    I use softmotion with Beckhoff ethercat, EK1100 and EL7031 drive for the motor.
    Everything works ok, but if I logout and login again I always get an error on the EL7031: bus not running.
    Ethercat and EK1100 are OK
    Same issue on normal PC and on raspberry Pi
    I think this is safety issue to prevent unwanted motion after a stop.
    can only solve this to download the program again.
    How can I solve this or I,m I doing something wrong?

    Edwin,

    Error appears when I stop the plc running and start again
    if I logout with plc running and log in again it is ok.

    plc log :
    AL status read from slave adress1002 status 16#18
    watchdog for opmode expired.adress1002

    (1002 =el7031)

    ps: what should be setting of bus cycle task . use parent bus cycle settings or activate 1 or acivate 2
    I have been playing with these setting , but what is the right setting .
    for example I have an el1008 not working if I choose use parent bus cycle setting.

    I find short description in:
    ethercat mapping : tab <device>I/o mapping refresch variables , but it is not very clear to me .</device>
