RS485 (DSI) Protocol
PowerFlex 40 drives support the RS485 (DSI) protocol to allow efficient
operation with Rockwell Automation peripherals. In addition, some
Modbus functions are supported to allow simple networking. PowerFlex
40 drives can be multi-dropped on an RS485 network using Modbus
protocol in RTU mode.
For information regarding DeviceNet or other communication protocols,
refer to the appropriate user manual.
Network Wiring
Network wiring consists of a shielded 2-conductor cable that is
daisy-chained from node to node.
