In recent months, we have ported components of our COMPROTware:Library to SPARC computers running the Solaris 10 operating system for a customer. Our first experiences with Solaris date back many, many years, and we have had and continue to have projects on this platform.

Are you looking for knowledge and experience with SPARC computers and the Solaris 10 operating system (SunOS 5.10)? We can deliver!
If you have any questions or would like more details about COMPROTware:Library for Oracle Solaris 10 on SPARC, please contact us: e-mail cplb@realthoughts.de

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 ...

• 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.

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 ...
