PREOP+E corresponds to a value of 0x12. Note however that the master stack will <i>usually</i> auto-acknowledge errors and try configuring again, so the E state will be transitory; an exception is if it encountered an unrecoverable error or otherwise gave up, in which case the error_flag field in both ec_slave_info_t and ec_slave_config_state_t will be set. So generally you should just check for the error_flag and ignore the actual E state. (The al_state except for the E state can also be read from ec_slave_config_state_t, via ecrt_slave_config_state.)<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D;mso-fareast-language:EN-US'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D;mso-fareast-language:EN-US'>I’m not sure what you mean by Vendor Specific Offsets.<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D;mso-fareast-language:EN-US'><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 #E1E1E1 1.0pt;padding:3.0pt 0cm 0cm 0cm'><p class=MsoNormal><b><span lang=EN-US>From:</span></b><span lang=EN-US> etherlab-users [mailto:etherlab-users-bounces@etherlab.org] <b>On Behalf Of </b>Michael Asher<br><b>Sent:</b> Saturday, 9 April 2016 05:36<br><b>To:</b> etherlab-users@etherlab.org<br><b>Subject:</b> [etherlab-users] AL Status Code Reads 0x00 0x00 even when 'PREOP + E' is reported<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><span lang=EN-US>Hi;<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>On what register is the, ‘Slave State + E’ reported, e.g. 'PREOP + E'?
