If the cstruct info below looks like what you expect then it is possibly a problem with the setup (ie the calls to ecrt_master_slave_config(), ecrt_slave_config_pdos() etc aren’t matching correctly). It might also be that it requires some extra sdo settings on top of the standard ones.
When the ERROR state is set it should also set the reason in the Alarm Status Code register (register 0x134). use the command: ethercat reg_read -p0 -tuint16 0x134 Then refer to the following page to figure out what the code means: http://infosys.beckhoff.com/english.php?content=../content/1033/em37xx/1037010571.html&id=10272 or http://infosys.beckhoff.com/english.php?content=../content/1033/el6201/html/bt_ec_ethercat_al_statuscodes.htm&id If you have another computer with windows you could install TwinCAT on it and see what TwinCAT’s configuration is to connect to it.

If it is a Beckhoff CXxxxx computer via the EBus module it will need the CCAT (or similar) network card driver. However, it sounds like your Linux master is not a CXxxxx computer and you already have the EtherCAT networking running. I have not used the CX8010 so can’t offer too much advice but from what I understand it ring fences all of the IO on its EBus with its own logic to control it. You then have to choose what IO (or interface) you want to expose via its slave interface that the Linux EtherCAT master will access. What does the ethercat cstruct command return? Regards, Graeme.

What do you mean by slave CPU? Are you referring to the CX2100 module? What version of the master are you using? There is a CCAT driver written by Patrick Bruenn in the “stable-1.5” branch, but it is not in the “default” branch. Are you using this? If not, to use it you will need to build it with the master with the ENABLE_CCAT config flag (I think). I don’t use this driver as I wrote my own before it was available but I assume you use it in the same fashion as any of the other network card drivers, where you load the network driver modules you want to load (eg with modprobe). If you load the CCAT module first then the master should use it by preference (when you use the generic MAC address of FF:FF:FF:FF:FF:FF) rather than needing to specify a fixed MAC address. If you are not using the CCAT driver above, are you writing your own? I have attached a patch for the driver I use. It is written for EtherCat master revision 2526 (stable-1.5) and Linux Kernel 2.6.32. It may be useful as a reference. Regards, Graeme.
