  Beremiz is a framework for machine automation. It is meant to add PLC-like programing to embedded systems.

     7

     8

  Beremiz is [Free Software](https://en.wikipedia.org/wiki/Free_software), and conforms to

     9

  [IEC_61131](https://en.wikipedia.org/wiki/IEC_61131-3) and [PLCopen](https://plcopen.org/technical-activities/xml-exchange) among other standards.

    10

    11

  Beremiz supports all languages described in IEC_61131:

    12

  * Structured Text (ST)

    13

  * Instruction List (IL)

    14

  * Function Block Diagram (FBD)

    15

  * Sequencial Function Chart (SFC)

    16

  * Ladder Diagram (LD)

    17

    18

  IDE also includes tools to create Human-Machine Interfaces (HMI), and to connect your PLC programs to existing supervisions, databases, or fieldbuses:

    19

  * Modbus

    20

  * OPC-UA

    21

  * CANopen

    22

  * SVG HMI

    23

  * Wx HMI

    24

  * Python

    25

  * ...

    26

    27

  Runtime can be programmed remotely and allows variables tracing and forcing.

    47

    # rational:

    48

    #  - python plugin doesn't support python2 anymore on core20+

    49

    #  - attempts to get python2+pip+virtualenv in a core20 based snap failed
