Screen 1:
Screen 1 illustrates the activation of the message texts using
the associated variable. The output of two different texts in
one message text element is demonstrated. The first screen
contains four message text elements. These are triggered in
succession via the outputs Q1 to Q4 and appear in the
display.
The Message texts tab defines which message is to be
output for a particular state of the associated variable. In this
example, the message “no data” will be output when Q1 =
0, and “Information” will be output when Q1 = 1. All other
message texts elements have only one message text that is
displayed when the corresponding output Q… = 1.
