Allen-Bradley 1769-SM2 DSI Module For PowerFlex Drives

The Allen-Bradley 1769-SM2 Compact I/O to DSI/Modbus Communications Module links a 1769 Compact I/O rack to PowerFlex drives via the Drive Serial Interface (DSI), providing a non-Ethernet path for driving and monitoring PF drives from a Rockwell controller. It implements DSI communications and functions as a Modbus RTU master, enabling readouts of drive status and fault data and the ability to send control commands through a standardized data map for PowerFlex 4-class drives. Designed for use with PowerFlex drives, the SM2 supports multi-drive configurations from a single module, helping reduce wiring and simplify drive integration in panel-mounted automation systems. The module fits the 1769 Compact I/O form factor and is configured and commissioned within Rockwell software tools such as Studio 5000 and RSLogix, providing a compact, centralized interface for drive integration in non-Ethernet control schemes.
