With COMPROTware:Testtool 1.50.8 today we published the last release of the 1.50-line. Starting with the next release we will introduce a new release numbering scheme:

<Release State>.<Major Release No.>.<Year 2 digits>.<Patchlevel>


  • <Release State> shows the state of the release:
    • "X" for a development snapshot.
    • "T" for a "Tested Release", which successfully passed all internal QA tests.
    • "A" for an "Approved Release", which successfully passed internal and external tests.
  • <Major Release No.> is increased on major technology changes.
  • <Year 2 digits> shows the last two digits of the year of release.
  • <Patchlevel> is increased for each published Tested and Approved Release.


For this release the news are:

  • For network-based protocols, for Client simulation, the IP address of a network interface can be specified as a hint to the operating system which IP address should be used ("bind to Client address").
  • IEC 60870-5-101/-104: IEC 60870-5-7- resp. IEC 62351-5-Message are now dissected.
  • MODBUS: Consecutive 16 bit-values are presented as 32 bit floating-point-value.
  • MODBUS: Function Code 23-Message (Read/Write Multiple Registers) can now comfortably be edited.

November 2017: COMPROTware:Testtool 1.50.6 with Message List Single Step

Since the last release in July, we together with some end users did very intensive development on COMPROTware:Testtool :

  • We are especially proud of Message List Single Step. With this the user can now send Link Layer Frames or Application Layer Message step by step to the opposite station.
  • For many protocols we introduced the new protocol profile parameter "Time offset", which is very useful to send a device under test into the past or into the future, without the necessity to change the computerĀ“s date&time.
  • L&G TG809 also did get a lot of improvements, e.g. qualified Message List like with IEC 60870-5-101/-104.
  • Data Object Database: We added extra data types for protocols with separate address spaces per data type. For the protocols IEC 60870-5-101/-104, DNP3 and L&G TG809 we introduced protocol-specific examples.
  • MS Windows 10 version 1709 (Fall Creators Update) is supported.

November 2015: CPTT T.1.49.25 with improved file I/O operations

In the early years of telecontrol protocols the emphasis of testing lied in the interoperability between different system and device suppliers. The focus has changed in the meantime towards reliability and integrity during 24/7-operation: Today, the interest is to find even the tiniest anomalies in the protocol communication.

For COMPROTware:Testtool this means that Message Log files (MLG files) are getting bigger and bigger, operations with giant data sets (files with several 100MB size) need to be performed more and more efficiently. Reason enough to improve all file operations considerably.

By putting Type Ident, Cause Of Transmission, Common Address, Information Object Address, ... into the Message ListĀ“s name you can react much more precisely on request messages.
