This chapter tells you:
•
how the ASCII Display object functions
•
about special characters and control sequences
•
which characters are in the ASCII character set
•
about invalid control sequences
•
how to configure the ASCII Display object
The ASCII Display object is used to display on the PanelView
terminal a character string sent from the PLC. The display is updated
whenever the string changes.
The ASCII Display object can display any character in the IBM
extended character set. Special control characters can be included, to
provide special formatting for the displayed characters. The
characters displayed are controlled exactly as specified by the data in
the string. Characters are processed sequentially until a null character
(all bits 0) is received. Any characters after a null character are
ignored.
The maximum character string length is 82 characters.
If only 10 displayable characters (not control characters) are in the
string, only 10 positions on the screen will be filled. Any previously
existing text anywhere else within the display area will be
unaffected.
Words wrap within the area defined for the ASCII Display object,
but if the character string is too long to be displayed, the extra
characters are ignored.
