SCALEXIO Serial Interface Solution

使用Serial Peripheral Interface(SPI)和Inter-Integrated Circuit (I2C)总线

SCALEXIO Serial Interface Solution可以将SCALEXIO 实时系统连接到SPI和 I2C总线。该解决方案可以用作分布式I/O.。

借助 SCALEXIO Serial Interface Solution,可以让客户通过SCALEXIO 系统使用Serial Peripheral Interface (SPI) 和 Inter-Integrated Circuit (I2C) 总线 。该解决方案包括一个配有特定 I/O硬件和软件的 I/O解决方案基板,并与ConfigurationDesk一起对这些接口进行参数化。

该解决方案可以与SCALEXIO机架系统、SCALEXIOLabBox、SCALEXIO AutoBox或外部I/O单元一起使用。通过使用外部I/O单元可以缩短与被测设备的距离,从而实现更高的频率。
