1. Welcome to
ServiceLab!
1.1 ServiceLab Application Range
You have acquired user-friendly troubleshooting software that provides a large range of functions and
options for your data acquisition tasks.
With ServiceLab it is easy to perform acquisition, visualization and evaluation of process data from
SIMATIC S7 (300/400), SIMATIC S5 or any analog data source. Even complex measuring tasks can be
solved with ServiceLab : fast and without external programming expenditure.
ServiceLab is particularly suitable for the following applications:
Real-Time Visualization of process data
Long-term measurement with user-friendly evaluation without paper consumption
Limit value monitoring of process signals
Acquisition of machine data
Recognition and analysis of errors and disturbances
Support with commissioning and service
Use at training courses
Checking the transient response of controllers
With this demo version a connection between PC/PG and SIMATIC/SIPART is possible, however limited
to one channel.
Communication with SIMATIC S5 and SIPART is via the serial interface of the PC’s/PG’s.
To access a SIMATIC S5 from a PC you need a specific cable that makes the conversion from R-S232 to
TTY. You do not need additional hardware. Communication with SIMATIC S7 is via the MPI/PROFIBUS
interface. To access a SIMATIC S7 from a PC/Notebook you need a PCI card (e.g. CP 5611), PCMCIA
card (e.g. CP 5511) or a PC adapter (RS232/MPI).
Due to the high degree of flexibility during the acquisition and evaluation of process data, ServiceLab is the
ideal aid for service, start-up and plant/equipment visualization.
In the next chapter you’ll find a short introduction to the ServiceLab operations. Some typical applications
for ServiceLab are also shown. In just a few minutes you can perform your first own experiment setup!

1.2 ServiceLab Worksheet
The experiment set-up and the process flow are presented in ServiceLab by a worksheet. This consists of
modules, which are interlinked over data channels. Each module fulfils a certain task, and the data channels
symbolize the data flow.
The example shows an experiment setup, in which a process variable is read from a SIMATIC, indicated in
a Recorder and a Digital Meter module, and stored on hard disc or floppy disc.
Chapter 1.4.2 describes in detail how the modules are parameterised.

1.4 The 9 Most Important Operating Instructions
1.4.1 How to Add a New Module to the Worksheet
At the left-hand side of the ServiceLab screen you can see the Module Bar.
It contains icons, which represent the most important modules available for an experiment set-up. There are
two possibilities to select a module. You can either click with the left mouse key on the appropriate symbol
in the module bar, or you select it from the Module Bar on the top left side of the ServiceLab worksheet.
1.4.2 Parameterising a Module
In order to change the settings of a module, doubleclick with the left mouse key on a module and a
parameterising window of the module will open. Here, various adjustments can be made to the module e.g.
you can select the number of channels.
Click with the left mouse key on the plus or minus bottom in order to add or remove channels. You can
adjust the settings for the individual channels by selecting the appropriate channel in the bar (click with the
left mouse key on the symbol). The corresponding channel settings will then change.
1.4.3 Linking Modules
You can connect two modules together by a click on the output “O” of the first module. The pointer
becomes a hand with a plug. Move the plug over the input “I” of the second module, followed by another
click with the left mouse key. The two modules will be connected automatically.
1.4.4 Deleting a Module
Double click with the right mouse key on the module, then choose “Delete Module”.
1.4.5 Deleting a Data Channel
Two clicks on the data channel with the right mouse key (not a doubleclick!).

ServiceLab
1.4.6 Definition of the Global Measuring Parameters
Click with the left mouse key on the shown icon, in the Function Bar. Then you can adjust the global
measuring parameters (e.g. the sampling rate)
1.4.7 Starting the Experiment
Click with the left mouse key on the shown icon in the Function Bar.
1.4.8 Stopping the Experiment
Click with the left mouse key on the shown icon in the Function Bar.
1.4.9 Help
ServiceLab is designed to be user-friendly. It has a logical structure that is to a large extent self-
explanatory.
Nevertheless, if you wish, you can at any time request detailed information about current developments.
You can call the “Text Assistant” by clicking in a dialogue box on the main menu bar under “Help”, by
clicking on the “question mark” in the Function Bar or by pressing the function key F1.

ServiceLab
1.5 Function Bar
ServiceLab Function Bar
1.5.1 Purpose of the function bar
The Function Bar below is the main menu line at the top margin of the ServiceLab window. The icons in
this bar symbolize menu instructions that are needed particularly frequently by a simple Mouse click you
can call these functions, without having to open the menus themselves. This procedure is more convenient
than (from the identical function) calling the appropriate instructions over the Menu Bar.
1.5.2 Meaning of the Function Bar Icons
The Function Bar configuration is fixed by the program. Therefore you cannot change this configuration by
removing or adding any icons.
The following table gives an overview of the icons and the menu commands that they represent.

2. Creating your First ServiceLab Worksheet
After learning about the basic elements and functions of ServiceLab in chapter 1, you surely now will want
to accomplish your first experiment. If you follow these instructions, you will create your first worksheet in
few minutes!
Double click with the left mouse key on the ServiceLab program icon. The main window of ServiceLab will
open with the Menu Bar at the upper edge, the Function Bar appears below and the Module Bar at the
left-hand side of the window. If you press the key F1, you will call the on-line assistance, that will give you
advice at any time for any situation. In this case you will receive an overview of the auxiliary functions
available in ServiceLab .
The Module Bar, at the left of the ServiceLab window, displays a selection of frequently required modules
in icon form.
Look for the accompanying icon in the Module Bar. It represents a Generator module. If you
click with the left mouse key on this icon, a dialog box appears. Select from here the option
“Without Modulation”.
Similarly, Click with the left mouse key on the icon Recorder in the Module Bar. An additional
icon at the lower edge of screen appears.
By these actions you have already produced two modules (Generator and Recorder). So that data can be
exchanged between these two modules, they must be connected by a Data Channel.
Move the mouse pointer on the Recorder module symbol (on the worksheet). There the mouse arrow is
transformed into a cross.
Press now the left mouse key and move the module (while still pressing mouse key) against the Generator,
until the output (O) and input symbols (I) of the two modules touch.
When you release the mouse key, ServiceLab connects the two modules automatically and provides for
the correct arrangement of the Data Channel. (It is also possible to connect the modules without moving
them: see in addition the section “Module Connection” on page 6).
The Data Channel is now created!
10
ServiceLab
Before you start the experiment, you must pre-set the used modules:
Click on the Function Bar, on the icon for Experiment Setup. A dialogue box appears, in which
you can adjust the Global Experiment Set-up. Please choose a sampling rate of 50ms and a
block size of 1.
Double click on the Generator module on the worksheet. Again a dialogue box appears, in which
the initial values of the Generator can be adjusted. Select a frequency of 0,5 Hz per second and
a sine curve.
11
ServiceLab
In the same way you can set parameters for the Recorder. Set the maximum display time to 20
seconds and display from -5,0 to 5.0 V.
The visualization module graphically displays the complete experiment set-up or measurement procedure.
This happens in a separate window. After placing a module symbol on the worksheet, this window is still
closed and is represented by an icon at the lower edge of screen. If a measuring procedure begins and you
would like to activate visualization, you must just "open" the window.To do this there are two possible
procedures. For both of these the left mouse key is used:
Click on this icon on the Function Bar (it stands for the command „show all display windows“
from the view menu),
or double-click on the icon Recorder at the lower edge of window screen. The Recorder window
opens and you can now observe, on its screen, the display of the signal produced by the Generator
module.
You can now start the experiment!
Click with the left mouse key on the shown icon in the Function Bar. Thereby you start the
experiment procedure, and after a short time the Generator Module produces a signal.
By clicking on this icon in the Function Bar with the left mouse key you can interrupt the measuring
procedure. With a subsequent click you can cause it to continue.
12
ServiceLab
Click with the left mouse key on the shown icon in the Function Bar. Thereby you terminate the
experiment procedure.
If you cannot see the Recorder module symbol (on the worksheet) because it is covered by the window,
then...
Shift the window, by clicking the left mouse key on the title border of the window and moving with
the mouse key pressed to the desired place, or...
Close it, by clicking with the left mouse key the smaller icon (that is the arrow directed downward in
the right upper corner of the window framework).
Doubleclick then with the right mouse key on the Recorder symbol (on the worksheet). If you press the ok
key from the following safety inquiry, the Recorder module and the connection to the Generator from the
worksheet are deleted.
Click with the left mouse key in the submenu “Module/ Display / Bar graph”. The module is placed
on the working surface. At the lower edge of the screen you see in addition the icon for the
associated window.
Connect the entrance of the module symbol - as above described - with the exit of the Generator module.
Open the window by one double-click with the left mouse key, on the icon at the lower edge of screen and
…
You restart the measurement. Here is not necessary to parameterise the Bar Graph, since the
adjusted basic values fit for this example.
The values of the Generator signals are visualized after a short time in the Bar Graph window.
Stop the experiment with the help of the icon in the Function Bar.
Click with the left mouse key on the icon of the Digital Meter module in the Module Bar. The
module is placed on the worksheet beside the Bar Graph module; at the lower edge of screen you
see the icon for the Digital Meter.
Move the Digital Meter on the worksheet, by clicking it with the left mouse key and moving with pressed
mouse key to another place, for example under the Bar Graph module symbol. In order to also attach the
Digital Meter module to the Generator, it is enough "to tap" the existing connection between Generator
and Bar Graph.
13
ServiceLab
Click for this with the left mouse key on any place on the data channel, which connects the Generator with
the Bar Graph module. The mouse pointer now has now the form of a hand with a plug. Lead the plug into
the input of the Digital Meter module (small box at the left hand side of the module symbol, named "I"), and
click again there with the left mouse key. The inserted autorouting function provides for the correct and
clear shifting of the new data channel.
You can now - as above described - start, interrupt and continue the experiment procedure, the window of
the Digital Meter by clicking on the icons at the lower edge of screen to open and the colour of its display
area to change. (Modules > Display > Bar Graph)
(In case ServiceLab does not react to your clicks ask yourself: ”Did I first terminate the current
experiment?” Only then can changes to the experiment set-up be done.)
The Demo Version contains a set of worksheet for applications, which are described in chapter 3. You can
load, run and modify all these examples.
In order to load stored worksheets, click with the left mouse key on the shown icon in the
Function Bar. With this you can open an existing experiment set-up.

3. Typical applications
In this chapter we show you the different possibilities as to how one can quickly and simply acquire,
visualize, analyse and document the signals from SIMATIC S7 and SIMATIC. Importance has been given
to including as much information as possible for solving existing experimental tasks.
In the Demo Version only single-channel communication with SIMATIC and/or SIPART is possible. In
addition, in the Demo Version the store functions of Experiment data and Experiment set-up are
deactivated. Some modules, which are present in the Demo Version, are not contained in ServiceLab
Basic Version (6ES5 886-8SL11); see for this the “List of Modules” on page 35.
In most of the following examples, Process Signals are simulated by a Generator function.
Many of the examples are already included in ServiceLab 7.0. You can load, modify and perform the
respective measurement set-up in ServiceLab. Storing a measurement set-up is not possible in the Demo
Version.

which milk is transported and processed. The cleaning consists of several stages: pre-rinsing, caustic
solution, rinsing, acid and rinsing. But the fully automatic cleaning did not succeed in reducing the number of
bacteria in the plant to the legal limit. The cause of this was that construction units (pumps etc..) in the plant
were in the course of the time incorrectly replaced so the parameters (pressure, temperature and
conductance) had changed for the plant. However, since they had not been re-co-ordinated, the cleaning
did not any longer work accurately. This was, among other things, a reason why the workers in the dairy, to
a large extent, serviced the plant manually.
ServiceLab should be used to produce a comprehensive overview of all the experiment values of the plant
without a large time and, above all, personnel expenditure.
Solution:
All the cleaning equipment parameters were noted during the complete purification process (approx. 40
min). In addition a laptop was attached to the PG interface of the SIMATIC S5-115 and the program
ServiceLab was started by Siemens. The illustration shows a cutout from the connection worksheet, which
was developed for the problem represented above.

The complete connection worksheet contains four similar developed circuits (SYS 1 to 4), i.e. each circuit
system corresponds to a worksheet.
Worksheet Explanation:
Transducers supply the temperature, flow rate and conductance data over the DDE connection to the
program ServiceLab (DDE modules). Subsequently, the tension signals must be converted by scaling to
the appropriate values (module Scaling SYS 1). Afterwards the data are given by continuous curves as a
function of time on the monitor (module P3-sys 1). Additionally, after separating the data set (module
September SYS 1) the reduced data are stored again on the given monitor (module P24-sys 1) and on the
hard disk of the laptop (module f-sys 1).
The fourth DDE connection (module circle SYS 1) monitors event-dependent actions (module A-sys 1), i.e.
with a certain condition (e.g. switching on the cleaning equipment) the program ServiceLab is started, or a
list with the values is printed out.
Solution:
ServiceLab is used to receive a comprehensive overview of all measured values of the plant without large
time and personnel expenditure.
Comment:
This worksheet was developed using an earlier version of ServiceLab, which the module SIMATIC S5 was
not yet contained. For communication with the SIMATIC in place of its the module DDE connection was
used.

3.15 Real Life Usage example: Documentation of
parameters during a test run
Task:
The company Rheinelektra technology GmbH of Aalen manufactures, amongst other things, electrical
controls for filtration plants (e.g. for fruit juice concentrates, protein or industrial water) for the company
Membraflow Filter Systems, Aalen. As SPS serves the SIMATIC S5, the task of the company Rheinelektra
is it to develop and test the electrical control for these filter systems. A metrology record of all parameters
is to be provided, which the customer receives with the final inspection.
Solution:
In the test run, the entire plant is gradually advanced to the intended performance. At the same time the
ServiceLab program seizes and plots the individual measured values. Thus one sees the transient
response of the plant and can intervene in the process at any time. The following connection worksheet
represents only an excerpt of the actually used connection worksheet with altogether 11 DDE connections
and a TTL Pulse Generator.

Worksheet explanation:
Transducers (pressure, temperature, etc.) supply the data over the DDE connection to the ServiceLab
program (DDE modules). Subsequently, the voltage levels are converted into appropriate values for
pressure, temperature, etc. (Scaling modules) and as actual values into digital displays. Additionally every
31
ServiceLab
five minutes (T TL Pulse Generator module + Release module) the measured values are stored in a list
(List Module) and printed out if necessary.
Solution:
The use of ServiceLab led to a saving of time, with start-up and/or test run.
Comment:
This worksheet was developed with an earlier version from ServiceLab, which did not contain the
SIMATIC S5 module. In place of this module, for communication with the SIMATIC, the module DDE
connection was used.

4.2. Coupling values SIMATIC S7/S5/SIPART
4.2.1. Maximum Number of Experiment Values
Over the modules SIMATIC S5/S7 and SIPART we can acquire a maximum of 256 process values at the
same time.
4.2.2. Maximum Sampling Rate
SIPART Module
An approximate value for the minimum sampling rate-recorded value can be computed using the following
formula:
Number of SIPART modules in the worksheet * 30ms
+ Number of recording channels in the worksheet * 25ms.
SIMATIC S5 Module
It is very difficult to obtain an exact estimation of minimum sampling rate recorded in a process with the
module SIMATIC S5 since this is dependent on several parameters. Among other things there are the
number of SIMATIC-S5-Modules in the worksheet, the number of collection channels, the kind of the
process (binary value, 8-bit value, 16-bit-value) and the complexity of the worksheet. Therefore only a few
examples are specified here:
Recording from
Minimum sampling period per channel in ms
1 process factor
8 Binary values within a byte
8 entrance bytes
16 data items
up to 75
Approx. 500
Approx. 600
Approx. 1500
SIMATIC S7 module
It is very difficult to obtain an exact estimation of minimum sampling rate recorded in a process with the
SIMAT IC S7 Module, since this is dependent on several parameters. Nevertheless sum-sampling rates of
40 cycles per second (corresponding to a sampling period of 25 ms) can be achieved and more with
appropriate hardware.
Measuring cards
ServiceLab can be operated with different manufacturer Measuring Cards, thereby sum sampling rate of
200 k Samples/s and more possible (the sum sampling rate depends on the efficiency of the used
measuring card).
