ABB RPBA-01 PROFIBUS DP adapter module
The RPBA-01 PROFIBUS-DP Adapter module is an optional device for ABB drives which enables the connection of the drive to a PROFIBUS network. The drive is considered as a slave on the PROFIBUS network. Through the RPBA-01 PROFIBUS-DP Adapter module, it is possible to:
•give control commands to the drive (Start, Stop, Run enable, etc.)
•feed a motor speed or torque reference to the drive
•give a process actual value or a process reference to the PID controller of the drive
•read status information and actual values from the drive
•change drive parameter values
•reset a drive fault. The PROFIBUS commands and services supported by the RPBA-01 PROFIBUS-DP Adapter module are discussed in chapter Communication. Please refer to the user documentation of the drive as to which commands are supported by the drive. The adapter module is mounted into an option slot on the motor control board of the drive.

PROFIBUS is an open serial communication standard that
enables data exchange between all kinds of automation
components. There are three main variations of PROFIBUS:
PROFIBUS-FMS (Fieldbus Message Specification), PROFIBUSDP (Decentralised Periphery) and PROFIBUS-PA (Process
Automation). The RPBA-01 PROFIBUS-DP Adapter module
supports the PROFIBUS-DP protocol only.
The physical transmission medium of the bus is a twisted pair
cable (according to the RS-485 standard). The maximum length of
the bus cable is 100 to 1200 metres, depending on the selected
transmission rate (see Technical data chapter). Up to 31 nodes
can be connected to the same PROFIBUS network segment
without the use of repeaters. With repeaters, it is possible to
connect 127 nodes (including repeaters and master station) to the
network.
In PROFIBUS communication, the master station – usually a
programmable logic controller (PLC) – polls the nodes which
respond and take the actions requested by the master. It is also
possible to send a command to several nodes at the same
broadcast; in this case the nodes do not send a response
message to the master. Communication between nodes is not
possible on a PROFIBUS network.
