Introduction
Media converter, Ethernet/EtherCAT, 100 Mbit/s, 24 VDC
The EP9521-0020 EtherCAT/Industrial Ethernet Module for Industrial Fast Ethernet/100 Mbit/s is a media converter for conversion from fiber optic to copper physics and vice versa. It is suitable for multi-mode fiber optics and is used for direct transition from one medium to another. The media converter always works bidirectionally and collision-free with a constant delay and can be diagnosed as a self-contained EtherCAT device. As opposed to standard media converters, the EP9521-0020 therefore guarantees fast link control and thus a secure termination of the EtherCAT segment even in case of a fault. Since the transfer direction (copper to fiber optic | fiber optic to copper) is relevant for the bus, the device can be configured via a switch. "Link Loss Forwarding" can also be set for normal Ethernet operation via this switch.
This solution is ideal in applications where EtherCAT transfers over large distances are required or where higher EMC loads on the bus line are to be expected.
