Hi K-1, I would also like to know if, I really do not know how it can be calculated, I do not know if the variable lcec.read-all.time or lcec.write-all.time can tell you something? , Regards Chimeno

I have a bus coupler BK1120 for them. Up and running in TwinCAT everything is working fine.

BUT

I sucessfully installed linuxcnc-ethercat and i can see my coupler in slaves. I've read somewhere, that K-Bus is not "transparent" to ethercat master, so i guess that's why i see ONLY my coupler.

Looking through code of linuxcnc-ethercat, it seems to have compatibility only for E-Bus devices (EL.... etc)

Is there any possibilty to "talk" with K-Bus terminals and coupler?



Hello, at the beginning of starting with ethercat, I was also asked if K-bus could work, I remember it was not possible, but you can ask in the Etherlab IGH Ethercat forum if anyone has got it, Regards
