Rolling text:
Rolling texts can be used to display various texts in succession in a single line. This can
come in handy, for instance, for operating or maintenance procedures in which the dis-
play needs to ask the operator or maintenance technician to carry out a step, then
another step, then another, etc. In this case, the text can be changed every time the
operator or maintenance technician performs the requested action (shift register).
The required texts need to be entered into the table under the Rolling text tab, where
you can also select the corresponding colors and the display type.
Unconditional display:
When this operating mode is selected, the texts will be displayed in succession at the
specified interval. This interval can be defined using the Display time parameter.
Associated variable
When this operating mode is selected, the text selection will depend on the application
program. More specifically, an operand that can be selected under the Associated vari-
able tab will be used to control how the texts are displayed. You can select local or net-
work operands of type byte, word, or double word. Each text will then be automatically
linked to a bit from the selected operand as you enter it.
l
Text 1 will be assigned bit 1
l
Text 2 will be assigned bit 2
l
Text 3 will be assigned bit 3
l
etc.
If bit 2 is set in the program at runtime, for example, text 2 will be displayed. If multiple
bits in the operand are set simultaneously, the corresponding texts will be displayed in
