Overview
Communication Features
The 1769-SM2 supports two operating modes for different drive network configurations:
- Single Mode: Supports one PowerFlex 4-class drive connection.
- Multi-Drive Mode: Supports up to five PowerFlex 4-class drive connections per channel, with 15 connections across all three channels.
Each channel uses an RJ45 connector for communication. Meanwhile, DSI/Modbus network support allows the module to exchange data with connected drives. The operating mode determines the number of drive connections available.
