Communication

Overview

This chapter describes the PROFIBUS messaging used in the

communication with the drive, and PROFIBUS slave device

configuration messages.

PROFIBUS DP

The FPBA-01 module supports the PROFIBUS DP (DP-V0)

protocol according to the IEC 61784 and EN 50170 standards.

PROFIBUS DP-V0/DP-V1 is a distributed I/O system which

enables the master to use a large number of peripheral modules

and field devices. The data transfer is mainly cyclic: the master

reads the input information from the slaves and sends the output

information back to the slaves.

The FPBA-01 module uses so-called PPOs (Parameter/Process

Data Objects) in cyclic communication and supports also two

standard telegrams (1 and 20). See Figures 14 and 15 for the

supported PPO messages and standard telegrams respectively.

Note: Standard telegrams are part of the DP-V1 extensions which

are not supported by the FPBA-01 as yet.

Service Access Points (SAPs)

The services of the PROFIBUS Data Link Layer (Layer 2) are

used by PROFIBUS DP through Service Access Points (SAPs).

Precisely defined functions are assigned to individual SAPs.

For further information on Service Access Points, refer to the

manual of the PROFIBUS master, PROFIDRIVE – The

PROFIBUS Profile for Adjustable Speed Drives V2.0 and V3.1, or

the EN 50170 and IEC 61784 standards.
