[etherlab-users] Failed to read reg alias of slave (plain text)

[Len Remmerswaal]

Hi all,

I am trying the etherlab master, and I am getting the following message 
when attaching a small ethercat segment and starting the Etherlab master 
(v. 651e9cfb244b).

EtherCAT DEBUG: Reading alias from register 0x0012 of slave 5.
EtherCAT WARNING: Failed to read reg alias of slave 5.

When running "ethercat slaves --v" I get this amongst others (question 
marks inserted by me):

When running a few reg_read commands I get this:

# reg_read -p5 0x0012 2
Failed to read register: Input/output error
# reg_read -p5 0x0010 4
00000000 06 00 00 00 |....|
# reg_read -p5 0x0000 32
00000000 01 01 0c 00 02 04 04 00 00 00 00 00 00 00 00 00 |................|
00000010 06 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................|

The 00 at addresses 0x0007 and 0x0008 seem to be wrong and responsible 
for the weird port descriptions,

All other slaves seem to be doing fine.
I may be linking things that I should not see as linked: I am new at 
this stuff. However, can anybody point me at a probable cause? I sure 
would love that DC on my slave!

Thanks,
Len.
