Example program 3 – Message text with display
change
The program consists of two screens containing message
texts. The screen activation automatically shows the screens
on the display in succession. This program is an extension of
the program
Messagetext_Prog_02.e60
. The extension
consists of screen 2 containing two messages in one
message text element which are toggled automatically. A
display change is also carried out in one message text. The
circuit diagram uses six on-delayed timing relays T01 to T06
that activate outputs Q1 to Q4 as well as LE 3 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. In the circuit diagram, N/O contacts
(C01ZE) of the counter are switched directly before the
outputs Q1 to Q4 as well as before LE 03. The outputs must
only be active with screen 1, i.e. when the counter is set to 0.
Screen activation is triggered by counter C01. This has the
value 2 as the upper switch value SH. This produces the
counter values 0, 1 and 2. The counter value 0 activates
screen 1, counter value 1 activates screen 2 and counter
value 2 activates the second message text in screen 2. When
the timing relays T01 to T06 are reset, the counter receives
a pulse and is incremented by one value. When counter C01
reaches its upper set value on the second pass, the on-
delayed timing relay T08 starts. After the set time (0.8 s) this
resets the counter C01 to 0. The loop is continued.
