Associated variable tab - On the Associated variable tab you define the
variable with the value for activating the output text.
Message texts tab - Assign in the Message texts tab the value of the
associated variable for its corresponding message text, and select the language
and the default text.
Visibility tab - The Visibility tab enables you to make the screen element
invisible via an associated variable.
Display change tab - The Display change tab offers the following display
forms of the message, which can be controlled with an associated variable:
• flashing
• Inverted
Message Text Example Program 1 – Activating Message Texts with a Boolean
Variable
The program consists of seven screens that can be selected using the up and
down cursor buttons. The screen change was defined in the Button editor (see
Button Editor on page 5-37). The circuit diagram uses six on-delayed timing
relays that activate outputs Q1 to Q4 and LED03 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 message texts are controlled in all
screens by means of Boolean variables. As these only have two states (0/1),
only two different messages can be output via each message text element. If
other variable types are used, the number of possible message texts can be
increased accordingly.

Screen 1 - Screen 1 illustrates the activation of message texts by means of the
associated variable. The output of two different texts in one message text
element is also illustrated. The first screen contains four message text
elements. These are activated via the outputs Q1 to Q4 and appear in the
display.
The Message text tab is used to assign the message to be output with a
particular state of the associated variable. In this example, if Q1 = 0, the
message “no data” is output, and “Information” is output if Q1 = 1. All other
message text elements have only one message text which is displayed when the
corresponding output Q.. = 1.
