ABB RPBA-01 Overview
The ABB RPBA-01 is a PROFIBUS DP fieldbus adapter module designed specifically for ABB drives—primarily the ACS800 and ACS550 series. It converts the internal control signals of the drive into PROFIBUS DP protocol data frames, allowing the drive to function as a slave device on an industrial fieldbus network. This enables remote monitoring, parameter configuration, and fault diagnostics.
Main Functions
PROFIBUS DP V0/V1 communication with automatic message type detection; supports PPO message types 1–6
Fully compatible with PROFIdrive and ABB drive profiles, enabling direct read/write access to control parameters such as speed, torque, and process values
Slave mode operation:
Sends control commands and process values to the host system
Receives status data, actual values, and parameter updates from the host
Supports remote reset of drive faults
Simplified wiring: only a single PROFIBUS DP cable is required to establish communication between the drive and PLC/host system
Applications
Industrial automation: pumps, fans, compressors, conveyors
Building automation and energy systems: wind power, photovoltaic inverters
Process industries: water treatment, mining, chemical processing, and other systems requiring remote monitoring
