2. OPERATOR CONTROL WITH WINCC FLEXIBLE

2.1 System Description

Since processes are becoming more and more multi-layered and the demands on the functionality of

machines and plants are increasing, the operator needs a high-performance tool for controlling and

monitoring production plants. An HMI system (Human Machine Interface) represents the interface

between a human being (the operator) and the process (machine/plant). The controller actually

controls the process. That is, there are two interfaces: one between the operator and WinCC flexible

(at the operator panel), and another interface between WinCC flexible and the controller.

The WinCC flexible Engineering System is the software that is used to handle all required

configuring tasks. The WinCC flexible Edition determines which operator panels of the SIMATIC

HMI spectrum can be configured.

WinCC flexible Runtime is the software for process visualization. In runtime, the project is executed

in the process mode.

WinCC flexible performs the following tasks:

• Displaying the process

The process is mapped to the operator panel. If a status changes in the process, for example, the

display at the operator panel is updated.

• Operating the process

The operator can operate the process by means of the graphic operator interface. For example, the

operator can specify a setpoint for the controller, or start a motor.

• Reading out messages

If critical process states occur in the process, a message is triggered automatically; for example, if

the specified limit is exceeded.

• Archiving process values and messages

The HMI system can archive messages and process values. In this way, you can document the

process characteristics, and you can also access older production data later.

• Documenting process values and messages

The HMI system can read out messages and process values as protocol. Thus, you can have

production data read out after the end of a shift, for example.

• Managing process parameters and machine parameters

The HMI system can store parameters for processes and machines in recipes. With one operational

step, you can transfer these parameters from the operator panel to the controller, in order to change

production to another product variant.

2.2.2 Installing WinCC flexible

After all system requirements that have been mentioned are met, install WinCC flexible from the CD-

ROM. Select the scope for installing components and product languages.

• Standard installation: recommended

• Minimum installation: to save memory

• User defined installation: to specify yourself which components and product languages are

installed

In addition, the required licenses have to be transferred. You can install the licenses along with the

components and product languages, or you can install them subsequently. If you have obtained

WinCC flexible options, install each option separately. An option is installed by loading the

associated license key.

Detailed information regarding the installation are provided in the Installation Instructions on the CD-

ROM 'WinCC flexible Software CD1’ in the folder "Documents\<Language>\Installation Guides“.

2.2.3 Deinstalling WinCC flexible

Close all applications that are open, particularly the WinCC flexible Engineering System and WinCC

flexible Runtime. Deactivate WinCC flexible Smart Start.

Additional notes on WinCC flexible Smart Start are provided in the chapter "WinCC flexible Smart

Start".

Open the system control by means of "Start ► Settings ► System Control".

In the system control, double click on the entry "Software". The dialog "Software" is opened.

In the dialog "Software", select the entry "SIMATIC WinCC flexible 2005". The button

"Change/remove" is displayed.

Click on the button "Change/Remove". The WinCC flexible InstallShield Wizard is opened.

Activate the option "Remove program" and click on the button "Continue".

Confirm the deinstallation with "OK". WinCC flexible is removed from the configuring computer.

2.2.4 Totally Integrated Automation

In addition to an HMI system such as WinCC flexible, a complete automation solution includes other

components, such as controller, process bus and periphery. WinCC flexible offers a particularly

extensive integration with components from the SIMATIC product family:

• Integrated configuring and programming

• Integrated data management

• Integrated communication

Integration in SIMATIC STEP 7

Process variables are the connecting link for communication between controller and the HMI system.

Without the advantages of Totally Integrated Automation, you have to define each variable twice:

once for the controller, and once for the HMI system.

Integrating SIMATIC STEP7 into the configuration interface lowers error frequency and configuring

effort. While you are configuring, you are directly accessing the STEP7 symbol table and the

communication settings:

- The STEP7 symbol table includes the data point definitions (for example, addresses or data

types) that were specified when you generated the control program.

- The communication settings contain the bus addresses and the control protocols

- Communication is set with NetPro, for example.

3. PROJECT DESCRIPTION

3.1 Hardware Configuration

In our sample program for a color mixing plant, we are using a programming device with the WinCC

flexible 2005 Advanced Engineering System and WinCC flexible 2005 Runtime.

The color mixing plant is controlled by means of a SIMATIC S7-300. By using a touch panel

(TP177B), the operator can operate the process using the graphic operator interface. For example,

the operator can specify a setpoint for the controller, or start a motor.

The programming device, the SIMATIC S7-300 controller and the operator panel TP177B are

connected to each other by means of the MPI.

The color mixing plant is connected to the controller with digital inputs and outputs.

TP177B as operator panel

Note

With WinCC flexible 2005 Runtime, the touch panel TP177B can also be represented on the

programmer. However, when starting WinCC flexible Runtime, the MPI address of the panel

(MPI=1) is set automatically on the programmer. When using a real panel, the MPI address has to

first be reset on the programmer to MPI=0.

3.2 Plant Description

A color mixing plant is controlled with a SIMATIC S7-300 in the automatic or in the manual mode. In

the "Automatic“ mode, the three tanks are filled with a two step control. At the minimum level, the

inflow valve opens automatically, and after the maximum level is reached, it is closed again. After the

start button is operated, the specified program is executed: first, the outflow valves are opened and

the container is filled from tanks with the specified amounts. After the outflow valves are closed, the

mixer motor is started. After the mixing time has expired and after a short idle phase, the outflow

valve of the container is opened and the finished color mixture is drained. When the container is

empty, the lamp of the start button lights up, and a new color mixture can be started.

In the "Manual“ mode, the automatic outflow is canceled, and all valves as well as the mixer motor

can be operated manually. The lamps in the buttons for manual operation are lit.

Note

The specified amounts and the time base are determined by the program. If you want another color

mixture, the specified amounts and the time base have to be changed, and a new program has to be

loaded to the controller.

3.3 Task Definition

At the color mixing plant, the program was changed with the programmer each time the mixing ratio

changed. Since such changes are not only time consuming, but also dangerous if wrong entries are

made, it was decided to expand the color mixing plant with a TouchPanel TP177B.

By using the panel, the following requirements are to be met:

- The color mixing plant can also be operated with the panel.

- The levels of the tanks and the container are to be displayed as a bar and also as a numerical

value.

- The motion of the mixing motor is to be shown graphically.

- The specified amounts are to be entered on the panel.

- The minimum and maximum levels of the three tanks are to be entered in separate tank

graphics.

- The operating modes can be switched using the panel; the respective operating mode is

displayed on the panel.

- The completed mixtures are to be stored on the panel as recipes; the operator only has to select

them.

- The levels are monitored. If danger arises, messages are to be read out.

- The color mixing plant can only be operated after a password was entered.

- Panel TP177B is to communicate with the SIMATIC S7-300 controller by means of the MPI.

3.4 Configuration

On the programmer, process visualization is generated for the color mixing plant, using the

configuring software WinCC flexible 2005 Advanced. The process values are represented by

graphics and graphic objects. Default values can be transferred to the controller with operating

elements. The operator panel and the machine or the process communicate by means of variables

via the controller. The value of a variable is written to a memory area (address) in the controller.

There, it is read by the operator panel.

Process visualization is stored and after generation, it is transferred by the programming device to

the operator panel TP177B.

After the panel is powered up, the process can be monitored and the plant can be operated.

6.1.1 Menus and Symbol Bars

The menus and the symbol bars contain all the functions you need to configure your operator panel.

If a corresponding editor is active, menu commands or symbol bars are visible specific to the editor.

If you point to a command with the mouse pointer, you will get a corresponding QuickInfo for each

function.

When a new project is set up, the symbol bars are positioned at the upper screen boundary as a

matter of standard. The position of the symbol bars is coupled to the user that is signed on in

Windows. If you have moved symbol bars with the mouse, the positions that the symbol bars had at

the last close are restored after starting WinCC flexible.

The following menus are available in WinCC flexible:

The availability of the menus and their instruction set depends on the editor that is used.

6.1.2 Work Space

In the work space, the objects of the project are edited. All elements of WinCC flexible are arranged

around the work space. Except for the work space, you can arrange and configure all elements

according to your own requirements; for example, shifting or hiding.

In the work space, project data is edited either in table form (for example, variables) or graphically

(for example, a process image). Each opened editor is represented in the work space on its own tab

sheet. For graphic editors, each element is represented by a separate tab sheet. If you have several

editors opened at the same time, only one tab sheet is active. To switch to another editor, click on

the corresponding register sheet. You can have a maximum of 20 editors opened at the same time.

6.1.3 Project Window

The project window is the central control point for project processing. All constituent parts and all

available editors of a project are displayed as a tree structure in the project window and can be

opened from there. To each editor, a symbol is assigned. With it, you can identify the associated

objects. Only those elements are displayed in the project window that the selected operator panel

supports. In the project window, you can access the device settings of the operator panel, language

support, and version management.

The project window represents the structure of the project hierarchically

• Project

• Operator panels

• Folders

• Objects

In the project window, objects are set up and opened for processing. You can set up folders to

structure the objects of your project. The project window is operated similar to the Windows

Explorer. For all objects, you can call a context menu where the most important commands are

combined.

Elements of graphic editors are shown in the project window and in the object window. Elements of

tabular editors are displayed only in the object window.

The property window is available only in certain editors.

In the property window, the properties of the selected object, arranged by categories, are displayed.

As soon as you exit an input field, the values that were changed are effective.

If you enter an invalid value, it is displayed with a background color.

Using QuickInfo, information is provided about the valid value range, for example.

IMPORTANT NOTE

The inputs in the property window are not accepted by operating the input key, but by exiting the

field, or by clicking on another field. Please note where you are clicking after making inputs via the

keyboard. Otherwise, you will possibly be changing to the properties of the selected object, or a

6.2 Configuring Displays

A display can consist of static and dynamic parts. The controller does not update static parts, such

as texts and graphics.

Dynamic parts are connected to the controller, and visualize current values from the controller’s

memory. Visualization can be in the form of alpha-numerical displays, curves, and bars. Dynamic

parts also consist of inputs made at the OP that are written to the controller’s memory. They are

interfaced with the controller by means of Variables.

For our color mixing plant, five displays are to be generated initially.

Display Template

This display is set up automatically, and contains central functions.

In the upper area of the display, a permanent window is generated. Here, the levels of the tanks, of

the container and the project name are shown.

In the lower area of the display, the message window and the message indicator are shown. These

objects are also embedded in all displays, and are opened in the display’s foreground if there is a

message, for example.

Basic Display

This display also is set up automatically, and it is also defined as start picture. Here, the entire plant

is shown

Changing the operating mode, starting the mixing process, operating the mixer motor manually, and

opening the outflow valve can be performed by means of buttons. The motion of the mixer and the

states of the valves are shown graphically. By means of input fields, the amounts of the individual

additives are specified. In addition, it is to be possible to jump to the other displays. Using the button

END, the runtime at the panel is terminated, and a new transfer can be made.

Tank1

In the third picture, the valves of Tank1 can be operated manually. The maximum and minimum

amount of filling has to be preset at linear regulators. By means of buttons (Open valve), the inflow

and outflow valve can be opened or closed. The valves are shown graphically, and change color

when they are open.

The level is indicated in red. If the maximum level is reached, the inflow valve is closed in the

automatic mode. When the tank is completely full, the inflow valve can not be opened.

With additional buttons, you can switch to the other tanks, or to the basic display.

Tank2, Tank3

The displays for Tank2 and Tank3 are structured exactly like the display for Tank1.

The valves and the level of Tank2 are colored green.

The valves and the level of Tank3 are colored blue.

6.7 Configuring a Connection

So far, we worked in our project without accessing the SIMATIC S7 controller.

On our panel, levels are to be displayed and fill setpoints are to be entered.

For operator and display objects that access the process values of a controller, first the connection

to the controller has to be configured.

Here, you specify how and by means of what interface the panel communicates with the controller.

Double click on the window Connections.

All parameters are already set through the settings in the hardware configuration.

Note

To set up a new connection, double click in the free field in the first column. Change the connection

parameters of the newly created connection

7 DISPLAY AND OPERATOR OBJECTS

Display and operator objects are graphic elements with which process displays are designed.

In Runtime, all display and operator objects behave dynamically.

In addition, you can make the properties of objects dynamic.

One example of this is the graphic of a tank whose liquid level is displayed as varying, depending on

the corresponding process value.

Another example for the dynamic behavior of an object is a button that triggers a certain function. In

principle, you can make all graphic objects dynamic.

You can configure the following:

- The object changes its appearance: color and blinking.

- The object moves in the picture.

- The object is inserted/removed.

For operator elements, you can configure the following:

- The object is enabled or disabled for operation.

- By operating the object -for example, by clicking on it- an event is triggered to which the

processing of a function list is configured.

7.1 Levels

For differentiated representation of a picture and for editing the objects in it, levels and multi- layering

of the objects are provided.

A picture has 32 levels. You can insert objects in each level. The assignment to a level specifies

the depth of the layer of an object in the picture. Objects of Level 0 are located deep in the

background of the picture, objects of Level 31 in the very foreground.

In addition, objects in a single level are also staggered.

When creating a process image, the objects of an individual level are -by default- arranged in the

sequence in which they were configured. Within the level, the object that was inserted first is located

at the very back. Each additional object is inserted one position ahead of it. The position of the

objects in relation to each other can be changed within the level. There is always an active level.

When you insert objects in a figure, they are assigned to the active level by default. The number of

the active level is indicated in the symbol bar "Level".

In the level palette, the active level is highlighted in color.

When you open a picture, all its 32 levels are always displayed.

With the level palette, you can hide, after opening, all levels except for the active level. This allows

you to specifically edit the objects in the active level.

8.2 Configuring the Display and Operator Objects in the Pictures “Tank2“ and “Tank3“

The picture for Tank2 and Tank3 is structured exactly like the picture for Tank1.

In the picture “Tank2“, the level of the tank and the valve function are to be displayed in the color

green and the variables for Tank2 are used; for example, “INHALT_T2“ (Content Tank2).

In the picture “Tank3“, the level of the tank and the valve function are to be displayed in the color

blue and the variables for Tank3 are used; for example, “INHALT_T3“.

Configure the tank pictures by either repeating the steps described in 8.1 and using a different color

and variable assignment, or by copying the objects of the picture “Tank1“ and inserting them in the

picture “Tank2“ and “Tank3“.

You can highlight and copy several objects with SHIFT+mouse click.

Then switch to the picture “Tank2“ and “Tank3“ and insert the objects.

After you inserted the objects, only the color assignments and the variables have to be changed. For

the bars and the valves, the size and the position have to be adjusted to the background graphic in

addition.

9 CONFIGURING MESSAGES

The representation of the color mixing plant is by and large completed. What still needs to be done

are the messages. Messages are generated if an event bit occurs (bit messages), or when a limit is

overrange or underrange (analog messages).

The message texts contain a description of the cause for the message with the message status, or

only notes on the current operation of the plant.

We differentiate message classes such as warnings or errors for operational messages and fault

messages. Operational messages refer to the states of a machine or a process. Fault messages

indicate alarms of a machine or a process and have to be acknowledged.

9.1 Analog Messages

The levels of the three tanks and of the container are to be monitored.

If a tank or the container is full, a fault message is to be read out.

In the project window, double click on analog messages.

Enter the message texts and the monitored variables.

For the tank limits, use the variable of the maximum fill setpoint.

For the container limit, enter as the constant value 2999.

Note

You can also generate several messages for one monitored variable.

You only have to set different limits with the rising or falling edge.

9.2 Bit Messages

Bit messages are configured just like analog messages; only here, the message is read out when an

event bit is pending.

9.3 Message Window

The message texts are to be displayed in a message window.

The message window is configured into the template picture. This inserts it automatically in the

background of all other pictures.

With a double click, open the picture "Template“ in the project window.

From the tool window under Expanded Objects, drag the Message Window into the template

picture. Set the inserted message window. Use the message window for pending and

acknowledged messages. At Message Classes, select Error and System.

9.4 Message Indicator

The message indicator is displayed if messages of the specified message class are pending or have

to be acknowledged. The message indicator can have two states:

- Blinking: At least one unacknowledged message is pending.

- Static: The messages are acknowledged, but at least one of them is not cleared.

When clicking on the message indicator, the configured action is performed.

In the template picture, set the active level to 1; that puts the message indicator in the foreground.

Drag a message indicator into the template picture, and assign the function

“ZeigeMeldefenster“ (show message window) at Click and Click with blinking.

11 CONFIGURING USER MANAGEMENT

User groups and users can be set up by means of user management. The access rights are granted

to a user group. These access rights govern the access to data and functions to protect them from

unauthorized operation. A user is then assigned to a user group.

11.1 Setting up User Groups

In the project window, double click on Gruppen (groups) in the folder Benutzerverwaltung Runtime

(user management runtime). By default, two user groups are already set up: the group of

administrators with all authorizations, and the group of users with authorization to operate. However,

we can grant users additional authorizations.

For our color mixing plant, we need two more user groups with additional authorizations.
