# Beremiz #

     4

     5

Beremiz is an integrated development environment for machine automation. It is Free Software, conforming to IEC-61131 among other standards.

     6

     7

It relies on open standards to be independent of the targeted device, and let you turn any processor into a PLC. Beremiz includes tools to create HMI, and to connect your PLC programs to existing supervisions, databases, or fieldbuses.

     8

     9

With Beremiz, you conform to standards, avoid vendor lock, and contribute to the better future of Automation. 

    10

    11

Beremiz consists of two components:

    12

    13

* Integrated Development Environment (IDE), [Beremiz.py](https://bitbucket.org/automforge/beremiz/src/tip/Beremiz.py?at=default). It's running on user's computer and is used to write/compile/debug PLC programs and control PLC runtime.

    14

* Reference runtime implementation in python, [Beremiz_service.py](https://bitbucket.org/automforge/beremiz/src/tip/Beremiz_service.py?at=default). It's running on target platform, communicates with I/O and executes PLC program.

    42

		autoreconf -i

    43

		./configure

    44

		make

    45

    46

* Build CanFestival (optional)  

    47

  Only needed for CANopen support. Please read CanFestival manual to choose CAN interface other than 'virtual'.

    48

    49

		cd ~/Beremiz

    50

		hg clone http://dev.automforge.net/CanFestival-3

    51

		cd ~/Beremiz/CanFestival-3

    52

		./configure --can=virtual

    53

		make

    54

    55

* Build Modbus library (optional)

    56

  Only needed for Modbus support.

    57

    58

		cd ~/Beremiz

    59

		hg clone https://bitbucket.org/mjsousa/modbus Modbus

    60

		cd ~/Beremiz/Modbus

    61

		make

    62

    63

* Build BACnet (optional)

    64

  Only needed for BACnet support.

    65

    66

		cd ~/Beremiz

    67

		svn checkout https://svn.code.sf.net/p/bacnet/code/trunk/bacnet-stack/ BACnet

    68

		cd BACnet

    69

		make MAKE_DEFINE='-fPIC' all

    70

    71

* Launch Beremiz IDE

    72

    73

		cd ~/Beremiz/beremiz

    74

		python Beremiz.py

    75

    76

## Run standalone Beremiz runtime ##

    77

    78

Runtime implementation can be different on different platforms.

    79

For example, PLC used Cortex-M most likely would have C-based runtime. Beremiz project contains reference implementation in python, that can be easily run on GNU/Linux, Windows and Mac OS X.

    80

This section will describe how to run it.

    81

    82

If project's URL is 'LOCAL://', then IDE launches temprorary instance of Beremiz python runtime (Beremiz_service.py) localy as user tries to connect to PLC. This allows to debug programs localy without PLC.

    83

    84

If you want to run Beremiz_service.py as standalone service, then follow these instructions:

    85

    86

* Start standalone Beremiz service

    87

    88

		cd ~/Beremiz

    89

		mkdir beremiz_workdir

    90

		cd ~/beremiz

    91

		python Beremiz_service.py -p 61194 -i localhost -x 0 -a 1 ~/Beremiz/beremiz_workdir

    92

    93

* Launch Beremiz IDE

    94

    95

		cd ~/Beremiz/beremiz

    96

		python Beremiz.py

    97

    98

* Open/Create PLC project in Beremiz IDE.  

    99

  Enter target location URI in project's settings (project->Config->BeremizRoot/URI_location) pointed to your running Beremiz service (For example, PYRO://127.0.0.1:61194).

   100

  Save project and connect to running Beremiz service.

   101

   102
