Clearing the display
When sending a command to display a message, a previously defined user
message is not cleared. The new message starts at the end of the old message
on that line. It is good practice to routinely clear the display before defining a new
message.
After displaying an input prompt, the message will remain displayed even after the
operator performs the prescribed action. The
clear function must be sent to clear
the display.
The following command clears both lines of the display, but does not affect any of
the annunciators:
display.clear()
Cursor position
When displaying a message, the cursor position determines where the message will
start. On power-up, the cursor is positioned at Row 1, Column 1 (see
Figure 14-1). At
this cursor position, a user-defined message will be displayed on the top row (Row 1).
Top line text will not wrap to the bottom line of the display automatically. Any text
that does not fit on the current line will be truncated. If the text is truncated, the
cursor will be left at the end of the line.
NOTE The display.clear, display.setcursor, and
display.settext functions (which are explained in
the following paragraphs) are overlapped, non-blocking
commands. The script will NOT wait for one of these
commands to complete.
These non-blocking functions do not immediately update
the display. For performance considerations, they write to
a shadow and will update the display as soon as process
-
ing time becomes available.
