Ethercat auto configurator. was created by Grotius
Hi Guys,

This file is a program for auto configuration for ethercat devices.

It don't need a .xml config file to setup your linuxcnc ethercat environment.

It uses a sligtly modified ethercat-master source code to retrieve a digital "$ ethercat xml".
And has a bug fix for inconsistent alias nr's.

This source code an be integrated to a linuxcnc component quite easely.
Therefore may be there are volunteers to do this.

As i tested this on the following bus configuration with succes, it's not tested to config servo's etc.
If i had a ethercat servo here, i would sure test it right away.

Example output :
Starting EtherCAT master 1.5.2  done
init example 0.
init ethercat start.
Print ethercat devices and retrieve device data vector.

Hi,

To create a program like twincat for linux i made a little example,
how we can do this.

Here  is a little project that show's the ethercat configuration.
It dynamicly add's button's, labels and checkboxes.

It includes reading and writing a few value types. But can be expanded
to read & write more ethercat data types.

This works nice.
 

I think we can also modify the linuxcnc-ethercat source to automate the .conf process.

Hi,

Maybe we can add a node configurator.

This then can be used to simulate the ethercat devices, by adding controls, like buttons, etc. for interaction.
And eventually it could be used as a plc controller, when adding logic just as classicladder.

It seems beckhoff has twincat for linux, running on debian. But it is not open source.
Did they write the ethercat master for linux themselfves?
They say in linux you can run multiple instances of twincat.
