Groups Tab

Use Groups in an A2L file to help organize Measurements and Characteristics into logical categories. The Groups tab has a table to display all A2L file Groups and their properties. Each row (below the 1st filtering row) defines a Group and each column is a property. The default column configuration is shown in Figure 1.

Figure 1: The Groups tab in the A2L file item area.

Columns in the table can be filtered, reorganized, added, and hidden. These table features are common across all tabs in this area. To add items to the table you can:

• Use the Create tool or right click menu selection.

• Import an existing A2L file.

To edit items already in the table with the Edit Groups dialog you can:

• Double click on a cell in the table.

• Use the Edit tool or right click menu selection.

Refer to Table 1 below for a description of each column on the Groups tab.
