Introduction

Beremiz is a Free Software toolkit for automation. It conforms with IEC61131 languages and can graphically drive your system.

Beremiz is divided in two software:

  • Beremiz.py: the graphical toolkit that run on the Host to drive the target,
  • Beremiz_service.py: the target runtime that execute the code compiled by Beremiz.py and sent to it through network.

There are two tricky things to do to use Beremiz on APF* platforms :

  • configure Beremiz.py to cross-compile binary for ARM,
  • run Beremiz_service.py on APF.

Installation

Host

Host part of Beremiz is installable through Armadeus Buildroot menuconfig : 

$ make menuconfig

Then select: 

Target packages  --->
    Development tools  --->
        [*] matiec 
    ...
    Graphic libraries and applications (graphic/text)  --->
        [*] beremiz framework
  • Build/install it:
$ make
  • Then to launch it:
$ python buildroot/output/host/opt/beremiz/Beremiz.py

Target

Python 2.7 and Pyro are required to run Beremiz_service.py: 

$ make menuconfig

Target packages  --->
    ...
    Interpreter languages and scripting  --->
        ...
        [*] python
        external python modules  --->
            ...
            [*] python-pyro
  • then:
$ make
Install Beremiz_service.py
$ make menuconfig

Target packages  --->
    ...
    Graphic libraries and applications (graphic/text)  --->
        ...
        [*] Beremiz runtime

Simple usage

Target connection

  • When Beremiz.py is launched on your Host, create or open a project then save it.
  • in project "Config" tab set the correct "URI_location":
URI_location: PYRO://192.168.0.33:3000

Replace 192.168.0.33 by the IP of your APF28.

  • then clic on «connect» icon.
  • You can compile your project and try to send it...
  • To configure your compiler, go to project configuration (double clic on head of hierarchy) and adding the path of your compiled armgcc :
YOUR_ARMADEUS_PATH/buildroot/output/host/usr/bin/arm-buildroot-linux-uclibcgnueabi-gcc

for linker and compiler.

  • You can then compile and transfer the program to the APF...
