As such you probably shouldn’t include it in your PDO mapping structure. I think the master code is smart enough to align it correctly anyway, but I must admit I haven’t really experimented with that sort of layout.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><div style='border:none;border-left:solid blue 1.5pt;padding:0cm 0cm 0cm 4.0pt'><div><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0cm 0cm 0cm'><p class=MsoNormal><b><span lang=EN-US style='font-size:10.0pt;font-family:"Tahoma","sans-serif";color:windowtext'>From:</span></b><span lang=EN-US style='font-size:10.0pt;font-family:"Tahoma","sans-serif";color:windowtext'> etherlab-dev-bounces@etherlab.org [mailto:etherlab-dev-bounces@etherlab.org] <b>On Behalf Of </b>Jürgen Kunz<br><b>Sent:</b> Wednesday, 13 March 2013 06:34<br><b>To:</b> etherlab-dev@etherlab.org<br><b>Subject:</b> [etherlab-dev] PDO entry with Index 0x0000, missing PDO registration<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Hello,<br><br>I had the problem with a new slave-type that only the first of four slaves worked (OP), all others were in SAFEOP +ERROR. In the debugging output of the master (ethercat debug 1) I saw that only some of the PDOs of the first slave hat been registered in the domain, the PDOs of the other slaves had not been registered.<br>The cause is that one of the PDOs have an entry index of 0x0000 (see pdos.txt), which causes the ecrt_domain_reg_pro_entry_list to quit, so all other PDO entries after that are ignored.<br>With the attached patch (diff.txt) I get all slaves to work.<br><br>Regards,<br>Jürgen Kunz<o:p></o:p></p><div><p class=MsoNormal>-- <br>Dipl.-Inform.
