Which devices can be connected to PROFIBUS DP?
The most varied devices can be connected as DP masters or DP slaves to the PROFIBUS DP, the
only proviso is that they behave in accordance with the standard
IEC 61784-1:2002 Ed1 CP 3/1. Among others, devices of the following product families can
be used:
• SIMATIC S7 / M7 / C7
• SIMATIC S5
• SIMATIC PD / PC
• SIMATIC HMI (operator panel (OP), operator station (OS), and text display (TD) operator
control and monitoring devices)
• 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 respective device, e.g. if the S7-400 has a PROFIBUS DP interface, the
master connection IM 308-C is connected with an S5-115U. The DP slaves are the distributed
I/O devices that are linked with the DP masters via the PROFIBUS DP.
