Bitmap Example Program 3 – Overlaying Bitmaps
The program consists of three screens that you can select via the up and down
cursor buttons. The screen change is defined in the Button editor (see Button
Editor on page 5-37).
This program illustrates the overlaying of bitmaps in a screen. The circuit
diagram uses six on-delayed timing relays (T01 to T06), that activate outputs
Q1 to Q4 and LED 3 in succession after an elapsed time. This operation is run
in a continuous loop since timing relay T06 resets all timing relays after a set
time.

Program: Bitmap_automatic screen change.e60
Screen 1 - The first screen contains five half-overlaid bitmaps. These are
activated via the outputs Q1 to Q4 and marker M01, and appear in the display.
The half overlaid bitmaps are activated in succession. The Covered option is
selected in the Background area of the Display tab, therefore causing the
overlaid part of the bitmap to be covered by the bitmap in front of it. In this
way it is possible to create the impression of a moving arrow.

Screen 2 - The second screen contains five overlaid bitmaps with each
subsequent bitmap being larger than the previous one displayed. The
individual bitmaps are made visible in succession via the outputs Q1 to Q4 and
the marker M01 (break contact bit logic). The Covered option is selected in the
Background area of the Display tab, therefore causing the overlaid part of the
bitmap to be covered by the bitmap in front of it. In this way it is possible to
create the impression of a moving and expanding arrow.

Screen 3 - The third screen contains five fully overlaid bitmaps. These are
made invisible in succession from the top to the bottom via the outputs Q1 to
Q4 and the LED 3 (make contact bit logic). The Covered option is selected in
the Background area of the Display tab. The overlaid section of the bitmap is
therefore not visible.
