Operation and Communication
7 Operation and Communication
7.1 Communication via PROFIBUS
7.1.1 General Information on PROFIBUS DP
The PROFIBUS DP is a standardized, open fieldbus, which enables data exchange between
PLCs, PCs, operating and observation devices, and also sensors and actuators.
For more detailed information on the PROFIBUS DP, refer to the PROFIBUS standard EN
50170 and to the current literature on the subject (e.g. M. Popp, "The New Rapid Way to
PROFIBUS DP" available (in German) from the PROFIBUS user organization).
Note!
The PROFIBUS User Organization e.V. Haid- and Neu-Str. (PNO) publishes informational
brochures and a PROFIBUS product catalog (www.PROFIBUS.com).
7.1.2 PROFIBUS DP Communication Parameters
The communication parameters can be taken from the GSD file. The GSD file name is
pf0d7b.gsd.
7.1.3 PROFIBUS DP features
The following is a list of the most important performance features of PROFIBUS DP:
DP slave functionality with functions Data_Exchange, RD_Inp, RD_Outp, Slave_Diag,
Set_Prm, Chk_Cfg, Get_Cfg, Global_Control, Set_Slave_Address.
Modular DP slave device with one module each for writing and reading data.
Transfer rates of 9.6 kbit/s, 19.2 kbit/s, 93.75 kbit/s, 187.5 kbit/s, 500 kbit/s, 1.5 Mbit/s,
3 Mbit/s, 6 Mbit/s and 12 Mbit/s auto-synchronizing.
Adjustable device address 00h
7.1.4 PROFIBUS DP functions
Function Description
Set_Prm Transfers parameter data to a DP slave
Chk_Cfg Transfers the configuration data for testing to a DP slave
Get_Cfg Reads out the configuration data of a DP slave
Data_Exchange Sends output data to a DP slave device and requests input data from a DP slave Class 1
RD_Inp Reads the input data of a DP slave
RD_Outp Reads the output data of a DP slave
Global_Control Sends special commands to one or more DP slaves
Slave_Diag Reads the diagnostic information of a DP slave
Set_Slave_Address Modifies the device address
7.1.5 PROFIBUS Modules
The PROFIBUS address for the reader can be modified in a non-volatile manner via the
"Change station address" (Set_Slave_Add) PROFIBUS function when switching on in a point-
to-point connection.
The default address for the reader is 3
1 word = 16 bit value
1 byte = 8 bit value
7Eh.
