The PROFIBUS Master protocol driver exists as a single port implementation.
The driver can be configured as a Class 1 PROFIBUS Master to interface with
other PROFIBUS slave devices. The unit is also used for configuration of the
nodes on the PROFIBUS network. It provides access to both standard as well as
extended diagnostic information and freeze/sync capability. The PROFIBUS
master port can be used to continuously interface with PROFIBUS slave devices
over a serial communication interface (RS-485).
2.1 About the PROFIBUS Protocol
PROFIBUS (Process Field Bus) is a widely-used, open-standards protocol
created by a consortium of European factory automation suppliers in 1989.
PROFIBUS is a master/slave protocol. The master establishes a connection to
the remote slave. When the connection is established, the master sends the
PROFIBUS commands to the slave. The PDPM module works as a master only.
The module uses an internal database to pass data and commands between the
processor and the client and server devices on the PROFIBUS network.
PROFIBUS supports a variety of network types. The network type supported by
the PDPM module is PROFIBUS DP (Device Bus), which is designed for remote
I/O systems, motor control centers, and variable speed drives.
2.2 PROFIBUS DP Architecture
The PROFIBUS DP Master network supports multiple Master systems with
several slaves.
The following table shows the most important features of PROFIBUS DP Master:

2.2.1 Bus Access
Two different bus access procedures handle the various communication
requirements for the PROFIBUS DP Master topology:
Token Passing
Polling
2.2.2 Token Passing
Token passing ring is the basis for communication between the more complex,
active stations. All stations have the same rights in that a token is passed from
station to station in a logical ring. The token is passed to each station with a
maximum, definable token cycle time. A station is given transmission rights for
the duration of time that it has the token.
2.2.3 Master/Slave Polling
Master/slave polling guarantees a cyclic, real-time based data exchange
between the station with transmission rights, the active station, and its
subordinates, the passive stations. In this case, the Master is able to pass data to
the slave and/or receive data. The services in layer 2 (field-bus data link in ISO-
OSI reference model) organize this communication.
2.3 Communication Types
In addition to point-to-point data transfer, the PROFIBUS protocol can also
handle the following types of communication.
Broadcast communication: An active node sends an unacknowledged
message to all other nodes (Master and slaves)
Multicast communication (control instructions): An active node sends an
unacknowledged message to a group of nodes (Master and slaves)

2.4 Master/Slave Communication Phases
The communication between the Master and the slaves takes place in the
following phases:
Parameterization and configuration phase
Usable data transfer phase
Before a DP slave can be integrated into the usable data transfer phase, the
parameterization and configuration phase runs a device identification test that
verifies that the planned configuration matches the actual device configuration for
each slave in the PROFIBUS network. The test verifies that:
The device is actually there
It is the right type of device
The station address set on the device matches the station address in the bus
configuration
The formats, telegram length information, and bus parameters are correct
and
The number of configured inputs and outputs is correct
2.5 Module Internal Database
The internal database is central to the functionality of the module. This database
is shared between all the ports on the module and is used as a conduit to pass
information from one device on one network to one or more devices on another
network. This permits data from devices on one communication port/network to
be viewed and controlled by devices on another port/network. In addition to data
from the master port, status and error information generated by the module can
also be mapped into the internal database.

In addition to data from the master port, status and error information generated
by the module can also be mapped into the internal database.
2.6 Master/Slave Communication Phases
The communication between the Master and the slaves takes place in the
following phases:
Parameterization and configuration phase
Usable data transfer phase
Before a DP slave can be integrated into the usable data transfer phase, the
parameterization and configuration phase runs a device identification test that
verifies that the planned configuration matches the actual device configuration for
each slave in the PROFIBUS network. The test verifies that:
The device is actually there

Note: On all ProLinx modules, data from the application port on the main board, serial Port 0, is not
buffered. Packets go directly to and from the serial chipset to the processor. This has the potential
to cause the serial communications to become erratic at baud rates above 38,400 baud.
ProLinx modules with 4 serial ports have a separate serial interface board for serial Ports 1, 2, and
3. These serial ports are buffered and can handle communications up to 115,200 baud.

The ProLinx SyCon PROFIBUS is a PROFIBUS-DP configurator that provides an
automatic means of configuring a PROFIBUS Master Module. All devices are
configured using a single tool which checks dependencies between devices and
thereby only allows configurations that make sense.
In addition, ProLinx SyCon documents the fieldbus system. Detailed
configuration documentation may be printed out that includes details between the
bus topology and the utmost detail of a single device. ProLinx SyCon supports
standardized files that contain information about all features and limitations of the
slave device and uses these files for configuration.
Lastly, the ProLinx SyCon is equipped with a diagnostic mode that allows viewing
of fieldbus status information.

The System Installation program automatically launches the PROLINX SyCon
installation program. When prompted for components to install, choose
Configurator and CIF Device Driver.
GSD Files
Each PROFIBUS-DP manufacturer uses standard device description files to
define the PROFIBUS-DP device functionalities on the network. These definitions
are called GSD files. The set of device description files (GSD files) build the
device database.
PROLINX Devices
The GSD files for PROLINX devices are located on the ProLinx Solutions DVDin
the \ProLinx\Utilities\PDPS_GSD folder.
Refer to E:\ProLinx\Utilities\PDPS_GSD\ProLinx_PDPS\readme.pdf to determine
the correct GSD files to use.
To import the ProLinx GSD files:
1 In SyCon, open the File menu, and choose Copy GSD.
2 In the Copy GSD dialog box, navigate to your DVDdrive, and select the path
\ProLinx\Utilities\PDPS_GSD.
3 Press [Ctrl][A] to select all the GSD files in that folder, and then click Open.
4 You will be prompted to import the BMP files that accompany the GSD files.
Click Open to import each of the selected BMP files.
Other Devices
For other devices, these files should be provided and updated by the device
manufacturer.

Configuration PDPM ♦ ProLinx Gateway
Protocol Manual PROFIBUS DP Master

June 24, 2013
You can also get the GSD files from the homepage of the PROFIBUS user
association:
http://www.PROFIBUS.com (http://www.profibus.com)
For all available configurations, GSD files must be contained in the directory
GSD. During installation of the program PROLINX SyCon, the available files will
be included. If you need another GSD file during PROLINX SyCon runtime you
have to copy this file with the menu item File - Copy GSD.
The GSD directory path is changeable. To modify it from the default to another
path use the menu Settings - Path.
All GSD files have to be present in this directory. The default path for ProLinx
SyCon GSD files is
C:\Program Files\HMS\SyCon\Fieldbus\PROFIBUS\GSD
At program startup, PROLINX SyCon automatically reads in all GSD files that are
present in the GSD directory. Because of this, device names are placed in an
internal list. The device-specific data is taken online directly from the GSD file
during the configuration phase.
If you must use a GSD file that is not included in the selection list during the
configuration phase, you have to copy the file to the GSD using the File - Copy
GSD command. If you use this option or manually copy a file to the directory
using Windows Explorer, you must activate the Reread command using the
menu Settings - Path and OK acknowledgement.
In the menu Tools - GSD Viewer all GSD files of the directory are shown.
3.1.3 Configuring a PROFIBUS Using PROLINX SyCon
Basic Configuration
ProLinx SyCon configures the PROFIBUS system quickly and easily.
Perform the following procedure to configure the PROFIBUS system.

family. If a slave is selected, information about that slave appears below the
Available slaves list box..
With a double click or with the button Add, the slave appears in the right list box.
All devices in this box will be connected to the active master displayed in the
Master window. You must select each slave one-by-one. You can also give each
a device a name or a short description in the Description Field.
The Station address field increments with each addition of a new slave. However,
this address may be overwritten.
Note: It is possible to choose one slave several times but each device must have its own station
address to distinguish them on the network.
Configuring a Slave
Slave-specific configuration is accomplished using the Slave Configuration dialog
box. Here, modules and associated data are assigned to the address of the
process data image in the master device. These addresses correspond to the
application in the PLC.

There are two types of DP-slaves; simple and modular. A simple slave has a
fixed data length. A modular slave's data length is configurable. This type of
slave can be understood as an assembly of one or more simple slaves with one
bus address.
The upper table contains all available modules of the slave. In the case of a
simple slave, there is only one module that is automatically copied into the lower
table by ProLinx SyCon. A modular slave must be copied by the user by double-
clicking on the module or selected module in combination with the Append
Module button.
If a module has several inputs or outputs (sub modules), more lines appear in the
configuration table. These additional lines will be signed with a higher index in
the column Idx. The column Slot counts the modules.
Perform the following steps to configure the modules of the slave:
1 If not already present, select all modules from the upper table and insert them
in the lower table to be configurable.
2 The sequence of the modules in the lower list is important and must
correspond to the real physical slave configuration.
