EtherCAT: recognise slave bit error was created by bkt
if I send one of my drives in error, for example by disconnecting the power of only one, I see from Lcnc the errors reported by drive statur only until aqundo the drive does not reset and automatically goes into OP. At that point, however, Lcnc master ethercat no longer communicates with the drive and I have no way of making the problem appear on the pyvcp panel ... the error is visible on the terminal:
if would to use PDOS entry 603F error list of my driver for to check error code .... how to write my xml? actually they are:
OR Is there a way to detect this problem from Lcnc without making requests to the drive?
Thanks for any suggest

hi,
if you loose power or ethernet connection you are lost.... Etherlabmaster does no reconnect, you have to restart the system... (its not twincat...)
normal errors in connected state you can read out (overvoltage, overcurrent etc. ) with the error register.
you can try :
<pdoEntry idx="603F" subIdx="00" bitLen="16" halPin="errorcode" halType="u32"/>
at the end of the 1a01 section .
check if the mapping works, if not more informations about the drive are neccesary
