Hi David,
Communication slaves are very(!) difficult to handle, because they are
configured by means of SDO's. We are not aware of a free tool that can
be used to cofigure them.
They must be configured using TwinCAT(2). A trial version is available
free of charge from Beckhoff. This can be used to configure the slave.
Have a look at:
http://lists.etherlab.org/pipermail/etherlab-users/2012/001860.html
Search the mailing list for EL6731 or EL6751.

BTW: I cannot find EL6710! CANopen master is EL6751. And besides, -0010
is usually the slave and not the master! Check carefully what you have.
In case of a slave, select it in the TwinCAT Project, instead of the
master, before "Export configuration XML".

Hello,
I just trying to configure a CanOpen Network with a CanOpen Master
Module EL6710-0010 (Beckhoff), and get some doubts and issues.
I proceed just the module infosys website indicates, I did the next steps:
- Configure the BaudRate SDO:
# ./ethercat download -p4 -t uint8 0xF800 2 3 (250KBauds)
- Request a Detect Module Command
# ./ethercat download -p4 -t uint16 0xF002 1 0x11
-> At this step I need to write "something" to a octet_string[2]
entry, with this format the requested commando doesn work, I do it using
a uint16. Does someone know which octet is the expected?
- After the request command I observe the percent counter process:
# ./ethercat upload -p4 -t uint8 0xF002 2
0x80 128
# ./ethercat upload -p4 -t uint8 0xF002 2
0x95 149
- Until it keeps on value 0x01:
# ./ethercat upload -p4 -t uint8 0xF002 2
0x01 1
- It means, reading at infosys, that: "Command ended without error,
response data in SubIndex 3", then I tried read the octet_string[n]
directly from the terminal, but it can't be possible, then I do:
# ./ethercat upload -p4 -t octet_string 0xF002 3 > ~/prescan.out
- This output file is:
00000000 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
................

................
-> The first octet_couple correspond with the infosys website
detail, al the next is 0.
- I tried to repeat the request command but I get the next error:
# ./ethercat download -p4 -t octet_string 0xF002 1 0x22
SDO transfer aborted with code 0x08000021: Data cannot be transferred or
stored to the application because of local control
This is the point where i'm get stacked.
Is there some one that have some experience with this type of modules?
Thank you very much
Best regards
