Storage of word device
• Character codes are stored in word devices in the PLC. The stored data is displayed from
the lower 8 bits as shown below.
Example 1
: When two half-width characters (ASCII codes) are displayed
Word Device : D0
Data Length : 1
- A character to be displayed at first should be specified using lower 8 bits.
Example 2 : When one full-width character is displayed
Word Device : D0
Data Length : 1
Example 3 : When one full-width character and two half-width characters are displayed
Word Device : D0
Data Length : 2 (D0 and D1)

Important point
When the character code is set to "H0" (either for full-width or half-width), characters after that
are not displayed on the screen.
To insert space in a text, store "H8140" (for full-width) or "H20" (for half-width) to the specified
word device.
To display an external character registered in the screen creation software, store "F040" to
"F0C0" to the specified word device.
