Example program 2 – Controlling message texts with
timing relay
The program consists of two screens containing message
texts. The screen activation automatically shows the screens
on the display in succession. The circuit diagram uses six on-
delayed timing relays (T01 to T06) that activate outputs Q1
to Q4 as well as LE 03 in succession after the elapsed time.
The operation is carried out in a continuous loop since the
timing relay T06 resets all timing relays after the set time.
The screen activation is implemented via counter C01. This
contains the value 1 as the upper set value SH. This therefore
produces the counter values 0 and 1 that are used for both
screens as activation values. When the timing relays T01 to
T06 are reset by T06, counter C01 is activated which reaches
the status value 1 and therefore its upper set value, causing
screen 2 to be displayed. The on-delayed timing relay T08
sets the counter C01 back to zero after the set time (0.8 s),
causing screen 1 to be displayed again the timing relay T08
is no longer activated. The loop is continued.

Screen 1:
The first screen shows four bit message text elements. These
are triggered in succession via the outputs Q1 to Q4 and
appear in the display.
Screen 2:
The second screen contains a message text element with a
message text.
