[etherlab-users] DeviceNet EL6752, "Timeout after 1000 ms while waiting for SDO 0xf800:0 download response."

[Richard Hacker]

The first thing is to try to get the slave into OP somehow: do not set 
0xf800:0, as well as subindices 10,11!! I do not see the latter in the 
documentation!

Then:
Have you tried to get the device running without using 0xF800? As far as 
I can read from the documentation, it may be possible - the slave 
address can also be set in 0x8000:there. Maybe that works (although I am 
not a specialist in DeviceNet)
