Download the CPTT installation file cptt_01.46.exe (approx. 1540K) 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:
  

  • MS Windows 95/98/98SE/ME and NT4 is not supported anymore.
  • Directory and file names containing non-ASCII characters (like German ä, the Swedish å or the Frensh ç) are now handled correctly.
  • Protocol traffic monitoring at the serial or network interface of the ABB RTU560 with RIO Server (no extra CPRIOServer license required).
  • All Cleartext messages in a Message List are now associated with a certain protocol. If the selected Protocol Profile does not fit the protocol of the message then a warning is displayed and it is not possible to work with this message.
  • Support for installed WinPCap: If you have WinPCap installed on your computer then it is possible to use it for Network Monitoring.
    In Edit->General Preference you can control whether you want to use WinPCap or not. If you use WinPCap you will additionally receive the Ethernet Address and non-IP packets, like ARP packets.
  • ICMP-, IGMP- and ARP-Packets now shown: A TCP/IP stream or UDP/IP packets are not the only way two hosts communicate. They exchange a lot of information by other protocols like ICMP, IGMP and ARP. Because the three mentioned before give important information for a (not) running IEC 60870-5-104 or DNP over LAN/WAN connection these protocols are now shown in CPTT.
  • Handling of Serial PCMCIA Cards with large character buffer: Modern Serial PCMCIA Cards buffers much more received characters (e.g. 100 characters) before they forward the characters to the operating system. Standard PC hardware buffers just 16 characters. The result is a different timing. We adapted CPTT to this requirements to ensure optimal efficiency.
  • And many minor improvements ...
• GUI:
  
  • Menu item User Engine Class ... was moved from menu "Edit" to menu "Extra".
    Background: This item is rarely used. Therefore its formerly outstanding position in the "Edit" menu was not the adequate place for it.
  • Parameter Log Comm. Errors was moved from Protocol Profile to General Preferences.
    Background: This parameter is a general parameter used by all protocols (like "Log pure Link Layer Frames"). It fits to General Preferences better.
  • A LineMarker was introduced in the MessageView to ease the reading of long cleartext lines. The display of the LineMarker can be controlled in General Preferences.
  • Problem in Send message ... in the background menu corrected: The content of the message was lost on every restart of CPTT. Now after restarting CPTT the previously entered message is still available.
  • The default size for the Message Storage is now 300,000 entries (was 30,000 entries). The maximum size is now 10,000,000 entries.
  • In window Help->About now all implemented protocols and options are listed, non-licensed protocols and options are grayed-out.
  • And many minor improvements ...
• Transmission Protocols:
  
  • IEC 61850: New transmission protocol in CPTT. IEC 61850 is a standard for "Communication networks and systems in substations". It is closely related to IEC 60870-6, TASE.2 and UCA 2.0.
    We implemented monitoring of IEC 61850 connection (mapping to MMS/GOOSE).
  • MODBUS TCP/IP: New transmission protocol in CPTT. MODBUS TCP/IP is MODBUS serial adapted to network and TCP/IP transmission. The message format on application layer is unchanged, the lower layer is newely defined.
  • Landis&Gyr TG 809: New transmission protocol in CPTT. TG 809 is a general telecontrol protocol like IEC 60870-5-101.
  • Raw data Network: This protocol is new. By "Raw data Network" you can communicate over TCP/IP or UDP/IP with a communication partner. You can simulate a client or a server and send any character to your partner´s port no.
    The implementation of "Raw data Network" also includes Network Monitoring. Now you can capture the communication of any TCP/IP- or UDP/IP-based protocol and analyze its behaviour.
  • IEC 60870-5-101 unbalanced: Correction in the state engine regarding ACD handling.
  • IEC 60870-5-102: Correction in the state engine regarding ACD handling.
  • IEC 60870-5-103: Correction in the state engine regarding ACD handling.
  • IEC 60870-5-104 Ed. 2.0 partly incorporated:
    (1) Profile parameter "Auto STARTDT/STOPDT" controls whether STARTDT is automatically sent by the state engine after TCP connection establishment/the connection is automatically shutdown after STOPDT;
    (2) TESTFRact/con is sent even if data transfer is stopped;
    (3) The sequence numbers are not reset on STARTDT but on connection establishment;
    (4) F_SC_NB_1 is decoded;
    (5) All frames are acknowledged before Active Close;
    (6) Starting time of t2 changed.
  • DNP3: In "Edit message" Analog Output Block (obj.grp. 41) was not correctly handled. The value/status were interchanged.
  • DNP3: Decoding of Octet (Character) Strings Object (obj.grp. 110&111) implemented.
  • MODBUS serial and TCP/IP: Protocol stack for slave revised:
    (1) The sending of the Response to a Request is delayed so that the Response from a newely started Message List has reliably reached the state engine layer.
    (2) If there are several Responses in the sending queue then only the latest Response is sent, all others are discarded.
  • ABB RP570/571: Data Request Command RX is now supported.
  • ABB RP570/571: In "Edit message" the most significant bits of IDM/IDS got lost.
  • ABB SPA-Bus: Protocol stack for slave revised:
    (1) The sending of the Response to a Request is delayed so that the Response from a newely started Message List has reliably reached the state engine layer.
    (2) If there are several Responses in the sending queue then only the latest Response is sent, all others are discarded.
