Beremiz

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 
    ...
    Interpreter languages and scripting  --->
        ...
        [*] python
        external python modules  --->
            ...
            [*] python-pyro
    ...
    Graphic libraries and applications (graphic/text)  --->
        [*] beremiz runtime

• Build/install it:

$ make

• Then to launch it:

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

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 runtime

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...
