1. Welcome

I am glad to announce you an important extension of the VFSM concept: the introduction of a complement control value which corresponds to a negation in boolean algebra. The technical note "Complement control values in VFSM concept" contains the details of this extension. We are very proud of this development which makes the specification easier to generate and more effective.

I would like to mention Mr. Vito Marolda here whose insistence convinced us eventually to extend our tools by that old but always postponed idea. Thank you, Vito.

I am sure that the user will appreciate this new possibility and become quickly familiar with that valuable feature. I have found it in my first project very useful indeed.

Regards
F. Wagner

2. Technical note "Complement control values in VFSM concept"

In a multi-valued control environment the use of the boolean NOT operator seems to be not very useful in expressions. An analysis presented in the technical note shows when and why we may use the complement operation which has a very similar function to the NOT operation. A description of the implementation in StateWORKS Studio rounds up the content of the note.

3. StateWORKS Studio version 7.0

In October 2007 we shall release the version 7.0 of StateWORKS Studio which contains several corrections and improvements. Of course it contains the implementation of the complement operation.

You may read and further develop old projects with the new version 7.0 of the Studio and you may run old specifications using the new RTDB run-time systems. The other way round does not work: you cannot read projects prepared with the new version with the old StateWORKS Studio and you cannot run specifications generated with the new StateWORKS Studio on old RTDB based run-time systems.

As the complement operation compensates to a large extent a creation of complex expressions for conditions in Master using Slave states we have abandoned this feature.

It is a major change. To avoid any confusion with older versions users who obtain the update will need to register again.

4. StateWORKS Studio LE

The LE version cannot be updated at this moment and it stays as it is. Thus, to benefit from the extensions you have to upgrade to BASIC or PRO versions.
