Displaying Special Characters
With the LCD instruction, the LCD screen can display the characters of A
to Z, a to z, 0 to 9, and special characters in the range of ASCII
0x00...0x7F. If an Input character is in the range of ASCII 0x80...0xFF, a
question mark (?) is displayed on the LCD.
Be careful that some special characters are substituted with the
corresponding embedded characters in the LCD. The table below shows
the available character set on the LCD. For information on how to
manipulate a string file for display of special characters, refer to your
RSLogix 500/RSLogix Micro Online Help.
