# Overview

This part of the ASCET online help describes how to work with signals and icons in the ASCET database or workspace. Signals and icons are supplementary data for a control system that can be stored together with the system itself in the ASCET database or workspace.

Both signals and icons can be imported into the database or workspace or exported to the file system. Signals are used by the system, icons can be assigned to elements and hierarchies. The following links explain how to work with each type of item.

## Signal Viewer

_Source: `markdown/SI_signal_viewer.md`_

# Signal Viewer

With the signal viewer signals can be loaded into the ASCET database or workspace and viewed. The viewer can read a variety of signal formats and convert signals between formats.

The following measurement data formats are supported by ASCET:

- Tab delimited ASCII. Almost every spreadsheet or database can read and write in this format.
- FAMOS Channel Format.
- FAMOS Record Format.
- Matlab Source Code Format (i.e., *.m).
- MDF V2.00 Format.

ASCET can import MDF V2.* and MDF V3.* files, but the enhancements of higher versions are ignored.

The last four are third-party formats for measurement data. Please refer to the relevant documentation for details. Internally, ASCET can process the ASCII format and both types of FAMOS format. MDF and Matlab source code format can be read and written.

## Icon Editor

# Icon Editor

Icons can be assigned to the layout of components. The icon is shown in the graphical block, when the component is included in other components in the block diagram editor. A selection of icons is provided with ASCET, and you can also create your own.

## Loading an Image

_Source: `markdown/SI_load_icon.md`_

# Loading an Image

You can load an image file with BMP, JPG or TIFF format and use it as an icon in ASCET. Thus, you can either design your own icons with a drawing program, or use existing ones. You should make sure that the images you are importing are of an appropriate size, i.e. no larger than the graphical block the icon is to be assigned to. One grid unit in ASCET corresponds to 10 pixels.

Progressive JPEG images cannot be used for ASCET icons. You must convert such a file to normal JPEG before you can import it.

To load an image into an icon, proceed as follows:

1. Open the icon in the icon editor.
1. In the icon editor, open the Icon menu and select Load.
1. Select the name of the image file you want to load.
1. Click Open.

The selected image is displayed in the icon editor.

## Scaling an Icon

_Source: `markdown/SI_scale_icon.md`_

# Scaling an Icon

Icons can be scaled up or down to make them fit the block in which they are to be used. Scaling will, however, result in a degradation of image quality. Scaling by large factors should therefore be avoided.

To scale an icon, proceed as follows:

1. Open the icon editor for the icon you want to scale.
1. Adjust the vertical and horizontal size of the icon with the two Size boxes underneath the icon pane.
1. Click OK.

## Saving an Icon to a File

_Source: `markdown/SI_save_icon.md`_

# Saving an Icon to a File

It is possible to save ASCET icons as bitmap files. This is useful, for instance, if you want to illustrate the documentation of your components.

To save an icon to a file, proceed as follows:

1. Open the icon editor for the icon you want to store to a file.
1. In the Icon menu, point to File Out and select <file format>.
1. Select the filename and the path where you want to save the icon.
1. Click Open.

The icon is stored in the selected format (BMP, JPG or TIF).

## Signal Viewer

_Source: `markdown/SI_View_Signal_Item_Window.md`_

# View Signal Item Window

The View Signal Item window (i.e. the signal viewer) contains the following elements:

- [File](markdown/SI_File_Menu.md) Menu
- [Navigation](markdown/SI_Navigation_Menu.md) Menu
- [Toolbar](markdown/SI_Toolbar.md)

Here, the signal is displayed as a table. The first column contains the data labels, the first row contains timing information. The table can show up to 1000 data columns at a time; the number can be adjusted in the ASCET options, Signal Editor node. If the signal contains more data, use the Navigation menu or the toolbar to display them.
