[etherlab-users] Trouble with Beckhoff EL2252

Hello again,

I'm continuing my work on a proof of concept application using the IgH 
EtherCAT master however I'm having more problems.  Specifically I'm 
seeing warnings and errors when trying to setup a Beckhoff EL2252 module:
====================================================
Dec 15 08:49:31 lyot kernel: [90434.144520] EtherCAT ERROR 0-2: Slave 
does not support CoE!
Dec 15 08:49:31 lyot kernel: [90434.244602] EtherCAT ERROR 0-2: Failed 
to read number of mapped PDO entries.
Dec 15 08:49:31 lyot kernel: [90434.244605] EtherCAT WARNING 0-2: Failed 
to read PDO entries for PDO 0x1604.
====================================================
I see the above errors both when using my code (attached but not yet 
functioning) as well as using a working example program that I found on 
the mailing list [1] (much thanks Philippe).

WRT the warnings/errors above:
Do I need to be concerned about the errors/warnings that I see in the log?
If they aren't of concern is there any way to silence them?

Thanks in advance

To be or not to be, that is the question
                 2b || !2b
(0b10)*(0b1100010) || !(0b10)*(0b1100010)
         0b11000100 || !0b11000100
         0b11000100 ||  0b00111011
                0b11111111
255, that is the answer.
