[etherlab-users] Using Ethercatmaster with Beckhoff EK1100, EL6731, EL6631, EL6752

[Carlos Herkt]

Hello,

i'm doing a  feasability study with Etherlab's Ethercatmaster.  As i'm
quite new to to this topic some questions arose. I'd be glad to find
some help here.

My hardware i'm using:
- EtherCAT Coupler EK1100
- Digital Output EL2002
- Digital Input EL1002
- DeviceNet Master EL6752
- ProfiNet Master EL6631
- ProfiBus Master EL6731

As slave i'm using an IPC with corresponding Profi*/DeviceNet - Slave
cards from Hilscher GmbH.

A PC has been setup with Ethercatmaster (Stable 1.5.2) on a Fedora
machine (3.15.7.x86_64).
(Later i'd like to convert to a BeagleBoneBlack or Raspberry Pi.)
Adapting the program in /~/ethercat-hg/examples/user/ i was happy to
achive some blinking on my EL2002.

What i'm trying to achive now is:
- First i'd like to establish a basic communication between
master<->slave (all LEDs green)
- On slave side i've got a program sending a heartbeatsignal to the
master (set bit 0 or 1).  I'd like to see that heartbeat for example
using /$ ./ethercat data /and in the next step let the DigitalII EL1002
blink to that heartbeat.

Is thi*s generally achieveable? Has someone experimented with
Ethercatmaster & EL6631?
*
I startet off analogically to this email:
http://lists.etherlab.org/pipermail/etherlab-users/2012/001862.html
Also I understand i have to enter my desired Inputs/Outputs via
/ec_pdo_entry_info_t/?
But do i need to somehow add the GSDML file of the slave to my porgram?
Like in TwinCat?

Are there any tutorials or example programs out there to
wrap my head around and if, could someone please point me there? Google
didn't dig up a lot to nothing.

Attached you'll find the xml file of the EL6631.

Any help, tips, links will be greatly appreciated! :)

With best regards,

Carlos Herkt
