2 Visual Components Manuals

A single letter can be capitalized or a special character can be entered using the 'Shift' key.
To do this, the 'Shift' key must be pressed before the desired letter key.
Warning:
Pressing several keys simultaneously on the touch keypad is not possible due to the
construction of the analog touch display! Therefore, characters must be entered one after
another. The 'Caps Lock' key can be used if several capitalized letters are entered in a row.
Pressing this 'Cancel' key cancels the input and closes the touch keypad.
Pressing the 'Enter' key confirms the input and the input field accepts the entered string.
The spacebar is located on the lower right of the touch keypad.
4.8 Advanced Control of Screen Elements
Beginning with version 2.1, Visual Components input and output fields have some new, common control
possibilities available for the controller application. Because of this, the visualization project can be adapted to
the controller application's processes and states.
4.8.1 Recommendations for New Users
The topics in this section require knowledge about configuring fields and operating the Visual Components
editor.
This information can be found in the following sections:
• Getting Started with Visual Components 2.1
Creating a Visual Components project is described step−by−step in this section.
• Working with the Visual Components Editor
This section contains an introduction and explanation of the individual Visual Components editors and
their dialog boxes.
• Arranging Static Picture Components
This section describes how static picture elements are used for picture layout. They include static texts,
lines, circles, rectangles, and bitmaps.
• Configuring Output Fields for Data
Outputting data is described in this section (output fields). Numeric, text, and graphic output are all
described in this section.
• Configuring Input Fields for Data
This section describes how to configure and use input fields. It also describes the differences between
touch system input and conventional systems which use operator panel keys.
4.8.2 Changing Colors Using Variables
Introduction to Visual Components 2.3
Normally, color for visualization picture elements is set in the editor during the design phase. Global color
settings for frequently used colors are also set in the editor, but can be adjusted for each individual picture
element.
If it is necessary to change the color of a picture element during runtime, it can be done using a color variable.
