<body class='hmmessage'><div dir='ltr'>Hi everybody,<br><br>I have a problem with my EPOS3 controller. It seems to initialize fine but when activationg "debug 1" a warning is already seen, regarding timed out and unmatched datagrams. Is this a problem for later communication or normal? Where could I further check? The results of dmesg are attached in the end of the mail.<br><br>The reason for my question is also the later communication. When trying to further communicate with the device I get more errors. Again timed out datagrams and SDO download is not possible.<br>I am also not quite sure what the error message means with "local control". Are there options on the slave that have to be changed or is that something regarding the master?<br><br>Thank you very much for any help! <br>Peter Plötner<br><br><br>[11772.846496] e1000e: eth1 NIC Link is Up 100 Mbps Full Duplex, Flow Control: None<br>[11772.846501] e1000e 0000:0d:00.0: eth1: 10/100 speed: disabling TSO<br>[11772.846796] EtherCAT 0: Link state of ecm0 changed to UP.<br><b>[11772.850868] EtherCAT WARNING 0: 1 datagram TIMED OUT!<br>[11772.850868] EtherCAT WARNING 0: 1 datagram UNMATCHED!</b><br>[11772.928009] EtherCAT 0: 1 slave(s) responding on main device.<br>[11772.928012] EtherCAT 0: Slave states on main device: INIT.<br>[11772.929729] EtherCAT 0: Scanning bus.<br>[11773.168081] EtherCAT 0: Bus scanning completed in 276 ms.<br>[11773.168081] EtherCAT 0: Using slave 0 as DC reference clock.<br>[11773.208006] EtherCAT 0: Slave states on main device: PREOP.<br><br><br>[11810.402803] EtherCAT: Requesting master 0...<br>[11810.402807] EtherCAT: Successfully requested master 0.<br>[11810.405810] EtherCAT 0: Domain0: Logical address 0x00000000, 52 byte, expected working counter 3.<br>[11810.405812] EtherCAT 0: Datagram domain0-0-main: Logical offset 0x00000000, 52 byte, type LRW.<br>[11810.405822] EtherCAT 0: Master thread exited.<br>[11810.405825] EtherCAT 0: Starting EtherCAT-OP thread.<br><b>[11810.405850] EtherCAT WARNING 0: 9 datagrams TIMED OUT!<br>[11811.434178] EtherCAT ERROR 0-0: SDO download 0x1603:01 (4 bytes) aborted.<br>[11811.434178]
