Introduction
1.1
General
The PROFIBUS Tester 4 is a powerful tool that allows full testing of the bus
physics and bus communication on PROFIBUS DP segments.
Using the integrated master simulator, you can also test the bus physics if the
PLC is currently not in operation, or individually check “suspicious” bus
stations.
The tool is powered either through an external AC adapter, by direct
connection to 24 VDC or through an optional portable power supply unit.
1.2
Test Functions
The PROFIBUS Tester 4 automatically detects the baud rate or open circuit
voltage as soon as you connect it to a PROFIBUS DP segment.
You can then choose between two modes of operation for bus testing
depending on if you run it in stand-alone mode, or connect the PROFIBUS
Tester 4 to a PC or notebook. If required the master simulator can be enabled
in both modes if no other master is active.
1.2.1
Stand-alone mode of operation
In the stand-alone mode three test functions with simultaneous analysis of bus
physics and bus communication are available:
1. The Live Status shows the bus status and the details of the analysis
in real-time on the display.
2. To evaluate the bus health up to ten Quick Tests can be executed,
stored internally and imported by the PC software then.
3. To locate the causes of sporadic bus faults the long-term Trend logs
data for up to 41 days and stores them internally for later import by the
PC software.

1.2.2
Introduction
PC mode of operation
The PC software provides many additional features for performing, analyzing
and managing bus tests. Quick Tests and Trends stored in the tool can be
imported.
In the PC mode four main functions are available. Two of them provide
complex functionality that only experts need and that are accessed separately
from the standard functionality.
Standard functions:
1. The Network Status is a collection of information and test data
relating to a PROFIBUS network. It provides the basis for a
comprehensive evaluation of the bus health.

2. If sporadic faults occur in a PROFIBUS installation, the quality indexes
and critical protocol events should be monitored with the long-term
Trend over a prolonged period to locate the causes of bus problems.
Expert functions:
3. The function Frames enables the classic frame analysis.
4. The Oscilloscope permits the detail analysis of signal waveforms.

Fieldbus Shield Digital Leakage Current Clamp
When routing PROFIBUS cables in high-interference environments,
electromagnetic interference can affect the signal quality. By measuring the
shield currents with the digital leakage current clamp, you can locate EMC
problem areas and take appropriate countermeasures. The digital leakage
current clamp is supplied in a handy case, including measuring cables. There
is also an empty compartment for the fieldbus shield digital leakage current
clamp in the carrying case of the BC-600-PB.

Service Interface for PROFIBUS DP
3.5.1
Connection Type D-sub
The D-sub service interface provides a PROFIBUS access point for testing if
the existing D-sub connectors have no service socket or if the bus stations are
connected via a terminal block. The service interface can power the
terminating resistor of the D-sub connector. You can thus use it as an active
bus termination at the beginning or end of the bus.
If the PLC allows dropping and adding bus stations on the live bus, you will
need this external bus termination to be able to exchange the first and last bus
stations without causing problems on the bus.
The compact unit is rail mounted like a terminal block and powered by an
external 24 VDC power supply. The package includes an 90° angled
PROFIBUS connector with a switchable terminating resistor.

Manual
Power Supply and Auto Power On
The tool is powered with 24 VDC either through the external AC adapter or by
using the single-ended cable for direct 24 VDC power supply. Both are
included in delivery.
Attention: Before being connected to the AC mains power, the
PROFIBUS Tester 4 and the AC adapter must be acclimated to room
temperature to avoid condensation. This may take up to 60 minutes.
The tool switches on automatically when you connect it to a power supply. The
display lights up and self-test starts.
Attention: When the tool is connected directly to 24 VDC, there is no
galvanic isolation to the external power supply. Insufficient potential
equalization between the power supply and the PROFIBUS will lead
to equalizing currents which can falsify the test results and, in the
worst case, even destroy the PROFIBUS Tester 4 and part of the bus
installation. In these cases, use of the supplied AC adapter is
mandatory for operating the PROFIBUS Tester 4.
On completion of initial setup, the PROFIBUS Tester 4 displays the following
dialog in English:
You can now select the desired display language. The following languages are
available: German, English, French, Italian, Polish and Spanish.

Manual
Software Installation
The “PROFIBUS Diagnostics Suite” PC software is provided on the included
CD-ROM. You need administrator privileges to install the software. If the CDROM does not start automatically when inserted, please run the “start.exe” file
in the main directory.
Future updates can be downloaded from our web site at industrial.softing.com.
Attention: The “PROFIBUS Diagnostic Suite” PC software also
includes the required USB driver. You therefore need to install the
software first before connecting the test tool to the PC or notebook.
The installation and basic use of the PC software is described in the separate
PROFIBUS Diagnostics Suite – Getting Started manual.
6.1
Connection to a PC
Use the included USB cable to connect the tool to a PC or notebook. Power is
also supplied from the USB interface.
Attention: It is recommended to connect the unit directly to a USB
port on the PC or notebook. When you use external USB hubs or
notebook docking stations for connection, problems can occur.

Warning notice for testing a live bus
Attention: When you connect a test tool, side effects on the
system under test are generally unavoidable. If the PROFIBUS is
already disturbed to a certain degree or if Simatic Diagnostic
Repeaters are used, the operation of the PROFIBUS might
nevertheless be affected occasionally. Compliance with the
connection notes is mandatory!

7.1.2
Connection to PROFIBUS
Connection types
There are several ways to connect a bus station to a PROFIBUS network:
•
•
Using connectors
o D-sub connectors, most of which have an integrated terminating
resistor and, optionally, an additional service socket
o M12 connectors for environments requiring increased IP ratings
o Special vendor-specific hybrid connectors; they are used in
combination with special cables to supply power via the bus
Using terminals for direct connection
Due to the typical daisy-chain topology, the connection points of the bus
stations are the only possible points for connecting the test tool in most cases.
7.1.3
Adapter cable
The PROFIBUS Tester 4 is supplied with the D-sub adapter cable BC-600-PBCB-DSUB-2 „Standard“ (light connector). For testing on live systems the
optional D-sub adapter cable BC-600-PB-CB-DSUB-2 is recommended. An
M12 adapter set is optionally available, see on page 9.
Attention: Use only the short original cables with special pin layout to
connect the unit to a PROFIBUS network. Do not cascade more than
two D-sub connectors with service sockets at the same time:
Fig. 11: Unallowed cascading of D-sub connectors
Active connection cables with integrated repeaters, such as Softing's BC-131PB, cannot be used for testing.
Softing

7.1.4
Manual
Strain relief
Attention: When you connect the PROFIBUS Tester 4, its weight can
place a high mechanical stress on the connectors and the bus
station. Ensure proper strain relief by using suitable supports, cable
ties, etc. When this is not possible, you need to select a different
connection point to avoid damage.
Fig. 12: Strain relief fittings
7.1.5
Test locations
The PROFIBUS Tester 4 can basically carry out tests anywhere on a physical
PROFIBUS segment. Please note that the use of repeaters creates separate
physical segments that each need to be measured individually.
For the best and most informative results, perform the tests at the beginning
and end of each physical segment. If these test results indicate problems that
cannot be clearly classified right away, you should carry out one or more
additional tests at the centre.

7.2
Connection to PROFIBUS
Simple Connection for Tests During System Shutdown
If all bus stations provide D-sub connectors with an additional service socket,
you can simply plug in the PROFIBUS Tester 4 at that socket (see figure
below). If a D-sub connector does not provide a service socket, you can plug
in the D-sub adapter cable underneath. The only thing you need to keep in
mind is that you should never cascade more than two D-sub connectors (see
page 17).
When using M12 connection technology, the M12 adapter cable is “looped”
into the bus. It is essential to ensure proper termination at the beginning and
end of the bus by using the terminating resistor provided with the M12 adapter
set.
Attention: All these simple connection types will divide the bus. You
therefore need to shut down the PLC and all the devices connected
to the PROFIBUS; in other words, you need to shut down the whole
installation.

Connection for Testing a Live Bus
To test a live PROFIBUS with the PROFIBUS Tester 4 during operation,
appropriate connection possibilities have to be provided. If no suitable
connection points are available in the existing installation, it is recommended
to install them during system shutdown. This will make future maintenance
work much easier.
Attention: When installing additional connection points, you divide the
bus. Before doing so, you therefore need to shut down the PLC and
all the devices connected to the PROFIBUS; in other words, you need
to shut down the whole installation.
Attention: For testing on live systems the optional D-sub adapter
cable BC-600-PB-CB-DSUB-1 with reduced influence on bus
operation is highly recommended! See page 9.

Master Simulator and Topology Scan
The master simulator allows checking the bus cabling and the station
addresses during installation and commissioning, when the PLC (master) is
not in operation yet. In addition, you can use this mode to check individual
“suspicious” bus stations that have been disconnected from the bus.
Softing
Page 23
Connection to PROFIBUS
Manual
The topology scan determines the sequence and distances of all passive bus
stations (slaves). This feature requires correct bus cabling, a very good signal
quality, and a connection point located directly at the beginning or end of the
bus.
Both features can only be used during shutdown of the installation. The D-sub
cable BC-600-PB-CB-DSUB-2 which is included in the standard scope of
supply must be used. As long as communication is detected on the bus, i.e. at
least one device is an active master, the functions are disabled. If necessary,
disconnect every single active device (PLC, MPI and, if necessary, diagnostic
repeaters) from the power supply or the bus. If an active device is at the end of
the bus you want to test, its PROFIBUS connector needs to be unplugged and
connected directly to the PROFIBUS Tester 4. The bus termination in the
device connector will then be powered by the PROFIBUS Tester 4.

Attention: Bus stations must only be disconnected from the power
supply or the bus during shutdown of the installation.
Attention: The two functions can be started also when the PROFIBUS
Tester 4 is disconnected from the bus. If you then connect the
PROFIBUS Tester 4 to a live bus despite the yellow bus status bar
indicated by the PC software, this can cause bus communication
problems or a shutdown of the installation.
7.4.1
Special case: Active devices at both ends of the bus
On the very rare occasion when there is an active device at each end of the
bus, do the following:
1. When using D-sub connection:
•
Additionally switch on the terminating resistor in the D-sub
connector of the last slave. The outgoing cable to the active
device at the bus end has to be connected to the outgoing
connector (marked with “OUT”, an outgoing arrow, or “A2/B2”).
Fig. 18: Checking the connection direction at the D-sub connector
2. When using M12 connection:
•
Softing
The cable from the bus start or test tool has to be connected to
the incoming M12 connector of the last slave. A bus termination is
required at the outgoing M12 connector of the last slave.

Trend function
Trend logging is used for detecting rare or sporadic faults over a prolonged
period of time. The function monitors both the bus physics and critical events
in the bus communication. The PROFIBUS Tester 4 can automatically test the
bus in stand-alone mode from within the control cabinet for up to 41 days. The
test data is stored in the tool. It can subsequently be imported by the
PROFIBUS Diagnostics Suite software application.
Before you start the function, choose a test interval. When you select “Auto”
the tool automatically determines the optimum interval. The Trend Test runs
until manually stopped with the “x” key.
Fig. 27: Trend running for 23 h and 52 min.
The test is aborted automatically when the power supply is interrupted (all data
logged so far is retained in memory) or when the maximum logging time of 999
hours and 59 minutes is reached.

Data Import into the PC
Data Import into the PC
Quick Tests and Trend logs stored in the test tool can be imported into the PC
software. To do this, start the PROFIBUS Diagnostics Suite. If a PROFIBUS
Tester is connected to the PC via USB and contains stored test data, an
additional “Import Test Data from Tool” dialog box appears automatically.
Fig. 28: Importing test data
For ALL the stored data, you need to fully select the action to be performed,
the network/project, and the test location to which you want to store the data.
The default action “Import & Delete“ deletes the test data in the tool after the
import is complete. This frees the allocated memory locations for new tests.
The imported Quick Tests and Trend logs are fully compatible with the test
data that can be acquired using the PC software.

Неисправности Profibus и их устранение

Если вы программист, то вы знаете что такое Profibus, если нет, то пора узнать, тем более если у вас появились такие проблемы.

Profibus (с англ. Process Field Bus — шина полевого уровня) — открытая промышленная сеть, прототип которой был разработан компанией Siemens для своих промышленных контроллеров Simatic. На основе этого прототипа Организация пользователей Profibus разработала международные стандарты, принятые затем некоторыми национальными комитетами по стандартизации.

Ну или простыми словами, если вы видели фиолетовый провод с двумя проводами, то это он 😉

Profibus (с англ. Process Field Bus — шина полевого уровня)

Существует несколько вариантов, которые могут произойти:

Короткое замыкание на линиях А-В

Короткое замыкание экрана А/В

Отсутствующая или избыточная терминация

Пути решения проблемы

Перепутанные провода

У Profibus коннекторов в разъем А подключается зеленый провод, в разъем В подключается красный провод. Также правильно, чтобы было подключение А1,В1 — вход, а А2,В2 — выход.

Правильное подключение Profibus

Как исправить перепутанные провода. Просто проверить подключение.

Полезные советы

Разрывы проводов

Кабель Profibus может быть как многожильным, так и монолитным. Как и у обычных проводов

P.S. Многожильный кабель очень неудобно вставлять в коннекторы.

Из чего состоит кабель Profibus

Монолит медный кабель может через время сломаться. Часто при разделке кабеля можно повредить медь и при укладке в коннектор бывало кабель ломался.

Полезные советы

Короткое замыкание на линиях А-В — Короткое замыкание экрана А/В

Начнем с понятия КЗ.

Короткое замыкание (КЗ) — электрическое соединение двух точек электрической цепи с различными значениями потенциала, не предусмотренное конструкцией устройства и нарушающее его нормальную работу.

При замыкании линий A-B, или замыкании одной из линий на экран происходит перезагрузка контроллера, так и выход одной линии по сети из строя.

Полезные советы.

Если у вас есть схема сети профибас, то в онлайне Hardware Step 7 можно увидеть какие станции отключены. Сопоставив со схемой можно определить в каком месте проблема.

Также можно также определить номера станций, которые активны, а которые нет используя «Set PG/PC interface». Во вкладке «Properties» можно увидеть с галочкой — активные модули, а модули неактивные будут просто без галочки, пустое белое поле.

Длина сегмента Profibus

Максимальная длина сети Profibus зависит от скорости. Скорость передачи и соответствующая длинна сегмента

Таблица зависимости скорости Profibus от длины сегмента

Соответственно, чтобы сигнал доходил без потерь необходимо соблюдать данные скорости и метраж.

Полезные советы.

Если в процессе работы у вас теряются части данных, то необходимо в Hardware SIEMENS поменять скорость, на более низкую.

Также для усиления сигнала можно поставить Repeater. Repeater служит для усиления сигналов данных, передаваемых по кабелям шины, и для объединения сегментов шины.

Отсутствующая или избыточная терминация

Тут все просто, необходимо проверить терминальные резисторы на коннекторах. Если расстояние маленькое, то контроллеру все равно на резисторы, однако при больших расстояниях теряется сигнал.

Полезные советы

Главное правило — начальные и конечные точки — не забудь включить резистор. Волновое сопротивление кабеля должно быть равно нагрузочному резистору в начале и в конце сегмента.

Имеем один кусок кабеля, на концах которого висят два приёмника-передатчика, эти величины должны друг другу соответствовать. Однако на деле их количество может быть значительно больше двух, что изменит волновое сопротивление кабеля. Поэтому нельзя в общем случае гарантировать равенство волнового сопротивления и нагрузочного резистора, а можно лишь пытаться обеспечить примерное их соответствие, что и делается установкой 220 Ом.

Про отсутствующую терминацию я более подробно расскажу в следующей статье.

Диагностика сети PROFIBUS Indu-Sol

Диагностика сети PROFIBUS Indu-Sol
PROFIBUS (Process Field Bus) – это промышленная сеть полевого уровня, отвечает требованиям европейских норм EN5017-2 и международного стандарта IEC 61158. Данный стандарт используется для организации связи между программируемыми контроллерами и станциями распределенного ввода-вывода, а также устройствами человеко-машинного интерфейса и другими приборами полевого уровня. PROFIBUS позволяет выполнять конфигурирование, диагностирование и отладку системы автоматизации.

PROFIBUS поддерживает следующие протоколы передачи:
– PROFIBUS-DP (Profibus for Decentralized Peripherals – «Profibus для децентрализованной периферии») – протокол ориентирован на организацию связи между контроллерами и устройствами распределенного ввода-вывода, а также другими приборами полевого уровня. Он обеспечивает наиболее быстрый циклический обмен небольшими объемами данных.
– PROFIBUS-FMS (Fieldbus Message Specification – спецификация сообщений шины полевого уровня) – протокол для обмена данными между сетевыми контроллерами, контролерами и компьютерами на регистровом уровне. Предоставляет большую гибкость при передаче больших объемов данных, но проигрывает протоколу DP в популярности вследствие своей сложности.
PROFIBUS FMS и DP используют один и тот же физический уровень, основанный на интерфейсе RS-485 и могут работать в общей сети.
– PROFIBUS-PA (Profibus for Process Automation – «для автоматизации технологических процессов») – протокол использует физический уровень на основе стандарта IEC 1158-2, который обеспечивает питание всех сетевых компонентов через экранированную витую пару и не совместим с RS-485. Подключение к сети PROFIBUS-DP осуществляется через модули сопряжения DP/PA Coupler или блоки DP/PA Link. Особенностью PROFIBUS-PA является возможность работы во взрывоопасной зоне.

Особые требования предъявлены к сетевому кабелю. Он имеет волновое сопротивление от 135 до 165 Ом при погонной емкости не более 30 пФ/м, площадь поперечного сечения проводников более 0,34 кв. мм. и погонное сопротивление не более 110 Ом/км. Кабель должен иметь одну или две витые пары с медным экраном в виде оплетки или фольги. (см. Каталог Продукции)

В местах соединений для шины PROFIBUS рекомендуется разъемы D-sub (DB-9) с 9-ю контактами. При необходимости иметь степень защиты IP65/67 рекомендуется использовать цилиндрический коннектор типа M12 (IEC 947-5-2)(см. Каталог Продукции).

Диагностика качества передачи данных в PROFIBUS

Хорошая скорость передачи, большая длина соединения и широкие возможности по обработке данных превращают PROFIBUS в одну из лучших шин, предназначенных для систем управления многими технологическими процессами и интенсивной обработки информации. Но чтобы обеспечить стабильность функционирования оборудования и производственного процесса в целом, состояние всех компонентов системы следует контролировать.

Причинами изменений в сети PROFIBUS могут быть запланированное и незапланированное вмешательство во время технического обслуживания или сборочных работ, а так же постоянное изнашивание (старение) электрокомпонентов и кабелей сети PROFIBUS.
Тестирование кабеля является обязательным условием для передачи чистого сигнала в сети PROFIBUS.

Тестер кабеля PROFtest II – идеальный инструмент для измерения характеристик кабеля, проверки правильной проводки во время ввода в эксплуатацию, ремонта и обслуживания сети PROFIBUS.

Прибор прост в обращении и с подробной текстовой индикацией на дисплее.

Все результаты измерений хранятся на устройстве и могут быть распечатаны через ПК в виде журнала.
