shadow ethercat slave

[Zimmbo]

Hi,

is it possible to shadow a ethercat slave that is not powered. So ethercat can go to OP. And after i power on the slave the ethercat working on. Actually i will get the problem that i have an topologie missmatch. And the I/Os from the Ethercat and also the Datalayer not update the IOs. All my mapped DI are false. Without so DIs i can not quit the safety and so powered this missing ethercat slave

I configured that the ethermaster like, that slaves have not to reach master state. But i get no I/Os from the operating clamps but they have state OP

You not only need the setting for slaves do not reach EtherCat master state but also use different sync units for the data transmission. See this thread.
