A.8 TD 200 Simplified Chinese Character Set
The TD 200 supports the Simplified Chinese character set (GB2312–80) for the
People’s Republic of China. The TD 200 uses Microsoft Windows encoding for this
character set. The Windows encoding allows the TD 200 to display the same
characters as shown in the STEP 7– Micro/WIN TD 200 Wizard when you are
using a Chinese emulator or a Chinese version of Microsoft Windows.
Chinese characters are represented in STEP7–Micro/WIN by a pair of numbers
which represent the row and column positions of the character in the GB2312–80
specification. The TD 200 also uses a pair of numbers to represent the Chinese
character.
If you are using a version of STEP 7–Micro/WIN which does not support entering
Chinese characters into the wizard, you can convert the GB character number to
the Microsoft Windows character number and enter these numbers directly into the
data block.
To convert a GB character to the Windows character number, add 160 to each of
the numbers in the GB pair.
Example: The GB number for a character is “42,23”. Add 160 to each
number of the pair to get “202, 183”. Enter these numbers into the data
block.
Figure A-1 shows a sample data block with one message containing the text string
“abcdefg” starting at VB34. Figure A-2 shows the data block modified to replace
the “ab” of the text string with a Chinese character.
Note
Chinese characters require 2 bytes to represent each character. When replacing
text characters in the data block, always replace two text characters with the two
numbers representing the Chinese character.
The alternate character set must be set to Simplified Chinese to allow the TD 200
to display Chinese characters.
