6. Function blocks
6.1 Manufacturer function blocks
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
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 8, 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. and can be used to add graphic mac-
ros, texts, value displays, bar graphs, running texts, mes-
sage texts, date and time entries, etc. on the work pane.

Input options
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
function block input is used to call the function block in the
program, 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 priorities to change from one enabled function block to the next every time
after the set rolling time elapses.
