SCALEXIO Serial Interface Solution

Using Serial Peripheral Interface (SPI) and Inter-Integrated Circuit (I2C) bus

The SCALEXIO Serial Interface Solution lets you connect a SCALEXIO real-time system to an SPI and I2C bus. The solution can be used as decentralized I/O.  

La solution SCALEXIO Serial Interface vous permet d’utiliser les bus Serial Peripheral Interface (SPI) et Inter-Integrated Circuit (I2C) avec un système SCALEXIO. Cette solution consiste en une carte de base pour solutions d’E/S spécifiques, équipée du module DS2655M2 Digital I/O Module, et des fonctions d’E/S personnalisables pour le paramétrage de ces interfaces avec ConfigurationDesk.

La solution peut être installée dans une unité d’E/S externe, un système rack SCALEXIO ou une SCALEXIO LabBox.
