Welcome to our website ...

The first COMPROTware:Testtool release this year is published and new is

• Each Message in the Message Storage now has a Message Tag, a value between 0 and 255 that can be filtered. At the moment, Message Tag values are assigned after analysis while network monitoring, each TCP/IP connection receives its own Message Tag value.
• The communication between RIO Client and RIO Server is expanded, among other things the known media/locations of the RIO Server are transmitted to the RIO Client.

• We have made some corrections to ABB SPA-Bus.
• Many minor improvements ...

New with this COMPROTware:Testtool release:

• CPTT 2.23.3 is adapted to and successfully tested with MS Windows 11 version 23H2.
• We added the protocol IEC 62056-21 (formerly known as IEC 61107) for meter reading transmission, tariff and load control to CPTT.

• CPTT runs on Linux with 64 bit distributions of Java 21, Java 17, Java 11 and Java 8.
• Many minor improvements ...

New with this COMPROTware:Testtool release:

• Various extensions around TLS-secured TCP/IP connections and PKCS#12 files.
• CPTT runs on 32 bit distributions of Java 17, Java 11 and Java 8.
• MODBUS Function code 43 - Encapsulated Interface Transport mit MEI 14 - Read Device Identification is now dissected.

• When dissecting MODBUS Messages, significantly more checks for valid no. of points, resulting end addresses, and much more implemented.
• Many minor improvements ...

At the end of the year we published another new COMPROTware:Testtool release. Main focus: TLS-secured TCP/IP connections according to IEC 62351-3.

• The input and validation of PKCS#12 files has been completely revised. PKCS#12 files with certificate chains are now processed correctly.
• The demo certificates for TLS-secured TCP/IP connections have been replaced: we now deliver 2 sets of certificates. The two documents Short introduction to TLS/ceritificates as PDF (approx. 120K) and Example with two certificate sets as PDF (approx. 90K) provide a brief introduction to TLS and describe the use of the demo certificates.
• Unfortunately, we had some issues with the CPTT 2.22.4 adaption to MS Windows 10 version 22H2 and MS Windows 11 version 22H2, which have been fixed in this release.

• In addition, there are extensions and corrections for MODBUS: Both big and little endian byte order for 16-bit values are supported. Issues have been fixed when processing MODBUS messages, specifically with Responses with Function code 5 (Write single coil) and 6 (Write single register).
• Many minor improvements ...

New with this COMPROTware:Testtool release:

• CPTT 2.22.4 is adapted to and successfully tested with MS Windows 10 version 22H2 and with MS Windows 11 version 22H2.
• If, during a slave simulation, no frames for the simulated station are received in the first few seconds but only frames for other stations, a warning is now issued which refers to the other, the simulated station number.

• Many minor improvements ...

For release 2.22.3, we continued the developments we started in the last COMPROTware:Testtool COMPROTware:Testtool release:

• In the Protocol profile windows, all settings for which a tool tip description is available are additonally marked by a circled small i.
• An error encountered during initialization of network monitoring or enumeration of network adapters is now reported in the Protocol profile window.

• With many MODBUS serial and MODBUS TCP/IP Messages, the 16-bit values are now also displayed as binary values.
• Many minor improvements ...

We start in this year with a lot of new things!

The major developments in COMPROTware:Testtool release 2.22.2 are:

• In all Protocol Profile windows and all Message View Filter windows, the input field values are now checked immediately and if necessary a warning or error description is shown directly under the input field.
• For all network-based protocols after network monitoring or after libpcap file import, we now present a bunch of statistic values. The received network packets are analyzed and summarized: Statistcs per IP address for sent/received Ethernet frames, sent/received Payload bytes and Payload min/max length are shown. Also per client/server partners the first/last frame date and time, duration, number of sent/received Ethernet frames, sent/received Payload bytes, Payload min/max length are shown.

• For MODBUS TCP/IP, Master simulation we introduced the Protocol Profile parameter "NumberMaxOfClientTransaction" and changed the Master implementation to comply with the protocol standard.
• Many minor improvements ...

At the end of the year we published another COMPROTware:Testtool release with minor corrections:

• CPTT 2.21.6 is adapted to and successfully tested with MS Windows 10 version 21H2 (November 2021 update).
• Also, CPTT 2.21.6 is adapted to and tested with the updated Java distributions [ Eclipse Adoptium Temurin JRE 8, 32 Bit ] and Oracle Java 8u311.

• For all manually changed IEC 60870-5-103-Messages descr.text, VSQ is now correctly set to 0x81 again.
• Many minor improvements ...

• CPTT 2.21.5 is adapted to and successfully tested with MS Windows 11 version 21H2.
• The parallel installation of Wireshark 3 and newer (with Npcap) is now supported. Npcap is used by CPTT for network monitoring if available. Important: Before Wireshark 3 is installed, it is strictly recommend to unstall WinPcap.

• The new Java distribution of the Eclipse Foundation named Adoptium Temurin JRE 8, 32 bit is supported as a further and probably soon the leading Java runtime environment.
• Many minor improvements ...

For the release series 2.21 for the year 2021 we now published COMPROTware:Testtool 2.21.1.

Standing out with CPTT 2.21.1: At the beginning of a line a orange marker indicates a warning and a red marker indicates an error. For an error the descriptive text is always shown. For a warning the descriptive text is shown if in Formatting Options the corresponding toggle switch is on.

More changes:

• At start resp. end of simulation or monitoring, the protocol profile, statistics etc are shown with Formatting Option "Brief" with limited and with Formatting Option "Full" in full detail.

• CPTT now is a RIO-Server, too: Without protocol license and without dongle now the in CPTT integrated RIO-Server can be turn on and can be controlled by a remote CPTT.
• Serial line receiving improved in case of fast, en masse stream of (unexpected non-Frame) characters and of bad parity/bad framing chars.
• Many minor improvements ...
