sorry, this was not meant to be disrespectful. So Gavin, if you felt offended,
please take my apologies. I was just trying to express that this was not meant

No, definitely not! Gavin is absolutely right. If an EtherCAT slave does

Dude, every defect gets respect! In Germany we have long time abandoned the

Subject: Re: [Etherlab-users] Estun EE-R0: Invalid input configuration
Ok, progress - kindof. After patching fsm_pdo.c to transferring the SDOs
enblock I now get:
[16864.527240] EtherCAT: Requesting master 0...
[16864.527247] EtherCAT: Successfully requested master 0.
[16864.527411] EtherCAT 0: Domain0: Logical address 0x, 16 byte,
expected working counter
An interesting difference I found is that the Acontis master does all
SDO-writing on block(like ecrt_slave_config_complete_sdo()), whereas Etherlab
does it in single transfers. I already realized that the Estun slave has
problems with this when mapping PDO entries. So I had already patched this

So I have written traces of the configuration phase and am digging in Wireshark
to spot the difference. For anybody who wants to join

What I have done is: start the slave connected to the Acontis master and let it
do the setup, then connect it (still powered up) to the Etherlab master and do
the cstruct command. The PDO mapping matches what I have setup in the Acontis
master.
Very good!

Indeed, that looks exactly the same.
One thing to note is that
$ ethercat cstruct
must be executed after a fresh power up of the slave and master
(ethercat restart), without ever having started a master application...
not that the slave simply returns its previous (maybe incorrect) setup.

Hm, I am still missing something. When I connect some Beckhoff devices they run
fine without any configuration at all:

Hi Dirk
How do you see that they are wrong? Sorry, still a noob...

refused state change (PREOP + ERROR).

Hi Richard,
Thanks for having a look at this.

How do you see that they are wrong? Sorry, still a noob...
Sorry about the ESI, it should be present in my link now.
Hi Dirk
You made a mistake configuring the TxPdo's. You need to read the docs,
and maybe the ESI (BTW I couldn't find it from your link)
What is your configuration?
$ ethercat config
Have you tried
$ ethercat cstruct
as a starting point?
Does the drive require distributed clocks?

I am trying to get a Estun EE-R00 IO-Module working. It works fine with an
Acontis EtherCAT master. After it has been operational on the Acontis master I
plug it to the Etherlab master. The PDO configurations looks allright:

SM0: PhysAddr 0x1000, DefaultSize
