Fundamentals of COM 266
Figure 6-22 shows the hierarchical structure of the "TEST" form.
There are two "TEST" modes:
When the "TEST" function is invoked, COM 266 is in the "Actual-value display"
mode. The default operating mode is the "FOLLOW-UP" mode (mode 4). This
mode has not been started, however. The output fields in the data area are not
yet updated.
The second "TEST" mode is "Mode Select". In this mode, you can make changes in
the screen form's input fields.
