2 Profibus description
PROFIBUS is a manufacturer-independent, open fieldbus standard for a wide
range of applications in manufacturing, process and building automation.
Manufacturer independence and openness are ensured by the international
standard EN 50 170.
Using PROFIBUS, devices from different manufacturers can communicate
without any special interface adjustments. PROFIBUS can be employed for
both high-speed time-critical data transmission and extensive, complex com-
munication tasks. The PROFIBUS family consists of three versions.
2.1 Profibus types
The PROFIBUS family
PROFIBUS DP This PROFIBUS version, which is optimized for high speed and low connec-
tion costs, has been especially designed for communication between auto-
mation control systems (PLC) and distributed field devices (typical access
time: < 10msec). PROFIBUS DP can be used to replace conventional, parallel
signal transmission with 24V or 0/4—20mA.
DPV0: cyclic data transfer:
--> is supported by the recorder.
DPV1: cyclic and acyclic data transfer:
--> is not supported by the recorder.
DPV2: slave-to-slave communication takes place in addition to cyclic and
acyclic data transfer:
--> is not supported by the recorder.
PROFIBUS-PA PROFIBUS-PA has been specifically designed for process engineering. It per-
mits the linking of sensors and actuators to a common bus cable, even in haz-
ardous areas. PROFIBUS-PA enables the data communication and energy
supply for devices in two-wire technology according to the international IEC
1158-2 standard.
PROFIBUS-FMS This is the universal solution for communication tasks at cell level (typical ac-
cess time: approx. 100msec). The powerful FMS services open up a wide
range of applications and provide a high degree of flexibility. FMS is also suit-
able for extensive communication tasks.

2.2 RS485 transmission technology
Transmission takes place according to the RS485 standard. It covers all areas
in which a high transmission speed and simple, cost-effective installation are
required. A shielded twisted copper cable with one conductor pair is used.
The bus structure permits addition and removal of stations or step-by-step
commissioning of the system without affecting the other stations. Later expan-
sions have no influence on the stations which are already in operation.
Transmission speeds between 9.6 kbit/sec and 12 Mbit/sec are available. One
uniform transmission speed is selected for all devices on the bus when the
system is commissioned.
Basic features of the RS485 transmission technology
Installation
tips All devices are connected in a bus structure (line). Up to 32 stations (master or slaves) can be linked up in one segment.
The bus is terminated by an active bus terminator at the start and end of each
segment. Both bus terminators must always be powered, to ensure fault-free
operation.
If there are more than 32 users, repeaters must be used to link up the individu-
al bus segments.
Network topology linear bus, active bus termination at both ends,
stub cables are only permissible for baud rates
≤1.5 Mbit/sec.
Medium shielded twisted-pair cable
Number of stations 32 stations in each segment without repeater (line amplifier).
With repeaters, this can be expanded to 126.
Connector preferably 9-pin sub-D connector

2 Profibus description
Cable length The maximum cable length depends on the transmission speed. The cable
length specified can be extended by using repeaters. It is recommended not
to connect more than 3 repeaters in series.
Range based on transmission speed
Cable data These cable length specifications refer to the cable type described below:
Characteristic impedance: 135 — 165 Ω
Capacitance per unit length: < 30 pf/m
Loop resistance: 110 Ω/km
Core dia.: 0.64 mm
Core cross-section: > 0.34 mm²
It is preferable to use a 9-pin sub-D connector for PROFIBUS networks incor-
porating RS485 transmission technology. The pin assignment at the connector
and the wiring are shown at the end of this chapter.
PROFIBUS cables and connectors are supplied by several manufacturers.
Please refer to the PROFIBUS product catalog (www.profibus.com) for types
and addresses of suppliers.
When connecting up the devices, make sure that the data lines are not re-
versed. It is absolutely essential to use shielded data lines. The braided shield
and the screen foil underneath (if present) should be connected to the protec-
tive earth on both sides, and with good conductivity. Furthermore, the data
lines should be routed separately from all high-voltage cables, as far as this is
possible.
As a suitable cable we recommend the following type from Siemens:

2.3 PROFIBUS DP
PROFIBUS DP is designed for high-speed data exchange at the field level.
The central control devices, PLC/PC for instance, communicate through a fast
serial connection with distributed field devices such as I/O, paperless
recorders and controllers. Data exchange with these distributed devices is
mainly cyclic. The communication functions required for this are defined by
the basic PROFIBUS DP functions in accordance with EN 50 170.
Basic
functions The central controller (master) reads the input information cyclically from the slaves and writes the output information cyclically to the slaves. The bus cycle
time must be shorter than the program cycle time of the central PLC. In addi-
tion to cyclic user data transmission, PROFIBUS DP provides powerful func-
tions for diagnostics and commissioning.
Transmission technology:
• RS485 twisted pair
• Baud rates from 9.6 kbit/sec up to 12 Mbit/sec
Bus access:
• Master and slave devices, max. 126 users on one bus
Communication:
• Peer-to-peer (user data communication)
• Cyclic master-slave user data communication
Operating states:
• Operate: Cyclic transmission of input and output data
• Clear: Inputs are read, outputs remain in secure state
• Stop: Only master-master data transfer is possible
Synchronization:
• Sync mode: not supported by the recorder
• Freeze mode: not supported by the recorder
Functionality:
• Cyclic user data transfer between DP master and DP slave(s)
• Dynamic activation or deactivation of individual DP slaves
• Checking the configuration of the DP slaves
• Address assignment for the DP slaves via the bus
• Configuration of the DP master via the bus
• maximum of 246 bytes input/output data for each DP slave
Protective functions:
• Address monitoring for the DP slaves
• Access protection for inputs/outputs of the DP slaves
• Monitoring of user data communication with adjustable monitoring timer
in the master
Device types:
• DP master Class 2, e. g. programming/project design devices
• DP master Class 1, e. g. central automation devices such as PLC, PC…
• DP slave e. g. devices with binary or analog inputs/outputs, controllers,
recorders...

Cyclic
data
transmission
The data transmission between the master and the DP slaves is carried out by
the master in a defined, recurring order. When configuring the bus system, the
user defines the assignment of a DP slave to the master. It is also defined
which DP slaves are to be included in, or excluded from, the cyclic user data
communication.
Data transmission between the master and the DP slaves is divided into three
phases: parameterization, configuration and data transfer. Before a DP slave
enters the data transfer phase, the master checks in the parameterization and
configuration phase whether the planned configuration matches the actual de-
vice configuration. In the course of this check, the device type, format and
length information, as well as the number of inputs and outputs must agree.
These checks provide the user with reliable protection against parameteriza-
tion errors. In addition to the user data transfer, which is performed automati-
cally by the master, new parameterization data can be sent to the DP slaves at
the request of the user.

3 Configuring a PROFIBUS system
3.1 GSD files
Device base data (GSD) enable open project design.
PROFIBUS devices have different features. They differ with respect to the
available functionality (e. g. number of I/O signals, diagnostic messages) or
possible bus parameters, such as baud rate and time monitoring. These pa-
rameters vary individually for each device type and manufacturer. In order to
obtain simple Plug & Play configuration for PROFIBUS, the characteristic de-
vice features are defined in an electronic device data sheet (Device Data Base
File, GSD file). The standardized GSD files expand open communication up to
the operator level. By means of the project design tool, which is based on the
GSD files, devices from different manufacturers can be integrated into a bus
system, simply and user-friendly. The GSD files provide a clear and compre-
hensive description of a device type in a precisely defined format. GSD files
are prepared according to the application. The defined data format permits the
project design system to simply read in the GSD files of any PROFIBUS DP
device and automatically use this information when configuring the bus sys-
tem. Already during the project design phase, the project design system can
automatically perform checks for input errors and the consistency of data en-
tered in relation to the entire system.
The GSD files are divided into three sections.
•General specifications
This section contains information on manufacturer and device names,
hardware and software release states, baud rates supported and the
possible time intervals for monitoring times.
•DP master-related specifications
This section contains all the parameters related to DP-master devices only,
such as the maximum number of DP slaves that can be connected, or
upload and download options. This section is not available for slave
devices.
•DP-slave related specifications
This section contains all slave-related specifications, such as the number
and type of the I/O channels, specification of diagnostic texts and
information on the consistency of I/O data.
The GSD format is designed for flexibility. It contains lists, such as the baud
rates supported by the device, as well as the possibility of describing the mod-
ules available in a modular device.

3.2 Configuration procedure
Plug & Play To simplify the configuration of the PROFIBUS system, the master (PLC) is
configured using the PROFIBUS configurator and the GSD files, or in the PLC
through the hardware configurator.
Configuration steps:
- Create GSD file by using the GSD generator
- Load GSD files of the PROFIBUS slaves into the PROFIBUS network
configuration software
- Perform configuration
- Load configuration into the system (e.g. PLC)
The GSD file The characteristic device features of a PROFIBUS slave are specified by the
manufacturer, clearly and comprehensively in a precisely defined format, in the
GSD file (Device Data Base File).
The PROFIBUS
configurator /
hardware
configurator
(PLC)
This software can read in the GSD files for PROFIBUS DP devices of any man-
ufacturer and integrate them for the configuration of the bus system.
Already in the project design phase, the PROFIBUS configurator automatically
checks the files that have been entered for errors in system consistency.
The result of the configuration is read into the master (PLC).

3.3 The GSD generator
3.3.1 General
GSD files for recorders with a PROFIBUS interface are generated by the user
with the aid of the GSD generator.
The recorders with a PROFIBUS interface can send or receive a large variety
of variables (parameters). Since, however, in most applications, only a portion
of these variables will be sent via PROFIBUS, the GSD generator makes a se-
lection of these variables.
After selection of the device, all available variables are shown in the “Parame-
ters“ window. Only after these have been copied to the “Input” or “Output”
window will they later be contained in the GSD file for processing or pre-
processing by the master (PLC).
