I have B&R X20 modules, and am investigating EtherCAT for a project. This is not a “ask your distributor” kind of project - it’s me playing around and learning.
I have been looking at the X20BC00G3 bus controller, but am not understanding the topology yet.
Do X20 modules onto the side of the bus controller, like with other bus controllers? Only the left side of the bus controller is ever shown. I imagine I would get orange end plates, just like other X20 module stacks.
from the X2X slices point of view, it’s exactly like with every other bus controllers: the’re attached to the right side of the controller.
The difference between those 2 controller setups on the picture is only, that the extended bus controller backplane has a slot also on the left side to plug an additional fieldbus interface of type “X20IFxxxx-1” (for example a CanOpen interface).
So if you don’t need a additional fieldbus interface reachable via the Ethercat slave, the left configuration is enough to control X20 slices via Ethercat.
