“Associated Variable” tab
Define the Boolean variable on the Associated variable tab
for activating the value for a particular output text.
“Message texts” tab
The Message texts tab is used to assign the value of the
associated variable to the corresponding message text, as
well as to select the language and the standard text.
“Visibility” tab
The Visibility tab makes it possible to switch the element to
invisible via an associated variable.
“Display Change” tab
The Display change tab offers the following display options
which can be controlled via an associated variable:
• Flashing,
• Inverse
Example program 1 – Controlling message texts with
Boolean variables
The program consists of seven screens that you can select via
cursor buttons
Í
and
Ú
. The screen change was defined in
the button editor ( a section “Button editor”, page 317).
The circuit diagram uses six on-delayed timing relays that
activate outputs Q1 to Q4 as well as LE 03 in succession after
the elapsed time. The process is carried out in a continuous
loop since the timing relay T06 resets all timing relays after
the set time. In all screens the message texts are activated
via Boolean operands. As these operands only have two
states (0/1), only a maximum of two different messages can
be output for each message text element. Other variable
types will allow the output of correspondingly more
messages per message text element.
