Communication interfaces (2 of 3)

Feature

Functional description

Ethernet switch (ETHSW)

● 3-port PHY interfaces

● IEEE802.3

● Support for 10/100/1000 Mbps data transfer

● Full and half duplex (1000 Mbps supports full-duplex only)

● Hardware switching, lookup, and filtering

● QoS with frame prioritization

● Priority control based on VLAN Priority (IEEE802.1q), which enables priority reassignment

● Classification and priority assignment based on IPv4 DiffServ Code Point Field, IPv6 Class

of Service

● Queue with eight priority levels

● Multicasting and broadcasting

● VLAN frame

● IEEE 1588-2008 compatible

● Programmable addition, removal and manipulation of ingress and egress VLAN tags,

supporting single and double-tagged VLAN frames on each port

● Cut-through and hub features

● Device level ring (DLR)

● Programmable egress rate limit per port

● Ingress Configurable Broadcast/multicast storm protection per port

● IEEE802.1X source address authentication supported

● IEEE802.1X guest VLAN supported

● PRP functionality (IEC 62439-3 edition 2.0- 2012)

● Configurable Time Multiplexed (TDMA) output queue scheduler supporting real-time

network infrastructures using time slots for bandwidth reservation enabling deterministic

delays

● Pattern matchers 12 channels

● Independent two timer module are available for timestamping and time for TDMA.

● Remote monitoring through SNMP

● Powerlink capable hub

● Ingress filtering and frame header manipulation (active stream identification, flow metering)

with Enhanced Frame Parser

● 4 additional PTP timer pulse generators

● MAC to MAC connection

● MII/RMII/RGMII interface is supported

EtherCAT slave controller (ESC)*1

● 1 channel (3 ports)

● EtherCAT Slave Controller IP core (made by Beckhoff Automation GmbH) implemented

● Full-duplex and half-duplex communication

● Data length: 7 to 9 bits (Asynchronous mode)

● Bit rate modulation

● Double speed mode

● Loopback function to enable self-diagnosis (Asynchronous, Clock synchronous mode)

I2C bus interface (IIC)

● 3 channels

● Communication formats: I2C bus format or SMBus format

● Master or slave mode selectable

● Supports the multi-master

● Maximum transfer rate: 400 kbps (Standard mode and Fast mode)
