ECAT-2515 is 1-to-5 port EtherCAT junction SubDevice. It is designed to implement wiring deployment by daisy chain and branch more flexibly and easy to maintain.
 

Benefit 1: Translate Daisy-chain to Branch Topology

EtherCAT junction slaves can implement wiring in branch topology. The wiring of branch topology is easier than daisy-chain topology.

Benefit 2: Improve the Debugging Efficiency

For daisy-chain topology, if a SubDevice is not working or the cable is disconnected, all SubDevice in the same network will not be able to communicate with the Main Device controller.

With EtherCAT junction slaves, all SubDevice can be wired as separated sections. If one SubDevice is failed, only the SubDevice in the same section will be affected. With the help of EtherCAT junction SubDevice module, the SubDevice in other sections still can communicate with the Main Device controller. Debugging can be done separately, thus improving the debugging efficiency.

 

Cable Redundancy

Cable redundancy is a ring topology. When the communication cable on one side is disconnected, it can also communicate through the cable on the other side to ensure the stable operation of the control system. The structure is as follows.
