Block Libraries Depending on whether V4 (old project, old CPU) or V5 (new project, new CPU) is used, use the File Manager in the SIMATIC Manager to hide the libraries you are not using. It can be advantageous to create a separate library for each project in the same project directory. In the first instance, keep the blocks there that will then be used in the project. If you upgrade the software at a later date, you can first try to import to a copy of this library before using the blocks in projects.C t P j t U th SIMATIC M t t th j tCreate Project Use the SIMATIC Manager to create the new project. The Manager handles all of the data generated during configuration.Resources The resources include the stations in the project (with their hardware), the S7 programs (with blocks in the user programs, chart containers containing blocks imported via CFC), networks, as well as the OS.Hardware Within the project, the AS hardware components (CPU, CP, and I/O

d l ) t b fi d i d ith th h d t t Thimodules) must be configured in accordance with the hardware structure. This configuration is loaded into the station and sets parameters for the modules.Plant Hierarchy A hierarchy (with a maximum of five levels) is used to display the system to be configured in the project. The hierarchy corresponds to the AKZ system (comparable to a directory tree). Assign Resources One AS and one OS can be assigned to each hierarchy l l Th b di t l l i h it th i t CFC d SFC h t OS

ITC 17/1

level. The subordinate levels can inherit the assignment. CFC and SFC charts, OS displays, reports and documents belonging to the assigned AS/OS are inserted in the last level (as “leaves“ on the “branch“).Software AS-specific or OS-specific tools are used to configure the software as needed. From the AS, you double-click the object in the plant hierarchy to start the software.

Info Flow Sensors, transducers, and DP process signal converters record process information. The AS processes this information and uses the same path to pass it on to the actuator. In parallel, commands are sent from the OS to the AS. AS information is displayed graphically on the OS.ET 200M The IM 153-1 interface module converts the process signal converter (I/O module) information into message frames for and from the AS.DP bus The bus (PROFIBUS DP) transports the message frames between the AS (DP master interface) and the ET 200M interfaces.AS (S7 417-4) The DP master interface reads in the telegrams in the AS. The driver blocks convert and process the message frames into process values. That is, open-loop control algorithms and closed-loop control algorithms convert the frames into commands and send the commands back to the distributed I/Os the same way. At the same time, the values are monitored. When specified

t t t th OSevents occur, messages are sent to the OS.System Bus The system bus can be MPI (Multi-Point-Interface), PROFIBUS or the industrial Ethernet. The system bus serves to communicate between the AS-OS, AS-AS, as well as the ES with the above mentioned nodes used for configuring and startup purposes. OS (WinCC) Data coming from the AS - embedded in process mimics - is displayed

hi ll d l ith ti b d d ith

ITC 18/1

graphically as measured values with a time-based sequence, and as messages with classification. The plant operator's commands are passed on the relevant AS and the response information displayed.

The configuration and startup steps shown on the following pages are based on this procedure.

ES Software The system should be configured with a uniform, plant-oriented approach. This is why the components shown in the slide above were expanded and coordinated with each other. The optional package expands the SIMATIC Manager and makes it possible to carry out the described task.System Orientation The optional process control components provide the PCS project planning engineer with an environment in which process automation tasks, operating and monitoring tasks, communication between the components,

d d t ti b i d t i t i t d Si thand documentation can be carried out in a system-oriented manner. Since the various SIMATIC components are managed in a system-related measuring point-oriented hierarchy (project planning engineer assigns AS objects, OS objects and documents to a specific system component), configuration, startup and maintenance become significantly more efficient.Import/export Interfaces to other configuration tools are provided. This is how PCS engineering fits into the whole process engineering/production engineeringengineering fits into the whole process engineering/production engineering approach. Division of Work

Work is divided when a project is handled on various networked PCS. Project work can be divided into several secondary projects on non-

networked PCs. The divided work is then combined into one project.

The plant hierarchy that normally abbreviates to PH, mirrors the hierarchical structure of your plant: Plant, unit, function etc. The PH allows you to make a lot of different settings and the most important of these are described below.• Number of hierarchy levels: Your plant structure influences the number of hierarchy levels. As a rule of thumb, the more complex the plant structure the higher the number of hierarchy levels you require to reflect your plant structure. Hierarchy folders with the default names are created when you work with the wizard.• Selecting the hierarchy level(s) that contribute to the name of the plant designation (also known as higher level designation): The higher level designation abbreviated to HID is used at many points in the PCS 7 project, for example, messages occurring during the process mode and tags contain this HID. This enables you to quickly determine the association of a message or tag to a specific plant unit. s a rule of thumb, the more hierarchy levels used to specify the HID and the longer each individual part is the longer and less easily recognizable the entire HIDeach individual part is, the longer and less easily recognizable the entire HID becomes.• Deriving the picture tree from the PH: The process pictures are arranged in a certain hierarchy: This allows you tochange from an overview picture to a lower level picture showing only part of the overview picture but with far greater detail. You can derive the tree of the process pictures from the plant hierarchy so that they conform to the plant hierarchy

What is CFC?CFC (Continuous Function Chart) is a graphic editor that can be used in conjunction with the STEP 7 software package. It is used to create the entire software structure of the CPU from ready-made blocks (or user defined blocks). When working with the editor, you place blocks on function charts, assign parameters to them, andinterconnect them. Interconnecting means, for example, that values are transferred from one output toone or more inputs during communication between the blocks.

Creating/Editing Import Files with the IEA File EditorIEA File EditorThe Import/Export Assistant (IEA) works with import/export files with a fixed format. A plant planning tool such as SIGRAPH EMR supports this format. To be able to create or edit import files even if you do not have a plant planning tool available, an IEA data editor is installed with Import/Export Assistant, that keeps exactly to the rules governing the structure of the import file.The IEA Editor "s7jieaEx.exe" is a separate application, in other words it can also be used outside the PCS 7 installation. It can be copied and made available to plant planners.

Situations for using the Editor (based on the example of a "process tag" / "model")model )The IEA File Editor is intended for the following situations:You have created a process tag type/model and created the import file with the IEA. With this import file, you want to create replicas of the model or process tags. The number of rows in the import file must be increased according to the number of replicas/process tags you want to create (for example by copying and editing).Y h t d t t / d l d t d th i t fil ith th IEA

You have created a process tag type/model and created the import file with the IEA. You want to change this model, for example by including further I/Os and need to extend the import file by adding these columns.You do not have a tool for creating an import file and want to use the IEA File Editor as a planning tool to structure the columns, column groups and rows of the import file and the corresponding values.Y t t i t fil ith t fil ( i ) B i

IntroductionUsing the wizard for process tag types, the process tag type is copied from the master data library to the specified target projects as a process tag and the corresponding data is then imported. This is based on an import file.Depending on the entries in the import file, you can create any number of process tags in one import action. As a result of the import, a process tag of this process tag type is created in the target project for every row of the import file according to the specified hierarchy path in the plant hierarchy.Sources for Process Tag TypesYou can store the following in the master data library:Standardized process tag types from the control system library PCS 7 Library, for example for motors, valves, PID controllers etc.User created process tag t pes from CFC chartsUser-created process tag types from CFC charts

Process Tag TypesProcess tag types are a very good function when you use numerous process tagsof the same type in a project. A CFC chart forms the basis of a process tag type.When you use process tag types you do not have to create a CFC chart for each

ITC 79/1

When you use process tag types, you do not have to create a CFC chart for eachindividual process tag. You can create a type of base CFC chart with all of thegenerally used parameters and then duplicate this chart using the import/exportfunctions. In a way, you are creating an instance of a process tag type. With theimport/export function, you enter the required custom parameters for each processtag to be generated

RequirementA CFC chart has been created in the project or in the master data library that contains the automation functions, parameters, and messages of the process tag to be implemented according to a specified process tag description.

Procedure1 Select the intended CFC chart in the SIMATIC Manager (any view)1- Select the intended CFC chart in the SIMATIC Manager (any view).2- Select the menu command Options > Process Tags > Create/Modify Process Tag Type...

Result: The wizard is started and the "Introduction" page is displayed. The current master data library is displayed.3- Click the "Next" button.

Res lt The dialog for cop ing the chart to the master data librar as aResult: The dialog for copying the chart to the master data library as a process tag type opens.4- Confirm the dialog box with OK.

Result: The wizard changes to the "Which I/Os do you want to assign to the process tag type?"

5- In the left-hand window "I/Os in the chart of the process tag type", select the flagged I/O for "Parameter" and "Signal". (By double-clicking or selecting and clicking the "Arrow" button).

Result: The flagged I/O is adopted and displayed bold.6- In the right-hand window "I/O points for parameters/signals", you can edit the selected flagged I/Os.

The "Parameter/Signal" columns can be edited (using a drop-down list b )box),

"Process tag interface" and "Category" (using a drop-down list box). The drop-down list box appears when you click the input field.

7- In the left-hand window, "I/Os in the chart of the process tag type", select the messages of the relevant blocks. All the messages are displayed in the "I/O points for messages" window.8 Ch k th l ti d li k th "N t" b tt d th "Fi i h"8- Check the selection and click on the "Next" button and then "Finish".

Result: The new process tag type is stored in the master data library. The CFC chart that was the origin of the process tag type is located in the S7 program and can continue to be used there or, if it is no longer required, can be deleted.

Result: The import dialog opensResult: The import dialog opens. After starting the function, the wizard searches for the process tag

types and corresponding import files (in all hierarchy subfolders as well) and displays them. The import function will include all listed import files.3- If you do not want to import certain files, you can select them and remove them from the list with the "Remove" button. With the "Other File" button, you can browse for a different import file and select it instead of the selectedcan browse for a different import file and select it instead of the selected file. 4- Start the actual import with the "Next" button followed by "Finish".

What is SFC?

SFC (Sequential Function Chart) is a sequential control system partitioned toensure step-by-step execution with control passing from one state to the next statedependent on conditions. With a sequential control system, basic automationfunctions, for example CFC charts are controlled based on state changes and canbe selectively processed. You create SFC charts in the SFC Editor.

ITC 93/1

What are Sequence Path Elements?An SFC chart consists of 1 to 8 and an SFC type of 1 to 32 sequencers each with asequence of sequence path elements. These elements include the following:. Step. TransitionAnd below a sequence (can be freely positioned):. TextThe remaining elements are structures made up of different elements:. Sequence. Simultaneous sequence. Alternative sequence. Loop. Jump

ITC 94/1

Operating State Logic for SFC (SFC-OSL)The current operating state of the SFC-OSL can be changed by the following events:. Commands (Start, Resume, Hold, ...) in the "MANUAL" or "AUTO" modes.. External signals (inputs of the SFC, commands from another SFC, ...).. Internal signals (commands from own sequencers, from the test mode or SFC Visualization)Visualization).. Implicit state change.
