6.1.7.3 D - Text display

General
easyE4 base devices provide 32 text display function blocks,
D01 through D32. Each of these function blocks can be used to
output a custom text display on the easyE4 display or on
another external display device and to allow custom input
using the device's P buttons.
Output options
l
Each text display consists of 6 lines, with 16 characters
each. In other words, 96 characters. These displays are
created using a text editor in easySoft 7, and can be used
to add graphic macros, texts, value displays, bar graphs,
running texts, message texts, date and time entries, etc. on
the work pane.
Input options
l
These can be used to enable operators to enter value input
and use input buttons. Specific device P buttons can be
used to implement user controls within this context.
Various character sets, such as Cyrillic, are available, as if the
ability to switch between various user languages. The EN func-
tion block input is used to call the function block in the pro-
gram, and enables the text display.
Operating principle
Only one text display function block instance (i.e., only one of the maximum 32) can be
displayed at any one time. This must be implemented with the programming, i.e., only
one of the text displays should be enabled with the EN input at any one time. If multiple
function blocks are enabled instead, the display priority and rolling time will be used to
determine which one is displayed. In this case, the program will follow the defined pri-
orities to change from one enabled function block to the next every time after the set
rolling time elapses.
