3 Basics Introduction

Faceplates are objects that are made up of existing picture objects. Faceplates offer the following advantages: • Changes from a central location • Reuse in other projects • Reducing the workload for the configuration You create and change faceplates in the "Faceplates" editor. The generated blocks are adopted in the "Project Library" and can be added into pictures like other objects.

Using a faceplate After you have generated a faceplate, the faceplate appears as an object in the project library. You add the faceplate to your process pictures and configure it for the respective usage location in the properties window.

Faceplate instance Inserting a faceplate into a process screen generates an instance of this faceplate. When editing the faceplate in the project library, the created faceplate instance is automatically updated once released.

Reusing faceplates in several projects WinCC Advanced offers the option of adopting faceplates in a global library. This enables you to reuse the faceplates in other projects. As soon as you add a faceplate from a global library into a picture, the faceplate is also filed in the project library. You change the faceplate only in the project library; the changes are not automatically adopted in the global library.

4 Functional Mechanism of this Faceplate 4.1 Interfaces of the faceplate window Figure 4-1

The interface of a faceplate generally differentiates between dynamic and static properties: • Via the interface a dynamic property is always connected with a tag which

supplies the property in runtime with values. • Static properties can be directly configured in the picture editor. The properties

are then saved together with the faceplate or on the interface of the faceplate. Static properties cannot be changed in Runtime.

4.2 Dynamic properties of the faceplate window

4.2.1 Animation

The tags of this group are used to display and represent the faceplate windows; process connection is optional.

Visibility The “Visibility” property is used for influencing the display properties of the faceplate window during runtime. The following properties are influenced: • Open • Close • Minimize • Maximize • Selecting the individual tabs Table 4-1

Tag used

Symbolic name Analogue_DB.OP_VISIBILITY Data type Byte Access method Symbolic access Length 1 byte Acquisition cycle 100 ms Acquisition mode Cyclic during operation

Bits 0..6 serve for opening or selecting the individual tabs of the faceplate window (maximized display). If more than one bit is set, only the background of the faceplate window is displayed. If bit 7 has been set, only the title bar of the faceplate window is displayed (minimized display), irrespective of the status of the remaining bits. If none of the bits are set, the faceplate window is closed. The following table shows the setup of the tags.

Table 4-2

Bit 7 6 5 4 3 2 1 0

Selec-tion

Minimize Tab 5 (Service)

Tab 4 (limits)

Tab 3 (trends)

Tab 2 (messages)

Tab 1 (overview)

Note The tag can also be defined as an internal tag without PLC connection if only a limited number of control tags are available.

If the tag has a PLC connection, read and write access is possible from the controller. Aside from the known screen selection, the respective faceplate window can also be opened from the controller and a specific tab can be selected.

4.2.2 Process

The tags of this group feature a process connection and are the basic interface between controller and operating device.

Command The “Command” property is used to transmit commands from WinCC Advanced to the controller. The PLC block analyses the control command, executes the desired action and then initiates a reset of the pending control command. For this purpose, the value of the control parameter is set to “0”.

4.2.3 Process_Limits

The tags of this group contain a process connection and can be operated and monitored in the “Overview” or “Limits” tab. The “Trends” tab clearly shows the relevant values as curves and lines; however, the tags can only be monitored in this tab. The tags are used to define the high and low limit of an analog value and to define limits for message triggering.

HighLimit The “HighLimit” property indicates the high limit (limit) of the analog value. Table 4-8

Tag used

Symbolic name Analogue_DB.OP_HI_LIM Data type Real Access method Symbolic access Length 4 byte Acquisition cycle 100 ms Acquisition mode Cyclic during operation

4.3 Static properties of the faceplate window Static properties cannot be changed during runtime. Therefore they generally have no process interface.

4.3.1 Process_Trends_Value

The properties of this group define the individual trends of the faceplate window.

Trends The “Trends” property is a “SimpleCoreCollectionWrapper” and defines the trends of the “Trends” tab. To edit the trends, select the “Trends” property, the trends editor is opened using the displayed “…” button. Figure 4-3

Figure 4-4

4.3.2 Label

The properties of this group are used to label the faceplate window.

Text The “Text” property is a text string and is displayed in the left half of the title bar. Here, for example, the higher level definition (HLD) or the location of usage can be shown. You can change this text at the interface of the faceplate under the “Label” property. Figure 4-5

Unit The “Unit” property is a text string and used in the “Overview” and “Limits” tabs to display the physical unit of the analog value.

4.3.3 UserManagement

The properties of this group serve for assigning the user rights. In the project tree under the “User administration” item, you can configure these rights individually.

Service The “Service” property is an “HmiObjectHandle” and is used as access protection for the “Service” tab.

NOTICE In this application the “Service” group and the “admin” user is used as authorization. The password is preset to “100” and can be changed in the user administration of WinCC Advanced.

If you create a new instance of the faceplate window and do not interconnect the “Service” property, the “Service” tab has no access protection.

Visibility The “Visibility” property is used for influencing the display properties of the faceplate window during runtime. The following properties are influenced: • Open • Close • Minimize • Maximize • Selecting the individual tabs

Note When clicking the faceplate icon, the “OP_VISIBILITY” tag is always loaded with value “1”. This results in the respective faceplate window being displayed with tab 1.

Bits 0..6 serve for opening or selecting the individual tabs of the faceplate window (maximized display). If more than one bit is set, only the background of the faceplate window is displayed. If bit 7 has been set, only the title bar of the faceplate window is displayed (minimized display), irrespective of the status of the remaining bits. If none of the bits are set, the faceplate window is closed.

Note The tag can also be defined as an internal tag without PLC connection if only a limited number of control tags are available.

If the tag has a PLC connection, read and write access is possible from the controller. Aside from the known screen selection, the respective faceplate window can also be opened from the controller and a specific tab can be selected.

4.6 Control and status signals

4.6.1 Processing of switching commands in the controller

The WinCC Advanced control tag “OP_dwCmd” of a block is used to transmit commands from WinCC Advanced to the PLC. The PLC block analyses the control command, executes the desired action and then initiates a reset of the pending control command. For this purpose, the value of the control parameter is set to “0”. Further notes for the use in WinCC Advanced can be found under the “Command” property. Figure 4-7

4.6.6 Enabling/disabling simulation

The “Simulation ON” mode can simulate the analog signal. This function is important, for example, if automatic functions are already to be tested during the configuration phase, but a process interface does not yet exist. Without simulating the feedbacks, many automatic functions (e.g., step sequences) cannot be successfully executed since the feedbacks are frequently requested in step enabling conditions or cause errors.

5 Configuration and Settings Here you will find out …

how the faceplate of this application is structured. This chapter is necessary if you wish to design the faceplate according to your needs.

Principle of layer technique The principle of layer technology was used for the faceplate of this application. The layer technology enables differentiated editing of the faceplate objects. The faceplate editor and the picture editor have 32 layers; however, the layers of the faceplate are only available within the faceplate editor. After adding a faceplate from the library into the picture editor (creating a faceplate instance) it can only be assigned a layer within the picture editor, just as any other picture object. However, the offset in depth within the faceplate remains.

Offset in depth structure Objects of “layer 0” are in the background of the pictures, objects of “layer 31” are in the front. The objects of a single layer are also arranged hierarchically. When creating a picture or a faceplate the first added object is placed at the back within the layer. Each further object is added one position further to the front. Within a layer you can also move the objects to the front and to the back.

Editing faceplates Changes at the faceplates can be performed at a central location. There are two options to change a faceplate and its instances: • Changing the faceplate via an instance (location of usage)

Select the faceplate in the workspace of the picture editor and select the “Edit faceplate” command via the context menu.

• Changing the faceplate in the library Open the project library and select the faceplate. Select the “Edit faceplate type” command via the context menu of the faceplate.

• After subsequent release of the faceplate, the changes made are updated in the instances and also in the project library.

Working with layers One of the 32 layers is always active. When inserting objects into a picture or a faceplate they are assigned to the active layer by default. The enabled layer is selected with a pen icon in the "Layout > layer” task card. Figure 5-1

When opening a picture or a faceplate all 32 layers are always displayed. In the "Layout > Layers” task card you can hide all layers apart from the enabled layer. You then specifically edit the objects of the active layer.

5.1 Configuring the faceplate window The faceplate window is divided into several layers. Since neither the layers of a faceplate nor the layers of a picture can be accessed during runtime, the application uses the “Visibility” animation type of each object. For this purpose, the “Visibility“ property is connected in the faceplates.

5.2 Layer 0 – frames “Layer 0” contains all important objects required for displaying the faceplate window. These objects represent the faceplate window frame. Figure 5-2

The following different display types exist: • Open • Close • Minimize • Maximize

6 Startup of the Application Here you will find out …

how to integrate the “ANALOGUE” STEP 7 block (FB 640) and the respective WinCC Advanced faceplate into an empty or existing project. This example uses the STEP 7 block that is not interconnected, the “AnalogueIcon” faceplate icon and the “Analogue” faceplate window.

Note The application provides an executable project. You only need to perform the steps explained in this chapter if you wish to integrate the blocks into your own project.

If you only want to visualize the functionality of this application it suffices to unzip the “Faceplates_WinCC_Advanced_Blocks_Code.zip” file and to open it in the TIA Portal.

Transfer the blocks to a S7 controller of your choice and start the HMI station (WinCC Advanced RT) integrated in the project on a connected PC.

NOTICE The process connection was configured for Industrial Ethernet. Adjust the settings for CPU, “HMI station” and “PG/PC interface” on demand.

6.1 Configuring the STEP 7 block Table 6-1

Step Description

1. Creating a new project • Create a new project with an S7 controller and an HMI station (WinCC

Advanced), or open an existing project. • If you are using an existing project, it is advisable to create a backup

before performing the following steps. 2. Inserting blocks

• Open the project of this application with the TIA Portal. • Copy the FB640 block to the respective directory of the S7 program. • If you are using a new project, also insert the calling block OB1 and the

DB620 instance data block into your project. 3. Calling the blocks

• When using an existing project you must integrate the FB640 block into the cycle of the PLC. The necessary instance data block is then automatically generated.

8. Integrating the messages and tags • Within the library, select the “Master copies > ANALOGUE” category. • Using drag & drop, move the “AnalogueTags” to the “HMI tags” folder and the

“AnalogueAlarms” messages to the “HMI messages” folder. Notice: The message numbers of this application occupy the number range starting at 10001. Check your existing project before integrating the messages and enable this area if necessary. Furthermore, check the symbolic connection of the tags and restore it, if necessary.

9. Interconnecting the faceplates

• Interconnect the dynamic properties of the faceplate window. More information on this matter can be found in Dynamic properties of the faceplate window.

• Interconnect the static properties of the faceplate window. More information on this matter can be found in Static properties of the faceplate window.

• Interconnect the dynamic properties of the faceplate icon. Further information is available in Interfaces of the faceplate symbol.

Service Figure 7-6

NOTICE The “Service” tab is protected and requires the authorization of the “Service” group for the selection.

The default user is “admin” and the default password “100”.

If you create a new instance of the faceplate window and do not interconnect the “Service” property, the “Service” tab has no access protection.

In this view you can perform the following actions: • Toggle S7 Periphery / Real Value.

– An analog value is scaled depending on the limits in the “Overview” tab. – The scaling of an analog value can be both unipolar and bipolar.

• Hysteresis changeover: Percental/Absolute • switchover between simulation / real process mode.

Note The hysteresis only influences the deactivation of the limit messages.

It does not influence the scaling of the analog value or the triggering of a limit warning.
