The Allen Bradley 1769-SM1 is a Compact I/O communication module designed to connect DPI or SCANport-based devices—such as PowerFlex drives—to CompactLogix or MicroLogix 1500 systems. It functions as a communication bridge, enabling legacy drive networks to integrate into modern Compact I/O architectures.
This module is commonly used in retrofit projects where existing SCANport or DPI devices must be retained while upgrading PLC control platforms.
