What is PROFIBUS DP?
PROFIBUS DP is an open bus system based on the
IEC 61784-1:2002 Ed1 CP 3/1
standard with the ”DP” transmission protocol
(DP stands for distributed I/O).
PROFIBUS DP is physically either an electrical network based on a shielded
two-wire line or an optical network based on a fiber-optic cable.
The ”DP” transmission protocol allows a rapid, cyclic exchange of data between
the controller CPU and the distributed I/O systems.
What are DP masters and DP slaves?
The DP master links the controller CPU with the distributed I/O systems. The DP
master exchanges data with the distributed I/O systems and monitors the
PROFIBUS DP bus system via PROFIBUS DP.
The distributed I/O systems (= DP slaves) prepare the data of the sensors and
actuators locally so that they can be transmitted to the PLC CPU by
PROFIBUS DP.
Which devices can be connected to the PROFIBUS DP?
An extremely wide range of devices can be connected to the PROFIBUS 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
