ECAT EtherCAT® slave controller

Highlights

EtherCAT® is one of the major Industrial Real Time Ethernet protocols with Ultra high-speed right up to the terminal

Outstanding performance, flexible topology which save costs for additional Ethernet equipment (Switches) and simple configuration characterize EtherCAT®

Customer benefits Key features

Smallest fully integrated EtherCAT® Slave Node

Fully compatible with Beckhoff’s ET1100 ASIC

Multiple on chip trigger connection using Sync/Latch signals

› Scalable from a 100 QFP package up to a 196 LFBGA fully integrated

› Avoids complex porting of EtherCAT® stacks, reuse of own written stacks

› Use of Sync/Latch signals to trigger the internal ADC/CCU or capture from CCU

› EtherCAT® ASIC’s, SOC and FPGA need additional components

– ASIC’s need a micro

– FPGA need external memory's and are in big BGA

– Clocks must be supported twice in some topologies

› XMC4800 combines all that in a 100 QFP

– No external components needed

– Easy to be handled in PCB production

– Many different interfaces available in one package

ECAT Multiple on chip trigger connection

› Sync outputs are available on pins, can be used as ADC trigger and via ERU connected to CCU4/8, DSD, POSIF

› Input of Latch signals can be generated by both ERU and pins

– ERUs combine combinatorial signal combinations and module/protocol trigger

› Intelligent I/Os and PLCs

› Industrial drives

System integration

Due to the multilayer bus matrix, CPU can operate EtherCAT® data while a Ethernet DMA moves data to an internal memory without timing penalty.

Complex application scenarios can be realized by a highly flexible internal integration of several standard communication interfaces.

Application example Isolated intelligent I/O’s

In brief

In most automation systems an isolation is needed. The XMC48 offers the possibility for a isolation of the XMC™ MCU and transferring the data over EtherCAT® in a single chip solution.

EtherCAT® is one of the Industrial Ethernet Protocols which is more and more used in Industrial Automation Systems. Starting from simple I/O slices up to complex inverter architectures, EtherCAT® solves the needs of fast real time communication.

In brief

In combination with the XMC4800 complex solutions like multiple encoder or resolver interfaces in a single chip EtherCAT® solution can be developed. The XMC™ with its huge set of peripherals and hardware trigger using SYNC/LATCH signals demonstrate a ideal solution.
