String Library
Use String Library to store text strings within the controller's FLASH memory,
and then display them on the controller's LCD. You can, for example, organize
text into different String Libraries—for example, separate libraries for Spanish,
English and Italian—pull strings into HMI objects, and then switch libraries to
change the display language.
These strings can be displayed in the following HMI elements:
Frame
Button
Fixed Text
String Libraries also provide the text for Alarms, and can be used in Trend
Curve Properties.
There are:
16 String Libraries containing up to 1024 strings each. You can change the
library default names.
Via String Library> File, you can opt to use only 4 or 8 libraries; in this
case the total number per library is 2,046 strings.
Note that each library contains sections in the 3,000 range, that are
‘greyed'; these are reserved for system use.
Each string can contain up to 128 characters.
The total memory capacity for all String Libraries is 64K.
This feature is not available in
Standard Vision controllers.
How String Library works
Only one library is active at a time. This means that at any given time, all
elements that pull text from a library are using the same library.
However, each HMI element may be linked to a different line ID # within that
String Library.
In the following figure, the buttons are linked to different text lines. Each time
a different String Library is called, the button text changes.
