Overview

PROFIBUS is an open serial communication standard that enables data exchange between all kinds of automation compo-

nents. The PDP32.0 communication interface is a PROFIBUS DP (Decentralized Periphery) slave on the PROFIBUS network.

PROFIBUS DP is standardized in IEC 61158 together with other fieldbus protocols.

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 meters, depending on the selected transmission rate. Up to 32 nodes can be connected

to the same PROFIBUS network segment without the use of repeaters. With repeaters, it is possible to connect 126 nodes

(including repeaters and a master station) to the network. In PROFIBUS communication, the master station – usually a

programmable logic controller (PLC) or a distributed control system (DCS) – polls nodes, which respond and take the actions

requested by the master. The PROFIBUS protocol family is specified in the IEC 61158 standard. For further information on

PROFIBUS, refer to the above-mentioned standard.

The PDP32.0 PROFIBUS DP communication module is an optional device for the ABB motor controllers UMC100.3 which

enables the connection of the UMC100.3 to a PROFIBUS network. The UMC100.3 with PDP32.0 is considered a slave on the

PROFIBUS network.

Through the communication module, you can:

• give control commands to the UMC100.3 (for example Start, Stop, Fault reset)

• read status information and actual values from the UMC100.3

• read/write UMC100.3 parameter values
