[etherlab-users] Timeout while waiting for Sdo upload response

[Erwin Burgstaller]

Hi,

I'm now going to talk to a Beckhoff EL6001 device, which provides a serial interface:

http://www.beckhoff.com/english.asp?ethercat/el6001.htm

But there seems to be a problem with the sdo upload. I have this:

# ethercat slaves
0  0:0  PREOP  +  EK1100 EtherCAT-Koppler (2A E-Bus)
1  0:1  PREOP  +  EL6001 Schnittstelle (RS232)

Here are the log entries from starting the master with above configuration:

But listing the pdo entries works:

But:

# ethercat sdo
=== Slave 0 ===
=== Slave 1 ===
Sdo 0x1000, "Device Type"
Failed to get Sdo entry: Invalid argument

does not work.

Do I have to configure something elsewhere?


Best regards,
