Warning:
This function is not suitable for jog key (momentary) operation. Jog keys have to be transferred using a VISAPI
library function block (see also VA_GetKeyMatrix).
Transfer LED Matrix:
In addition to configuring LEDs individually, LED information can also be transferred using a byte array.
However, only one method can be selected. Otherwise inconsistencies will occur. This information is read
asynchronously.
Change Picture From PLC:
A certain picture can be selected from the control application using this variable. For example, this could allow
certain pictures to be displayed or locked if an error occurs during runtime. If the picture change is successful,
then the interpreter writes the value 65535 to this variable (handshake for picture change). This variable should
only be defined once for a picture change (non−cyclic).
The number of the next picture (to be changed to) can be read in the Picture Overview.
Transmit Current Picture Number:
The number of the currently displayed picture can be transferred to the control application. The picture number
can be read in the Picture Overview.
This number is changed when a picture is inserted or deleted.
Enable Text Layer Switching:
Text layers can be switched by the control application. Each text layer is assigned an index number in the
Language Manager. This index number is the value for enabling a certain language.
Transfer Current Key Level:
Certain panels support up to 4 levels of key assignment. This active key assignment can be changed by other
keys. The variable defined here gives information about which key assignment is active at the moment.
Disable Cursor Movement On Enter:
By default, the next input field is selected after pressing the Enter key. Using this option, the Enter key can be
suppressed in the entire project. The cursor remains on the current input field after Enter has been pressed.
This allows a new value to be given immediately. The next field is selected using appropriate Key Functions.
Activate Alphanumeric Level:
A keypad assignment level can be predefined for alphanumeric input. The runtime system recognizes
alphanumeric entries and uses the defined key level. Alphanumeric characters must first be configured for this to
function properly.
Activate Automatic Comma Input:
For input fields which contain decimal places, the entry is automatically advanced by the number of decimal
places. If 2 decimal places are defined in a field, then an entry of 5−0−0 is converted to the value '5.00'.
If this option is not selected, 5−0−0 is converted to a value of '500'. A decimal point key must then be defined (if
not already).
Colors:
This button provides the default color settings of a project.
Keyboard:
Introduction to Visual Components 2.3
A standard PC/AT keyboard can be defined as an input device when the 'AT Keyboard' option field is selected.
The 'Layout' field defines which keyboard layout should be used.
