Beckhoff ethercat 64 with bit linuxcnc, How to install.

Hi,

you are able to create an config.xml for el6022, but this will give you only hardware control of the serial port (in/out buffer, status/control bits).

So you would have to implent the modbus communication layer by your own or you need an virtual com port driver which uses the halpins from the el6022 and could be used as "normal" com port for the linuxcnc modbus component. but this doesn't exists yet.

have anybody got any actual guide to install ethercat on lcnc nowdays please?

I really fighting with that installation, I managed to use several links and guides but without any success. every where something was wrong just one link from Grotius works just as OS installation and after run script to afterinstall the ethercat but it was just with "generic" drivers supported...
 

Hi Foxington.

I use this version after it was released:
sourceforge.net/projects/linux-11-pro/

It has a "skynet software installer" in the system menu. This will install additional software like lcnc, ethercat etc.

It uses this mirror:
github.com/grotius-cnc/Linux-Pro/releases/tag/1.0.0

If you look inside the deb package for pre-install or post-install files (scripts), you can see how it's installed.
github.com/grotius-cnc/Linux-Pro/release...inuxcnc-ethercat.deb

** works just as OS installation and after run script to afterinstall the ethercat but it was just with "generic" drivers supported...
If you are using iso's from grotius, check the crontab -e to change the generic driver in something else.

# In terminal : $ crontab -e
    @reboot echo MASTER0_DEVICE="$(cat /sys/class/net/enp0s25/address)" DEVICE_MODULES=generic > /etc/sysconfig/ethercat
    # Slow down the process so above line is done before the restart.
    @reboot /opt/ethercat/script/init.d/ethercat start
    @reboot /opt/ethercat/script/init.d/ethercat stop
    @reboot /opt/ethercat/script/init.d/ethercat restart
 

thanks for your time, your work is briliant with lcec and skynet too... I want to know small piece from you knowledges mr. ...

1. I will install linux from your hybrid iso...
2. after I hit install ethercat installer from desktop
3. then in terminal will run
there at the end of file I will add these few lines of code sure ? I have 8139too chipset such as " enp16s0 "
I am not soo good in linux yet just learning it in free time, I like to ask twice before I something mess out ... 
 

Hi Foxington,


1. I will install linux from your hybrid iso... => sourceforge.net/projects/linux-11-pro/fi...nux-Pro.iso/download
2. after I hit install ethercat installer from desktop => In the menu click on : skynet software installer

This will take a while.

3. then in terminal will run => # crontab -e     ( # is as superuser "sudo" , $ is user)

Crontab is just a tiny program that is active during pc startup. I used it to start up the ethercat bus. And it set's the mac adress
at boot time. Nothing can really go wrong here. If there is a fault it will pass without you notice it.

Lets tear this down :@reboot echo MASTER0_DEVICE="$(cat /sys/class/net/enp16s0/address)" DEVICE_MODULES=8139too > /etc/sysconfig/ethercat

A specific crontab command:
@reboot
This will give you the mac adress in return, you can also replace it with another command as long it returns the mac adres :
echo MASTER0_DEVICE="$(cat /sys/class/net/enp16s0/address)"
For example, you can write a tiny script:
echo MASTER0_DEVICE="$(givemymac.sh)"

Your driver, generic, or something else like :
DEVICE_MODULES=8139too

This ">" will overwrite everything at the destiny. ">>" is for append.
> /etc/sysconfig/ethercat

The reason i mentioned you the crontab -e. Is that if you want to change the generic driver in something else, you have to
know something is done at boot time.

Linux is the best. Stop using windows !

Yes thank you, I understand whats going on here.

I did it but issue is still same as was
but this nice script during booting linux will not solve problem of missing ethercat drivers like as " ec_8139too or other different ethercat network card drivers" which should not be used due their disabled during instalation of ethercat on linux...

but we are still solving " the consequence " of installation. But not " source " of problem I think soo. how to solve it for next ones who will want to install it theirself like as easiest as possible...  during the grotius installation are disabling every drivers just "generic" is used like "universal tool" which will work on everything but not with best performance if I am not wrong?

But I am still thinking about how to optimalize it:
1. check accessible network card and read actual value of used drivers.
2. this value should be compared of value of actual supported drivers for ethercat on linuxcnc
3. if there will be some driver which match with supported drivers it will be enabled and installed automatic
     else it will be installed " generic " driver, which will work with every network card...

should is it possible do you think?
