Using a Status Chart to Monitor and Modify Your Program
As shown in Figure 4-16, you can use a Status Chart to read, write, force, and
monitor variables while the program is running. Use the menu command View >
Status Chart.
• The status chart toolbar icons are shown in the STEP 7-Micro/WIN 32 toolbar
area. These toolbar icons (Sort Ascending, Sort Descending, Single Read,
Write All, Force, Unforce, Unforce All, and Read All Forced) are enabled when
you select the status chart.
• You can create multiple status charts.
• To select a format for a cell, select the cell, then press the right mouse button to
enable the drop-down list (Figure 4-16).
