应用领域

dSPACE EtherCAT 从接口能将PHS dSPACE系统连接到以太网现场总线 EtherCAT,作为从属设备。EtherCAT 副接口的典型应用实例是自动化技术中的实时应用程序，比如过程自动化或测试台。

主要优点

通过dSPACE EtherCAT 从接口，您可以使用高性能 EtherCAT 网络。

EtherCAT

EtherCAT是一种开放、高性能、基于以太网的现场总线系统，能够帮助自动化应用实现短周期时间和低通信抖动。EtherCAT从设备读取传递的数据，并在电报通过时注入输入数据。帧在每个节点中仅延迟几微秒，并且许多节点只能用一帧进行寻址。EtherCAT是一个国际标准（更多信息，请参见www.ethercat.org）。

硬件和软件

EtherCAT从接口由带有背板模块的DS5202 FPGA基板组成，背板模块至多携带两个Beckhoff EtherCAT模块FB1111-0140。该支架具有两个RJ45插头插座，用于连接到EtherCAT网络。EtherCAT模块集主要由基础库和模板模型生成器组成。用户创建的配置M结构中生成包含所有必需模块的模型。

1)The end of life of the dSPACE Solutions for PHS (peripheral high-speed) systems is planned for December 31, 2024. You can still buy the related products up to and including December 31, 2021. New Releases of dSPACE software will still support the dSPACE PHS hardware for modular systems until at least the end of 2023. After the end of life, no services of any kind will be available for these products. We advise against using the PHS hardware products in new projects. For new projects we recommend that you use SCALEXIO, the latest dSPACE technology for modular real-time systems.
