter by the Link Layer Address.
  • DNP3 & DNP3 over LAN/WAN: New protocol profile flag Auto.Respond Request introduced to control whether an automatic response to commands or an automatic empty response to requests should be sent.
  • DNP3 & DNP3 over LAN/WAN: Data Link Layer now supports the new broadcast addresses 0xfffe and 0xfffd and the self address 0xfffc.
  • DNP3 & DNP3 over LAN/WAN: The implementation of the Data Link Layer was revised to comply with the DNP3-2004 Certification Procedure Version 2.4.
  • DNP3 & DNP3 over LAN/WAN: When building a DNP3 message in the "Edit Message" window the Destination Address of the message can now be:
    - From the profile
    - Broadcast Address 0xffff
    - Broadcast Address 0xfffe
    - Broadcast Address 0xfffd
    - Self-Address 0xfffc
  • ABB RP570/571: Message View Filtering for (process) RTU address and different function codes implemented.
  • ABB SPA-Bus: Additional Message View Filtering for different message types implemented.
  • And many minor improvements ...
