E.TISSERANT "Beremiz Roadmap from CanFestival and MatPLC to"


The Beremiz PLC programming environment originally involved developers of the CanFestival free CANopen stack and MatPLC projects. The project has been initiated in order to fill the gap between free software and control engineering.

Today, thanks to Beremiz, automation users can easily connect IEC-61131 function blocks across CANopen networks with Free Software. Industrials, teachers, students and researchers use that GPL project, and actively contribute with new features every day.

But what about the PLC programs they produce? Could PLC programming also benefit from the Free Software ideology? A new Free Software Forge is to be held:

In this presentation, are presented project’s passed, present and future milestones.



L.BESSARD, M.SOUSA, E.TISSERANT "An Open Source IEC 61131-3 Integrated Development Environment"

A paper about Beremiz, going into some technical details on the compiler, and PLCopen editor.


The IEC 61131-3 standard defines a common framework for programming PLCs (Programmable Logic Controllers), which includes the complete definition of four programming languages and a state machine definition language. Industrial PLC vendors are slowly offering support for this standard, however small inconsistencies remain between their implementations, transferring programs between vendors is almost impossible due to different file formats, and licenses are generally too expensive to allow students do install these commercial solutions on their own computers.

To this end, the authors have developed an Integrated Development Environment (IDE) for the IEC 61131-3 framework, which is being offered to the general public under the GNU Public License (GPL). The IDE consists of a Graphical User Interface (GUI) and a backend compiler. Using the GUI the user may develop programs in any of the four programming languages, as well as the state machine definition language. The backend compiler is used to convert these programs into equivalent C++ programs which may later be compiled and executed on various platforms.

E.TISSERANT, L.BESSARD "Automated CanOpen PDO mapping of IEC 61131-3 Directly Represented Variables"


CiA DS-405 defines a way to publish variables of IEC 61131-3 programmables CANOpen nodes through their Object Dictionary, using Dynamic Index Assignment defined in DS-302. Correspondence between IEC 61131-3 variables and Object Dictionary entries is let to the responsibility of the PLC manufacturer.

IEC 61131-3 defines some Directly Represented Variables, specifying direction, size, and location of physical variables. In this representation, location is an arbitrary count of integers separated by dots. Again, correspondence between location of IEC 61131-3 and physical variables is manufacturer-specified.

As a consequence, and despite of the standardization efforts of PLCopen and CiA, there is still no real interchangeability of PLC nodes in a CANopen network. This paper proposes a method for the PLC application writer to explicitly publish and subscribe to CanOpen remote variables with Directly Represented Variables location. As a complement to DS-405, it could suppress most network reconfiguration steps when moving PLC programs from one brand to another.

Presented concepts and algorithms are already implemented in the Beremiz and CanFestival open source projects, and are publicly available.

Collected demonstrations

Open Software Platform for Automation (2012)

Under a government-funded project, SSLab and RTES lab are cooperating with mechanical industry to enable an open software platform for automation:

  • “Synchronous control drive for the multi axial drive and the high power servo-motor” project funded by MKE, Korea

  • PC-based automation system using EtherCAT, an industrial real-time Ethernet standard.

  • Open source software incl. Linux/Xenomai, Beremiz, and Etherlab EtherCAT master.

  • Comformance with international standard: IEC 61131-3, CiA302, CiA402, and IEC 61158.

  • HTML5-based vector-graphics human interface.

  • Wireless HMI

  • Incorporation of computer vision (OpenCV) in automation.


Video shows the demonstration of SmartCart, an electric cart that has been developed using Beremiz for performance evaluation. It is equipped with two Maxon drives controlled via CANopen interface. Users are able to steer the cart using gyro in his Android phone.

Free Software for Six Degrees Of Freedom motion (2009)

This video present a free software based machine made in collaboration with FESTO for LAAS.

LAAS is a French Scientific Research Lab involved in many scientific areas, mostly related computer and robotics.

For some computer vision experiments, this lab needed a positioning machine able to work within one cubic meter space with 6 degrees of freedom, and with 20ms time accuracy.

Motion control software had to be fully open so that researchers could have full control over positioning.

Realization involved six CANopen servo drives, and one industrial PC acting as a CANopen CNC, running real-time Linux, CanFestival and Beremiz.

As an input device for manual control mode, we used a wiimote.

The Open Source Coffee Machine (2008)

The Open Source Coffee Machine is a recycled coffee machine, controlled by a PC running Beremiz, and using some MicroMod CANopen I/O nodes from Peak-System. This machine have been prepared in collaboration with Peak-System for SCS-Paris-08 exhibition. It served Free coffees during 4 days on Peak-System’s booth and have been donated to IUT of Saint-Dié-des-Vosges so that students can have fun practising automation.
