Screen 6 - Screen 6 is basically the same as screen 5 except that Inverted was
selected for the Display change function. When input I2 = 1 (make contact bit
logic), the message text in this screen can thus be inverted.

Screen 7 - Screen 7 is basically the same as screen 6 except that the inverted
display is controlled by timing relay T07 (asynchronous clock pulse). The text
flashes in the display at different pulse and pause times.

Message Text Example Program 2 – Activating Message Texts with a Timing Relay
The program consists of two screens containing message texts. The screens
are activated automatically in succession in the display. The circuit diagram
uses six on-delayed timing relays T01 to T06 that activate outputs Q1 to Q4
and LE03 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.
The screen activation is executed via counter C01. This has the value 1 as the
upper setpoint SH. The counter values 0 and 1 are therefore used as activation
values for the two screens. The resetting of timing relays T01 to T06 by T06
activates counter C01 which then reaches the value 1 and therefore has already
reached its upper setpoint. This then causes screen 2 to be displayed. The
on-delayed timing relay T08 resets counter C01 back to 0 after the set time (0.8
s) has elapsed. Screen 1 is then displayed again and timing relay T08 is no
longer activated. This loop is repeated continuously.

Screen 1 - The first screen contains four message text elements. These are
activated in succession via the outputs Q1 to Q4 and appear in the display.
Screen 2 - The second screen contains one message text element with one
message text.
