[etherlab-users] Initializing CanOpen Master Module EL6751-0010

[Richard Hacker]

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".
