Preface

The SIMATIC automation system unites all the subsystems of an automation solu-tion under a uniform system architecture to form a homogenous whole from thefield level right up to process control

The Totally Integrated Automation (TIA) concept permits uniform handling of allautomation components using a single system platform and tools with uniformoperator interfaces These requirements are fulfilled by the SIMATIC automationsystem which provides uniformity for configuration programming data manage-ment and communication

This book describes the hardware components of the SIMATIC S7-400 automationsystem with standard controllers and the features provided for designing a distrib-uted control concept with PROFIBUS and PROFINET To permit communication withother automation systems the controllers offer integrated bus interfaces for multi-point interface (MPI) PROFIBUS and Industrial Ethernet

The STEP 7 Professional engineering software makes it possible to use the completefunctionality of the S7-400 controllers STEP 7 Professional is the common tool forhardware configuration generation of the user program and for program testingand diagnostics

STEP 7 Professional provides five languages for generation of the user programLadder logic (LAD) with a graphic representation similar to a circuit diagram func-tion block diagram (FBD) with a graphic representation based on electronic circuit-ry systems statement list (STL) with formulation of the control task as a list of com-mands at machine level a high-level Structured Control Language (SCL) similar toPascal and finally GRAPH as a sequencer with sequential processing of the userprogram

STEP 7 Professional supports testing of the user program by means of watch tablesfor monitoring control and forcing of tag values by representation of the programwith the current tag values during ongoing operation and by offline simulation ofthe programmable controller

This book describes the configuration programming and testing of the S7-400automation system with the STEP 7 Professional engineering software Version 11with Service Pack 4

1 Introduction


SIMATIC S7-400 is the modular control system for the medium and upper perfor-mance range (Fig 11) Different versions of the controllers allow the performanceto be matched to the respective application Depending on the requirements theprogrammable controller can be modularly expanded by inputoutput modules fordigital and analog signals in up to 21 racks with up to 18 modules

Further expansion with inputoutput modules is made possible by the distributedIO over PROFIBUS or PROFINET Special designs of these modules for increasedmechanical demands allow their installation directly on site on the machine orplant STEP 7 is used to configure and program the SIMATIC S7-400controllers Data

exchange between the controllers the distributed IO and the programming deviceis carried out over SIMATIC NET

111 SIMATIC S7-400 programmable controller

The most important components of an S7-400 programmable controller are shownin Fig 12

The CPU contains the operating system and the user program The user program isin the load memory of the CPU which can be expanded with a SIMATIC MemoryCard (MC) The user program is executed in the CPUs work memory The bus inter-faces present on the CPU establish the connection to other programmable control-lers

Signal modules (SM) are responsible for the connection to the controlled plantThese input and output modules are available for digital and analog signals

The function modules (FM) are signal-preprocessing ldquointelligentrdquo IO moduleswhich prepare signals coming from the process independent of the CPU and eitherreturn them directly to the process or make them available at the CPUs internalinterface Function modules are responsible for handling functions which the CPUcannot usually execute quickly enough such as counting pulses positioning orcontrolling drives

The CP modules allow data transfer in excess of the possibilities provided by thestandard interfaces on the CPU with regard to protocols and communication func-tions

In the case of an expansion the interface modules (IM) connect the central rackto a maximum of 21 expansion racks

Finally a power supply module provides the internal voltages required by the pro-grammable controller Load voltages or load currents must be provided via externalload current supply units

112 Overview of STEP 7 Professional V11

STEP 7 is the central automation tool for SIMATIC STEP 7 requires authorization (li-censing) and is executed on the current Microsoft Windows operating systemsConfiguration of an S7-400 controller is carried out in two views the Portal viewand the Project view

The Portal view is task-oriented

In the Start portal you can open an existing project create a new project or migratea project A ldquoprojectrdquo is a data structure containing all the programs and datarequired for your automation task The most important STEP 7 tools and functionscan be accessed from here via further portals (Fig 13)

b In the Devices amp networks portal you configure the programmable controllersie you position the modules in a rack and set their parameters

b In the PLC programming portal you create the user program in the form of indi-vidual sections referred to as ldquoblocksrdquo

b The Visualization portal provides the most important tools for configuration andsimulation of HMI systems using SIMATIC WinCC

b The Online amp Diagnostics portal allows you to connect the programming deviceonline to a CPU You can control the CPUs operating modes and transfer and testthe user program

The Project view is an object-oriented view with several windows whose contentschange depending on the current activity In the Device configuration the focalpoint is the working area with the device to be configured The Device view includesthe rack and the modules which have already been positioned (Fig 14) A furtherwindow ndash the inspector window ndash displays the properties of the selected module

25

and the task window provides support by means of the hardware catalog with theavailable modules The Network view allows networking between PLC and HMI sta-tions

When carrying out PLC programming you edit the selected block in the workingarea You are again shown the properties of the selected object in the inspector win-dow where you can adjust them In this case the task window contains the programelements catalog with the available program elements and statements The sameapplies to the processing of PLC tags or to online program testing using watchtables

And you always have a view of the project navigation This contains all objects of theSTEP 7 project You can therefore select an object at any time for example a pro-gram block or watch table and edit this object using the corresponding editorswhich start automatically when the object is opened

113 Five programming languages

You can select between five programming languages for the user program ladderlogic (LAD) function block diagram (FBD) statement list (STL) structured controllanguage (SCL) and sequential control (GRAPH)

Using the ladder logic you program the control task based on the circuit diagramOperations on binary signal states are represented by serial or parallel arrange-ment of contacts and coils (Fig 15) Complex functions such as arithmetic func-tions are represented by boxes which you arrange like contacts or coils in the ladderdiagram

Using the function block diagram you program the control task based on electroniccircuitry systems Binary operations are implemented by linking AND and OR func-tions and terminated by memory boxes (Fig 16) Complex boxes are used to handlethe operations on digital tags for example with arithmetic functions

Using the statement list you program the control task using a sequence of state-ments Every STL statement contains the specification of what has to be done andpossibly an operand with which the operation is executed STL is equally suitable

Fig 15 Example of representation in ladder logic

1 Introduction

26

for binary and digital operations and for programming complex open-loop controltasks (Fig 17)

Structured control language is particularly suitable for programming complex al-gorithms or for tasks in the area of data management The program is made up ofSCL statements which for example can be value assignments comparisons orcontrol statements (Fig 18)

Fig 16 Example of representation in function block diagram

Fig 17 Example of STL statements

Fig 18 Example of SCL statements


27

Using GRAPH you program a control task as a sequence control in which a se-quence of actions prevails The individual steps and branches are enabled by stepenabling conditions which can be programmed using LAD or FBD (Fig 19)

114 Execution of the user program

After the power supply has been switched on the control processor checks the con-sistency of the hardware and parameterizes the modules A startup program is thenexecuted once if present The startup program belongs to the user program whichyou produce Modules can be initialized for example by the startup program

The user program is usually divided into individual sections called ldquoblocksrdquo The or-ganization blocks (OB) represent the interface between operating system and userprogram The operating system calls an organization block for specific events andthe user program is then processed in it (Fig 110)

Function blocks (FB) and functions (FC) are available for structuring the programFunction blocks have a memory in which local tags are saved permanently func-tions do not have this memory

Program statements are available for calling function blocks and functions (start ofexecution) Each block call can be assigned inputs and outputs referred to as ldquoblockparametersrdquo During calling tags can be transferred with which the program in theblock is to work In this manner a block can be repeatedly called with a certain func-tion (eg addition of three tags) but with different parameters sets (eg for differ-ent calculations) (Fig 111)

Fig 19 Example of a GRAPH sequencer and step configuration

1 Introduction

28

The data of the user program is saved in data blocks (DB) Instance data blocks havea fixed assignment to a call of a function block and are the tag memory of the func-tion block Global data blocks contain data which is not assigned to any block

Following a restart the control processor updates the input and output signals inthe process images and calls the organization block OB 1 The main program ispresent here Structuring is also possible and recommended in the main programOnce the main program has been processed the control processor returns to theoperating system retains (for example) communication with the programming de-vice updates the input and output signals and then recommences with executionof the main program

Cyclic program execution is a feature of programmable logic controllers The userprogram is also executed if no actions are requested ldquofrom outsiderdquo eg if the con-trolled machine is not running This provides advantages when programming Forexample you program the ladder logic as if you were drawing a circuit diagram orprogram the function block diagram as if you were connecting electronic compo-nents Roughly speaking a programmable controller has a characteristic like forexample a contactor or relay control the many programmed operations are effec-tive quasi simultaneously ldquoin parallelrdquo

In addition to the cyclically executed main program it is possible to carry out inter-rupt-controlled program execution You must enable the corresponding interruptevent for this This can be a hardware interrupt such as a request from the con-trolled machine for a fast response or a cyclic interrupt in other words an eventwhich takes place at defined intervals

The control processor interrupts execution of the main program when an event oc-curs and calls the assigned interrupt program Once the interrupt program hasbeen executed the control processor continues execution of the main programfrom the point of interruption

115 Data management in the SIMATIC automation system

The automation data is present in various memory locations in the automationsystem First of all there is the programming device All automation data of aSTEP 7 project is saved on its hard disk Configuration and programming of theproject data with STEP 7 are carried out in the main memory of the programmingdevice (Fig 112)

The automation data on the hard disk is also referred to as the offline project dataOnce STEP 7 has appropriately compiled the automation data this can be down-loaded to a connected programmable controller The data downloaded into the usermemory of the CPU is known as the online project data

The user memory on the CPU is divided into two components The load memorycontains the complete user program including the configuration data and thework memory contains the executable user program with the current control dataThe load memory can be expanded by means of a plug-in memory card (MC) Dataretentivity ndash data values are not lost if there is a power failure ndash is achieved by usinga backup battery

The project data can be transferred between the programming device and CPU us-ing a FLASH memory card The normal case is an online connection for transfertesting and diagnostics

12 Introduction to STEP 7 Professional V11

121 Installing STEP 7

STEP 7 Professional V11 is executed onWindows XP Professional SP3 Win-dows 2003 Server R2 StdE SP2 Win-dows 7 (Professional Enterprise Ulti-mate) 32-bit and 64-bit and Windows2008 Server StdE SP2 operating sys-tems You require administrationrights in order to install STEP 7 and towork with STEP 7 you must at least belogged-on as a main user

The processor should at least be a Pentium M with 16 GHz or a comparable typeThe main memory should have a minimum size of 1 GB STEP 7 Professional re-quires approximately 2 GB free memory on system drive C on the hard disk

An interface module with an appropriate port is required on the programming de-vice for the online connection to the programmable controller The connection canbe established over MPI PROFIBUS or PROFINET (Ethernet) If you want to workwith a programming device with a memory card you need a corresponding EPROMprogramming module


31

Installation is carried out using the setup program startexe on the DVD Uninstal-lation of STEP 7 Professional is carried out as usual in Windows using the Softwareprogram in the Windows Control Panel

122 Automation License Manager

You require a license (user authorization) in order to use STEP 7 Licenses are man-aged by the Automation License Manager which is installed together with STEP 7Professional The license for STEP 7 Professional (license key) is provided on a USBflash drive You will be requested to provide authorization during installation if alicense key is not yet present on the hard disk You can also carry out the authori-zation following installation of STEP 7

The license key is stored on the hard disk in specially identified blocks To avoid un-intentional destruction of the license key you should observe the information forhandling license keys in the help text of the Automation License Manager If youlose the license key eg due to a defective hard disk you can revert to the trial li-cense delivered with STEP 7 which is valid for a limited duration

The Automation License Manager also manages the license keys of other SIMATICproducts such as STEP 7 V55 and WinCC When uninstalling STEP 7 V11 ensurethat the relevant license is also removed If the license is still needed you shouldback it up first

123 Starting STEP 7 Professional

You start STEP 7 Professional either using the Start button of Win-dows and Programs gt Siemens Automation gt TIA Portal V11 or bydouble-clicking on the icon on the Windows desktop The Totally In-tegrated Automation Portal (TIA Portal) is the framework in whichSTEP 7 is embedded TIA Portal may also contain other applicationsthat use the same database such as WinCC Professional

124 Portal view

Following initial starting-up STEP 7 Professional displays the Start portal A portalmakes available all functions and tools required for the respective range of tasks inthe portal view The scope of the portals as well as the range of functions and toolsdepends on the installed applications The Start portal of STEP 7 Professional per-mits selection of the following portals (Fig 113)

b In the Devices amp networks portal you can configure the hardware of the program-mable controller ie you select the hardware components position them andset their properties If several devices are networked you can define the connec-tions here

object with the right mouse button a window is opened with the currently select-able menu commands Underneath the main menu is the toolbar with the graphi-cally represented ldquomain functionsrdquo The main menu and the toolbar are alwayspresent in all editors

Using Options gt Settings in the main menu you can adapt the user interface Forexample under ldquoGeneralrdquo you can define the user interface language in whichSTEP 7 is used and the mnemonics (the representation of the operands ldquoIrdquo forinput in English or ldquoErdquo in German)

s Working window

In the center of the screen is the working window The contents of the working win-dow depend on the editor currently being used In the case of device configurationthe working window is divided in two the objects (stations and modules) are dis-played in graphic form in the top part and in tabular form in the bottom part Whenprogramming the PLC the top part of the working window contains the interfacedescription of the block and the bottom part the program You use the workingwindow to configure the hardware of the automation system generate the userprogram or configure the process screens for an HMI device

Fig 115 Components of Project view using example of block programming


35

d Inspector window

The inspector window underneath the working window shows the properties of theobjects marked in the latter records the sequence of actions and provides an over-view of the diagnostics status of the connected devices

During configuration or programming you set the object properties in the inspec-tor window for example the addresses and symbol names of inputs and outputsthe properties of the PROFINET interface tag data types or block attributes

f Project tree

The project tree window is displayed with the same content for all editors Its hier-archical structure contains all project data and the required editors With the proj-ect open it shows the folders for the PLC and HMI stations included in the projectand further subfolders within these folders eg for program blocks PLC tags andwatch tables with a PLC station or for example the process images and the HMItags in the case of an HMI station

A double-click on an object with project data automatically starts the associated ed-itor The project tree also includes editors such as Add new device Device configura-tion or Online amp diagnostics which you can start directly by means of a double-click

The lower section of the project tree contains a details view of those objects whichare present in the hierarchy underneath the object marked in the project tree

g Task window

To the right of the working window is the task window with the task cards This con-tains further objects for processing in the working window The contents of the taskwindow depend on the currently active editor In the case of the hardware configu-ration for example the hardware catalog with the available components is shownhere in the case of PLC programming the program elements catalog appears withonline amp diagnostics the online tools and with the visualization the library for theprocess image control and display elements

You can also call the libraries in this window Global libraries supplied with STEP 7or the project library in which you can save reusable objects such as programblocks templates for process images or control elements with special configura-tions

h Editor and status bar

At the bottom left of the Project view you can change to the Portal view In the mid-dle you can see the tabs of the open windows Clicking on a tab results in its contentsbeing displayed in the top level of the working window This makes it easy to changequickly between different window contents The far right of the status bar indicatesthe current status of project processing

1 Introduction

36

127 Adapting the user interface

The language of the user interface can be changed In the main menu select the sec-tion General under Options gt Settings In the User interface language drop-down listyou can select the desired language from the installed languages The texts of theuser interface are then immediately displayed in the new language You can also de-fine here how TIA Portal is to be displayed following the next restart

You can show or hide the displayed window using the menu item View You can al-ways change the size of windows by dragging on its edge with the mouse Windowscan be minimized into a symbol which appears in one of the navigation bars in theleft bottom or right margin of the screen

You can separate the working window completely from the Project view so that it isdisplayed as a separate window (symbol for Float in the title bar of the working win-dow) and also insert it again (symbol for Embed) Using the symbol for ldquoMaximizerdquoall other windows are closed and the working window is displayed in maximumsize The working window can be divided vertically or horizontally permitting youto view two working areas simultaneously

You can change the width of table columns by dragging with the cursor in the tableheader In the case of columns that are too narrow the entire content of the individ-ual cells will appear as a tooltip when the cursor is briefly hovered over the relevantfield

13 Editing a SIMATIC project

Fig 116 shows all tools and data which can be of importance in an automation taskOf prime importance is the Project which contains all the automation data requiredfor control and operation of the machine or plant The project data is roughly divid-ed into the data for the individual stations and the common project data which ap-plies to all stations in the project

A Station can be a controller (PLC station) an HMI device (HMI station) or a PC sta-tion A project can include several stations but at least one station must be presentThe data present in a station is described later in this book Common project dataincludes for example centrally managed message texts or texts for multilingualprojects

A project library can be created for each project Objects which are used in severalprojects are combined in global libraries Also relevant to a project is the program-ming device design with interface modules (eg LAN adapters) and memory cardreaders


37

131 Structured representation of project data

The project tree in the Project view displays the project data and the programmingdevice design in a tree structure (Fig 117)

The structure also includes the editors (tools) required for generating and editingthe data The project tree does not include the project library This is represented ina task card together with the global libraries in the task window under ldquoLibrariesrdquo

You can replace the names shown in angle brackets by names more appropriate toyour automation task

132 Project data and editors for a PLC station

If you add a PLC station (an S7-400 controller) to the project STEP 7 creates the cor-responding structure in the project data (Fig 118) A station is always required forediting in a project so that STEP 7 can create the data structures required for pro-gramming or configuration If you wish to write a user program without previouslyselecting a specific CPU you can select an ldquounspecified CPU 400rdquo from the hardwarecatalog and replace it later with a ldquorealrdquo CPU 400 if necessary
