Which Devices Can Be Connected to the PROFIBUS-DP?
An extremely wide range of devices can be connected to the PROFIBUS-DP as
DP masters or DP slaves, provided their behavior complies with IEC 61784-1:2002
Ed1 CP 3/1. The devices that can be used include the following:
SIMATIC S5
SIMATIC S7/M7/C7
SIMATIC programming device/PC
SIMATIC human-machine interface, or HMI (operator panel, OP; operator
station, OS; and text display, TD)
Devices from other manufacturers
Structure of a PROFIBUS-DP Network
The figure below illustrates a typical PROFIBUS-DP network structure. The DP
masters are integrated in the relevant device – for example, the S7-400 has a
PROFIBUS-DP interface and the IM-115U. The DP slaves are the distributed I/O
systems connected to the DP masters by means of PROFIBUS-DP.
