Encoding Details

GENESIS64 uses ASCII encoding as the default setting for reading and writing STRING data. This causes garbled characters when you enter unsupported characters in ASCII encoding, such as Japanese Kanji. You can avoid garbled characters by selecting the appropriate encoding from the Encoding drop-down list under Other Settings in a MELSEC device configuration.

Encoding drop-down list

Supported Encoding

Display Name	Encoding	Language
Not Specified	ASCII	English
Unicode (UTF-16)	Unicode (UTF-16)	Multilingual
Shift_JIS	Shift_JIS	Japanese
GB18030	GB18030	Chinese (simplified)
Big5	Big5	Chinese (traditional)
KS X 1001	KS X 1001	Korean

The encoding setting applies to all STRING data type tags under a device.

The String Length setting is based on ASCII (1-byte characters). Therefore, using an Encoding setting other than Not Specified reduces the number of usable characters by half or even more. Make sure to set the string length large enough to store all characters.
