We want to realise a EtherCAT star topology with a ctrlX CORE and several S20-EC-BK. Do we support EtherCAT junction and EtherCAT hub devices t.e. CU1128 from Beckhoff?
We need a star topology to realise systems with a high reliability and availability. One broken device should not shut down the whole system.
Any interoperability tests/results are welcome.
Thanks
The mentioned Beckhoff device CU1128 makes trouble when using the scanning function, when the EC configuration is adjusted manually it works.
An alternative will be a ctrlX IO XB-EC-12 with an upcoming XB-EC-31 (t-plug) where similar to the Beckhoff device a tree can be build. And the good thing here, the scanning is working fine.
When using these configurations, each EC Slave must be in an own Sync Unit otherwise when one is missing or in failure all other data will get invalid too.
May others know alternative solutions.
