According to wikipedia, Beremiz is the name of a fictitious mathematician, “Beremiz Samir, nicknamed The Man Who Counted” who “uses his abilities with calculation like a magic wand to amaze and entertain people, settle disputes, and find wise and just solutions to seemingly unsolvable problems”
The Beremiz Project is just free software for automation. Development started during summer 2005.

The IEC to ANSI-C compiler
Project started in 2002 by Mario de Sousa (UPorto)
Real compiler, same architecture as GCC
Compile ST/IL/SFC code into ANSIC code.

User code
The IEC to ANSI-C compiler
All POU parameters and variables are accessible through nested C structs
Located variables are declared as extern C variables

CanFestival CanOpen stack
Started in 2001 by Edouard TISSERANT
Meant to be compiled and run on any target, with or without OS, fully ANSIC
Provides GUI tools for network and node management
Import/export EDS files

CanFestival CanOpen stack
Beremiz project uses CanFestival as its preliminary IO library and HAL plugins
Other IO and HAL plugins willfollow
Target specific:CanFestival HAL
IO Lib:CanFestival
User code SoftPLC IEC std lib
[ debug / trace code ]

CanFestival CanOpen stack
The Network Topology Editor let Beremiz users declare Located Variables that directly map to CANOpen variables, with simple drag & drop
User only have to provide each node's EDS files

CanFestival CanOpen stack
CanFestival's virtual IO block GUI let user simulate and stimulate SoftPLC without any specific hardware

SVGUI : The SVG based HMI toolkit
INKSCAPE(drawing program)
HMI
© LOLITECH – TBI sarl
SVGUI : The SVG based HMI toolkit
SVGUI let user “draw” and “skin” GUIs
SVGUI is part of wxSVG, a free C++ SVG renderer
wxSVG project started in 2005 by Alex THUERING, Laurent BESSARD and Edouard TISSERANT
wxSVG data model is generated according W3C specifications (Official SVG's DTD and IDL files)
wxSVG relies on wxWidgets, which already runs many platforms
© LOLITECH – TBI sarl
SVGUI : The SVG based HMI toolkit
Edit with INKSCAPE(SVG based drawing program, OpenSource and multi-platform)
Edit with DefEditor(comes with SVGUI)
© LOLITECH – TBI sarl
SVGUI : The SVG based HMI toolkit
PLCOpen programs can access directly SVGUI widgets variables. HMI can then be programmed with no code at all.

SVGUI's .def editor (PLCOpen mode)

Current project status
PLCOpenEditor ready for beta release
IEC611313 to C compiler works, but C implementation of standard IEC library is still being written
SVGUI's DEFEditor and CanFestival's Network Topology Editor being integrated with PLCOpenEditor
Public project disclosure, web site, community tools and overall documentation have to be done.
Beta release planned for summer 2007

What next ?
Thanks to PLCOPen, Beremiz brings automation to everyone's use
Control engineer, researchers and hobbyists will share automation the same way free software community shares source code. Public repositories will appear
Teachers will use Beremiz, thus promoting open standards like PLCOpen, IEC61131, CanOpen, SVG ...
Automation “vendor lockin” will be a user choice

Behind the project
Lolitech is a French company, held in December 2005
Our business model is based on Free Software
Our goal is to bring Free Software to Industry
We will provide early commercial support for the project, and manage community contributions
Once autonomous, a community driven foundation will represent the Beremiz project.
