A.9 Simplified Chinese Character Set
Simplified Chinese Character Set
The TD devices support the Simplified Chinese character set (GB2312-80) for the People's
Republic of China. The TD devices use Microsoft Windows encoding for this character set.
The Windows encoding allows the TD devices to display the same characters as shown in
the STEP 7-Micro/WIN Text Display wizard when you are using a Chinese emulator or a
Chinese version of Microsoft Windows.
Chinese characters are represented in STEP 7-Micro/WIN by a pair of numbers which
represent the encoding of the character in the GB2312-80 specification. The TD devices also
use a pair of numbers to represent the Chinese character.
Notes for Using the Simplified Chinese Character Set
Tip
The Simplified Chinese character set requires a Chinese version of Windows or a Chinese
emulator to properly display Chinese characters in the Text Display wizard. You must start
the Chinese emulator before you start the STEP 7-Micro/WIN software.
On the TD 200C and the TD 200, you can display up to 20 single-byte characters per line of
your message. Because Simplified Chinese uses double-byte characters, you can display up
to 10 double-byte characters per line for a message in Chinese.
On the TD 100C, you can display up to 16 single-byte characters per line of your message.
Because Simplified Chinese uses double-byte characters, you can display up to 8 double-
byte characters per line for a message in Chinese.
On the TD400C using a small font, you can display up to 24 single-byte characters per line
of your message. Because Simplified Chinese uses double-byte characters, you can display
up to 12 double-byte characters per line for a message in Chinese. If you selected a large
font, you can display up to 16 single-byte characters or 8 Chinese characters.
The standard ASCII characters, such as numbers, punctuation, and upper and lowercase
alphabet characters, are available when using the Simplified Chinese character set (shown
below). Depending on your keyboard and/ or emulator, some of these standard characters
may be formatted as single-byte characters instead of the double-byte characters like the
Simplified Chinese characters. Standard ASCII characters and Chinese characters can be
mixed on the TD display.
The Text Display wizard displays 8 , 10, or 12 double-byte character places for the text of a
screen or alarm. You can fit any of the following combinations into a character position:
● 1 double-byte character
● 2 single-byte characters (standard ASCII)
● 1 single-byte character and 1 single-byte blank
You cannot fit one single-byte character plus one double-byte character in a character
position.
