  • About beremiz

    Free software for Automation

    Beremiz is an integrated development environment for machine automation. It is Free Software, conforming to IEC-61131 among other standards.

    It relies on open standards to be independent of the targeted device, and let you turn any processor into a PLC. Beremiz includes tools to create HMI, and to connect your PLC programs to existing supervisions, databases, or fieldbuses.

    With Beremiz, you conform to standards, avoid vendor lock, and contribute to the better future of Automation.

    Motivations

    Despite of open standards such as IEC 61131, PLCOpen and CanOpen, control engineers cannot deploy results of their engineering effort in an heterogeneous environment. It is usually required to rewrite your PLC program for each particular PLC brand.

    The reason for this is that proprietary solutions providers do not fully conform to standards, thus preventing interoperability, harmful to their business model.

    Furthermore, standards specification are necessarily non exhaustive and leave some "manufacturer specific" freedom to the implementer. Solution providers make great benefits out of those manufacturer specific details, at the expense of the freedom of the end user.

    The Beremiz Project fills the gap between those independent standards specifications, by providing an integrated reference implementation of them.

    Community and Support

    Community mailing list

    This moderated mailing list is the main community communication channel. For posting it's required to be subscribed to the mailing list.

    Searchable webarchive of the mailing list is available here.

    IRC

    Chat with developers on #beremiz channel on freenode.net

    Some tips for people who never used IRC before:

  • Note that IRC doesn't support history.
  • If you log out, you'll not get developer's answer tomorrow.
  • If someone is in chat, it doesn't mean he is online.
  • Developers may be away from keyboard, busy or work in different time zone than you.
  • Don't expect to get answer immediately, especially on weekend.
  • Ask question and keep running your IRC client until you get answer. If you don't want to keep running your IRC for at least 24 hours, just ask your question on community mailing list.

    Official Beremiz bugtracker is https://bitbucket.org/automforge/beremiz/issues.

    If you've found (reproducable) bug, and want it to be fixed. First search bugtracker, maybe someone already reported this issue. If the issue is already described, you may add your examples or comments to it.

    If the problem isn't described yet, then please check whether it exists in the latest version of Beremiz from development repository. If it still exists, then create new bug report for it.

    Perfect bug report contains:

  • Exact steps to reproduce the problem, to make it easier for developers to fix it.
  • Generated by Beremiz bug-report with backtrace, if it exists.
  • Beremiz PLC project used to reproduce the issue.
  • Screenshorts/screencasts for better understanding of the problem.
  • Bugs in matiec should be reported here.

    Improve translation

    The easiest way for newcomers to help Beremiz project without python knowledge is to improve support of your native language in Beremiz IDE.

    Beremiz developers use Transifex, web-platform for translations. https://www.transifex.com/beremiz/beremiz-ide. It is easy to use and is used by many other open source projects: dpkg, Mercurial, Bitbucket, Fedora, XFCE, PulseAudio, Django and many others. If your language is missing, request it on Transifex. It'll be added ASAP.

    Current status of translation.

    Update community wiki

    Beremiz community wiki is here. You are welcome to add/update information there.

    Improve documentation

    Another way to help the project is to improve current state of documentation. For example, you can improve description of functional blocks stored in plcopen/Standard_Functional_Blocks.xml and Additional_Function_Blocks.xml.
