Most likely, there is something invalid in the parameters for the SDO configuration functions. Youll need to post all of the related code if you want help in locating it.
From: etherlab-users [mailto:etherlab-users-boun...@etherlab.org] On Behalf Of David Jiménez Mejías Sent: Thursday, 29 October 2015 23:53 To: h...@igh-essen.com; etherlab-users@etherlab.org Subject: [etherlab-users] Beckhoff 6731-0010 initialization Dear Wilhelm, I was reading your replies to this issue at the EtherLab-Users mailing list and it was very helpful for me. http://lists.etherlab.org/pipermail/etherlab-users/2012/001860.html I'm trying to configure a Can Network from the Beckhoff Can Master Module EL6751 with only one can slave (Phoenix Contact Can I/O Terminal). I just do it the steps like the configuration of the EL6731 (Profibus Master Module): - Configure the Can Network with TwinCAT - Export the XML - Format it with xmllint - And take the necessary data: * PDOs Entries: Tx and Rx * StartUp SDO config of the next Index: + 0x1C32 + 0x1C33 + 0xF800 + 0x8000 + 0x8001 + 0x8002 + 0x8003 - Implement the C code for the configuration, but I keep out from the app without error at the function: * ecrt_slave_config_complete_sdo(sc, 0x1C32, pb_config_buf, cnt); The last dmesg is: [ 9574.754735] EtherCAT: Requesting master 0...
