Element name

Example: Velocity

Datasource

Location where the trace data is buffered.

:

• <local application>: The trace record is listed below the local application. The visual­ization that contains the trace is located below this application.

  When the application is downloaded, the trace configuration is downloaded to the local device. During execution, the data is stored locally in the trace buffer.

• <data source name>: Data source that identifies the remote device where the trace record is created.

  When the local application is downloaded with the visualization, the trace configuration is downloaded to the remote device. During execution, the trace buffer is filled, and the trace data is transferred and then displayed in the local visualization as HMI.

  Example: DataSoure_PLC_A

  Note: The trace buffer is filled only if the remote application is being executed. The data recording is started when the local visu­alization is started.

Application

Application where data was recorded.

: Lists all applications that are present below the data source.

Requirement: A remote data source (not <local application>) is referenced in the Datasource property.

Type of element

Trace

Trace

 <name of trace configuration>: Opens the Trace Configuration dialog where you can modify the trace configuration.

X

The x-coordinate of the upper left corner of the element

Specified in pixels

Example: 10

Y

The y-coordinate of the upper left corner of the element

Specified in pixels

Example: 10

Width

Specified in pixels

Example: 150

Height

Specified in pixels

Example: 30

Tip: You can change the values in X, Y, Width, and Height by dragging the corresponding symbols  to another position in the editor.

Angle

Static angle of rotation (in degrees)

Example: 35

The element is displayed rotated in the editor. The point of rotation is the center of the element. A positive value rotates clockwise.

Tip: You can change the value in the editor by focusing the element to the handle. When the cursor is displayed as a rotating arrow , you can rotate the element about its center as a handle.

(1): Handle

Note: If a dynamic angle of rotation is also configured in the property Absolute movement ‣ Internal rotation , then the static and dynamic angles of rotation are added in runtime mode. The static angle of rotation acts as an offset.

Show cursor

: A cursor (vertical line) is displayed at the mouse position. The trigger and variable values where the cursor points are displayed as a tooltip.

Overwrite existing trace on PLC

: If a trace with the same name is on the PLC, then it is overwritten at download with the configuration that is defined here.

Number format

Number format of values in the tooltip in printf syntax (example: %d, %5.2f).

Reset Trigger

Variable (BOOL).

Standard control variable: bResetTrigger

TRUE: Resets the triggering. After the action is executed, the variable is set automatically to FALSE.

Start Trace

Variable (BOOL).

Standard control variable: bStart

TRUE: Starts the trace. After the action is executed, the variable is set automatically to FALSE.

Stop Trace

Variable (BOOL).

Standard control variable: bStop

TRUE: Stops the trace. After the action is executed, the variable is set automatically to FALSE.

Save trace to a file

Save Trace

Variable (BOOL).

Standard control variable: bStore

TRUE: Saves the current trace configuration and the data that is stored in the development system to a file. When the action is ended, the variable is set automatically to FALSE.

File name

Variable (STRING) that contains the file name of the file to be saved.

Standard control variable: sStoreFilename

Load trace from file

Load Trace

Variable (BOOL).

Standard control variable: bRestore

TRUE: Reads the file specified below and loads its contents into the trace editor. The file contains a trace configuration and possibly also trace data. To do this, the stored trace configuration must match the application where the trace configuration is located. When the action is ended, the variable is set automatically to FALSE.

Note: A trace configuration can be loaded from a file only under special circumstances. The file must have been created with exactly the same (running) application with which it will then be loaded. The consequence of changing the running application (for example by downloading again) is that a file which was previously created from the application cannot no longer be read into the application. Even external manual changes to the file can cause this. You should edit only those configuration settings that have an effect on displaying the variables. If you change variable definitions directly in the file (for example by replacing variable x with v y), then the file cannot be loaded.

File name

Variable (STRING) that contains the file name of the file to be read.

Standard variable: sRestoreFilename

X

X-coordinate of the point of rotation

Y

Y-coordinate of the point of rotation

Movement

X

Variable (numeric data type). Defines the X position (in pixels).

Example: PLC_PRG.iPos_X.

Increasing this value in runtime mode moves the element to the right.

Y

Variable (numeric data type). Defines the Y position (in pixels).

Example: PLC_PRG.iPos_Y.

Increasing this value in runtime mode moves the element downwards.

Rotation

Variable (numeric data type). Defines the angle of rotation (in degrees).

Example: PLC_PRG.iAngle1.

The midpoint of the element rotates at the Center point. This rotation point is shown as the symbol.

In runtime mode, the alignment of the element remains the same with respect to the coordinate system of the visualization. Increasing the value rotates the element to the right.

Interior rotation

Variable (numeric data type). Defines the angle of rotation (in degrees).

Example: PLC_PRG.iAngle2.

In runtime mode, the element rotates about the point of rotation specified in Center according to the value of the variable. In addition, the alignment of the element rotates according to the coordinate system of the visualization. Increasing the value in the code rotates clockwise.

The rotation point is shown as the  symbol.

Note: If a static angle of rotation is specified in the Position ‣ Angle property, then the static angle of rotation is added to the variable angle of rotation (offset) when the visualization is executed.

Invisible

Variable (BOOL). Toggles the visibility of the element.

TRUE: The element is not visible at runtime.

Animation time

Time that the element executes an animation (in milliseconds)

Example: 500

Move to the foreground

Property value (BOOL)

TRUE: At runtime, the element is displayed in the foreground.

FALSE: At runtime, the element is displayed in the layer where it was inserted in the visualization editor.

Access rights

Opens the Access rights dialog. There you can edit the access privileges for the element.

Status messages:

• Not set. Full rights.: Access rights for all user groups : operable

• Rights are set: Limited rights: Access is restricted for at least one group.
