EtherCAT
R2025b用于控制自动化的以太网 (EtherCAT) 是一种面向实时分布式控制的开放式以太网网络协议。请参阅 www.ethercat.org 。
首先，使用 EtherCAT 网络配置器配置网络，然后将配置加载到 EtherCAT 协议模块中。这些模块连接至支持 EtherCAT 协议的 Intel® 以太网板，并与 PCI 标准总线架构兼容，例如 PCI、PCI Express® 和 PXI®。
Simulink® Real-Time™ 支持 Beckhoff® TwinCAT® 配置器和 Acontis EC-Engineer 配置器。
有关配置器的详细信息，请参阅制造商文档（ www.beckhoff.com 和 www.acontis.com/en/ ）。有关 EtherCAT 电路板的详细信息，请参阅制造商文档。
