Has anyone had experience using a "CU1128 | EtherCAT junction" from Beckhoff (*) with the etherlab master?

It seemingly looks like a dumb device, but the documentation hints at particular steps to set it up with TwinCAT:

Topological configuration
With the CU1128, special attention should be paid to the sequence of the EtherCAT slaves. Since the CU1128 has 7 junction ports, drop lines connected to ports must and can be clearly identified in practice. If incorrect information is provided in the configuration (TwinCAT System Manager file *.tsm), the system cannot start.
