Example program 3 – message text with a display change
The program consists of two screens containing message
texts. The screens are activated automatically in succession
in the display. This program is an extension of the program
Message_Text_02. The extension consists of two messages
being contained in one message text element in screen 2,
which are also toggled automatically. A display change is also
executed in one message text. 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 make contacts
(C01ZE) of the counter in the circuit diagram are switched
directly before the outputs Q1 to Q4 as well as before LE 3.
The outputs are only meant to be active with screen 1, i.e.
when the counter has the value 0.
The screens are activated via counter C01. This has the value
2 as the upper setpoint SH, thus providing the counter values
0, 1 and 2. Counter value 0 activates mask 1, counter value 1
activates the first message text in screen 2 and counter value
2 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. If the counter C01 reaches its
upper setpoint with the second pass, this starts the on-
delayed timing relay T08. This then resets the counter C01 to
0 after the set time has elapsed (0.8 s). This loop is repeated
continuously.
