Despite of open standards such as IEC 61131, PLCOpen and CanOpen, control engineers cannot easily transfer programs between vendor solutions.
Open Source for Open Standards
To this end, the Beremiz Project produce Free and Open Source software for automation :
Integrated Development Environment
Embedded runtime software
Automation, control and HMI software

2. The IEC to ANSI-C compiler
Project started in 2002 by Mario de Sousa (UPorto)
Compiles ST/IL/SFC code into ANSIC code.

3. CanFestival CanOpen stack
Started in 2001 by Edouard TISSERANT
Runs on any target, with or without OS, fully ANSIC
For Beremiz, CanFestival provides :
A point & click GUI for CANOpen I/O
An I/O library
A HAL library
Target specific:CanFestival
IO Lib:CanFestival
User code SoftPLC IEC std lib

3. CanFestival CanOpen stack
Network Topology Editor maps CANOpen process variables to IEC Located Variables with simple drag & drop
User just provides vendor EDS file for each node

What next ?
Thanks to Open Standards, Beremiz will bring 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
Beremiz will be used for teaching, implying long term adoption of PLCOpen, IEC61131, CanOpen and SVG.
Automation “vendor lockin” will be a user choice

Current project status
On the road to stability :
PLCOpenEditor , IEC to C and SVGUI's are experimental, they prove the concept, but need improvements
2.5 manyears needed to provide a production release
Time to join and contribute :
Source is available on public CVS
Sponsoring, donation, patronage or funding are needed
Shared automation repositories need your blocks

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