The Ethernet port multiplier is a central infrastructure device for extensive automation technology installations. It extends the controller's 1 Gbit port to multiple 100 Mbit Ethernet ports, which can then pass normal Ethernet or EtherCAT frames through.
Typical conditions that require the use of the Ethernet port multiplier are:
- use of EtherCAT cable redundancy in conjunction with distributed clocks
- EtherCAT systems with a large number of devices and/or a data throughput of >100 MBit/s
- a need for additional Ethernet ports on the Industrial PC controller
