Devices that can be connected to PROFIBUS-DP devices
An extremely wide range of devices can be connected on the PROFIBUS DP as a DP master
or as DP slaves, provided their behavior complies with
IEC 61784-1:2002 Ed1 CP 3/1. These
include the devices of the following product families:
● SIMATIC S7/M7/C7
● SIMATIC programming devices/PCs
● SIMATIC HMI (operator panel (OP), operator station (OS), and text display (TD) operator
control and monitoring devices)
● Distributed I/O stations
● Devices from other manufacturers
Structure of a PROFIBUS DP network
The figure below illustrates a typical PROFIBUS DP network structure. The DP master is
integrated in the relevant device, for example the S7-400 as a PROFIBUS DP interface. The
ET 200iSP distributed I/O stations are connected to the DP masters via PROFIBUS DP and
PROFIBUS RS 485-IS.
