Data Code Specifications
Whether the read or write data is treated as ASCII (or JIS 8 code) or hexadecimal values is specified in the
command.
■
ASCII (JIS 8 Code)
• One character of ASCII (JIS 8 code) data occupies 1 byte (1
address) of Data Carrier memory.
■
Hexadecimal Code
• One character is treated as a hexadecimal number. Therefore,
only numerals 0 through 9 and A to F can be accepted.
• Two characters of data occupy 1 byte (1 address) of Data Carrier
memory. Therefore, specify data in 2-character units (in even
numbers) when using a Write Command. If an odd number of
characters is specified by mistake, an error will occur.
