Info

If the Use Global option is selected, then colors defined in the global project settings are used. If this option is not selected, text and background output color can be specified using the Foreground and Background settings. A variable which allows colors to be changed during runtime can be connected under Colors Variable (see also Changing Colors Using Variables). 4.6.4.1.8 Simulation A text can be entered here which is displayed in the editor in Simulation mode. 4.6.4.2 ListBox This output field is very similar to the Advanced Text output field. However, several texts are shown simultaneously in a list with the currently selected text accentuated by a different color. The ListBox is conceived as an output field and therefore does not receive any user interaction. The selected text is determined by a process variable from the PLC program. In this way, touch−operated elements can very easily implement any desired operation in the application if a panel with a touch screen is used. Naturally, key operation can also be implemented easily. ListBox properties correspond in many ways to those of Advanced Text Output. Different settings for the ListBox will be described in the following. 4.6.4.2.1 Format In addition to the format properties of Advanced Text, the number of ListBox lines can be determined using the Rows parameter. 4.6.4.2.2 Source of Texts There are 2 possibilities to choose from when displaying text with the ListBox: Introduction to Visual Components 2.3 An existing text group can be connected using the Text Group setting. All texts from this text group are displayed in the ListBox during runtime in the order they were entered. The sequence or number of texts cannot be changed dynamically at runtime. However, text numbering within the text group can be adjusted during the design phase in the text group editor to meet corresponding requirements. 334 4.6.4.1 Advanced Text Output
Introduction to Visual Components 2.3 Texts are output from an array of string variables if the second setting, String Array, is selected. These texts can be composed in the control application during runtime and then output dynamically. Each line corresponds to a string from the array of strings. It should be noted that a string is an array by default. Therefore, an array of arrays must be created for this process variable. In contrast to the Text Group setting, switching languages between the text layers defined in Visual Components cannot be applied (since texts are only made available during runtime from the PLC program and are therefore not recognized by the Visual Components editor). Language switching must be disabled by the control application if necessary. 4.6.4.2.3 Variables The Selected Item setting selects the highlighted line from the list. The list is always automatically advanced so that the element is visible. 4.6.4.2.4 Colors In addition to color settings for Advanced Text, the color of the highlighted line in the ListBox also has to be set. 4.6.4.3 Bitmap Graphic This output field uses bitmaps to represent a dynamically changing status. For this, a process variable from the PLC program can be used to switch between up to 255 different bitmaps. The upper−left corner of the bitmap is always located at the specified position of the bitmap output field. The background is not cleared when bitmaps are switched. Instead, only the new bitmap is output. Therefore, all bitmaps should be the same size so that the rest of the previous bitmap does not remain on the display when it is switched. At the moment, bitmap output is only possible on IPC target systems (in color or black/white depending on the display) or the PP41 PowerPanel. Displays used by the C130 CAN controller do not support bitmap output fields. The following settings can be defined for the bitmap field under the 'Parameter' tab: 4.6.4.2 ListBox 335
