Allen-Bradley 1769-SM1 Communication Module Overview

The Allen-Bradley 1769-SM1 is a DPI/SCANport communication module for CompactLogix systems. This module belongs to the compact I/O-to-DPI/SCANport module series. The Allen-Bradley 1769-SM1 can be used for expansion I/O on MicroLogix 1500 and CompactLogix controllers. It automatically detects the DPI or SCANport host connected to each channel. The module autobauds to the host's data rate for seamless communication. The Allen-Bradley 1769-SM1 is compatible with PowerFlex 7-Class drives and products that support DPI. It also works with other products that use SCANport communication.
