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 by 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

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.

• To install python 2.7 run :

make menuconfig

On up to date armadeus trunk view, then select :

    Interpreter languages and scripting  --->

         core python modules  --->
                    [*] bzip2 module
                    [*] bsddb module       
                    [*] codecscjk module   
                    [*] curses module      
                    [*] pyexpat            
                    [*] readline           
                    [*] ssl                
                    [*] unicodedata module 
                    [*] sqlite module      
                    [*] zlib module        
                    [*] hashlib module     

then make :

$ make

• To install Pyro3.14 the tricky method is:
  • download Pyro3.14 tarball here and decompress it in your nfs directory.

cd /local/export
wget https://pypi.python.org/packages/source/P/Pyro/Pyro-3.14.tar.gz#md5=2101230425e6c76f5aa2e9d5167cbd3b
tar -zxvf Pyro-3.14.tar.gz

• • Then once on your target (APF28) with python 2.7 installed go to your nfs directory and install it :

cd /mnt/nfs/Pyro3.14
python setup.py install
