The 1769-SM1 is a communication interface module designed for Allen-Bradley CompactLogix and MicroLogix 1500 controllers. It acts as a gateway between the controller and industrial drives, enabling communication through DPI (Drive Peripheral Interface) or SCANport protocols.
The module is commonly used with PowerFlex 7-class drives, allowing the controller to exchange control commands and status data with the drive system. It features automatic device detection and baud-rate synchronization, simplifying setup and reducing configuration time.
For reliable operation, the 1769-SM1 must be installed within six slots of the system power supply to maintain stable voltage levels and communication integrity.
