Key Document

Description

This reference design demonstrates how to connect a C2000 Delfino MCU to an EtherCAT™ ET1100 slave controller. The interface supports both demultiplexed address/data busses for maximum bandwidth and minimum latency and a SPI mode for low pin-count EtherCAT communication.  The slave controller offloads the processing of 100Mbps Ethernet-based fieldbus communication, thereby eliminating CPU overhead for these tasks.

Features
  • High-Bandwidth, low-latency interface to Beckhoff ET1100 EtherCAT Slave Controller
  • Asynchronous 16-bit parallel interface with demultiplexed address/data bus
  • Eliminates CPU overhead for EtherCAT frame processing
  • Includes example code for direct memory R/W of ET1100 Dual-port RAM
