Dear Andrey:

I'm learning on BeremizIDE and beremiz-service usage.

I grabbed all the information available at Beremiz site, and the Smarteh manual too.

However, I cann't found any clear information about running Beremiz as a virtualPLC on Linux (runtime?).

Is that the beremiz-service that http://beremiz.readthedocs.io/en/latest/manual/connectors.html refers to?

Or virtualPLC runtime for Linux is not available under Beremiz project?

Meanwhile, I've decided to try, perhaps doing brute force intents ;-)

For this, I've wrote a very simple test program (two digital inputs, one digital output, and one RS block).

BeremizIDE succefully compiles this program and generates.st files, too.

I've declared BeremizRoot URI_location as LOCAL:// in Project > Config and launched beremiz-service from terminal:

[daniel@hardwork ~]$ beremiz-service

/usr/lib/python2.7/site-packages/wx-3.0-gtk3/wx/_core.py:16629: UserWarning: wxPython/wxWidgets release number mismatch

  warnings.warn("wxPython/wxWidgets release number mismatch")

HTTP interface port : 8009

Pyro port : 3000

Current working directory : /home/daniel

UI thread started successfully.

Then, I have connected BeremizIDE to virtual PLC and transferred the generated program.

But Beremiz PLC Log complains about various errors, showed in terminal, too:

<code>

PLCobject : Traceback (most recent call last):

  File "/usr/share/beremiz/runtime/PLCObject.py", line 269, in _LoadPLC

    self._PLClibraryHandle = dlopen(self._GetLibFileName())

OSError: /home/daniel/d792bf5ec10db55c9fdfe5e7071c5b64.so: undefined symbol: __IX0_1

</code>

Undefined symbol: __IX0_1 ????

But I've declared all input-output variables in my program in IEC 61131-3 style: %IX0.0 , %IX0.1 , %QX0.0 !!!

I'm not able either to start or stop virtual PLC from Beremiz task icon contextual menu; http://localhost:8009/ shows PLC IS STOPPED all the time.

I cann't found where the errors are originated.

I send you, under my signature, all the logs in PLC Log (including live Python shell), and terminal messages too.

NOTE: files attached to my original email aren't accepted by list.sourceforge.net service.

Could you kindly look at these, and tell me what I'm doing wrong?

Or perhaps virtualPLC is a misconcept from me?

Referred to our previous conversation, on Beremiz and Modbus:

If I can run any kind of virtualPLC on Linux, first I will try to do remote control onto a Siemens LOGO! v8, that has Modbus TCP enabled.

If I can grab some Modbus RTU module from my friends, I will test if is possible to remote control them via RS-485 bus (I have USB/RS-485 adapters, CH340 and Prolific 2303 based).

Off topic?

I'm hardily testing OpenPLC Project runtime for Linux, too ( http://www.openplcproject.com/getting-started-linux ).

I've succesfully managed to install it in Arch Linux, and I'm using BeremizIDE to generate the program and export to a .st file required by this runtime.

The only previous action I need to upload the program to OpenPLC runtime, is to change CONFIGURATION config to CONFIGURATION Config0 in generated_plc.st file.

A little question: is possible to edit this configuration name directly in BeremizIDE?

Soon, I will try to run OpenPLC Project runtime in Raspberry Pi, but on Arch Linux ARM, not on Raspbian.

I wish to use cheap WELLPRO Modbus RTU interfaces in the future (see http://www.shwellpro.com/products.asp ).

Unfortunately, in OpenPLC v3 there is not a Modbus slave driver available yet  :-(

Your answers will be welcome!

Best regards.

 Hi Daniel,

 I am really pressed for time today, but I can just quickly let you know that
when you map variables to a specific location (%Q0.5.3, ...), then that
location must have been defined by adding, for example, a communication plug-in
(CANfestival, Modbus, ...).
 Beremiz has no way of guessing how to map that location to a specific hardware
address.

 I suggest, for a first attempt,  you try to run your code without mapping any
variables to locations.


   Mario.

Beremiz repo contains bunch of examples:
https://bitbucket.org/automforge/beremiz/src/tip/tests/?at=default

Most of them are shown on Beremiz YouTube channel:

Dear Mario and Andrey:

First, my apologizes for my delayed response.

I'm working very hard these days (yesterday 12 hours continuously), an I had no time to carefully read and implement your helpful tips.

The only task on Beremiz that I have done is to remove the mapped I/O variables assignement, and relaunching Beremiz_service.py all seem worked fine.

Thanks you, very much!!!

I will spend more time learning about Beremiz this weekend; soon I will send you an email with my first results.

I have a lot of questions to resolve, is there a Beremiz users mail list?

I don't want to generate "noise" in your developers list...

BTW: some examples may be hard to understand for me, I will try (perhaps Youtube examples will help me) ...

@andrey

>BTW, does Arch have arm cross-toolchain available (arm-none-linux-gnueabi-gcc)?

Yes, of course.

See https://www.archlinux.org/packages/community/x86_64/arm-none-eabi-gcc/ 

Best regards,

No problem. As you see, there is no much noise here at all. :-)

And there is no beremiz user mailing list so far.
