Introduction

Beremiz is free software toolkit for automation. It's conform with IEC61131 languages and can drive graphicaly your system.

Beremiz is divided in two softwares:

  • 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 throught network to its.

Then there are two triky things to do to use beremiz on APF* platforms :

  • Configure Beremiz.py to cross-compile binary for ARM
  • Run python program Beremiz_service.py on apf.

Installation

Host

Host part of beremiz is included under armadeus : 

make menuconfig

Then select : 

Package Selection for the target  --->
    Development tools  --->
        [*] matiec 
    ...
    Graphic libraries and applications (graphic/text)  --->
        [*] beremiz framework

Then : 

make

To launch beremiz type : 

python buildroot/output/build/host-beremiz-358db9d64aa1/Beremiz.py


To see how to install Beremiz on your host, please see the official website (How to build with Linux).

Target

APF28

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

install python 2.7

run 

make menuconfig

On up to date armadeus trunk view, then select : 

Package Selection for the target  --->
    Interpreter languages and scripting  --->
        [*] python
            python module format to install (.py sources only)  --->
                          (X) .py sources only

then make : 

$ make
Install Pyro3.14

Pyro 3.14 is included under armadeus distribution : 

make menuconfig

Package Selection for the target  --->
    Interpreter languages and scripting  --->
        external python modules  --->
            [*] python-pyro
Install Beremiz_service.py

Beremiz_service is included in Armadeus distribution (trunk) : 

Package Selection for the target  --->
    Graphic libraries and applications (graphic/text)  --->
        [*] Beremiz --->

Simple usage

Target connection

  • When Beremiz.py is launched on your Host, create or open a project then save it.
  • in project parameters add 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 transfert the program to target...
