3 Description of functions
3-52
• In word units (subcommand: 000, 002)
When performing data communication in ASCII code, send data with 1 word in 4-bit units in the order from
higher-order byte to lower-order byte. Data is expressed in hexadecimal.
Use codes in upper case characters when specifying letters of the alphabet.
When word devices for reading data contain other than integers (real numbers, character strings),
stored values are read as integer values.
● When D0 to D1 contains a real number (0.75), D0 = 0000H, and D1 = 3F40H.
● When D2 to D3 contains a character string ("12AB"), D2 = 3231H, and D3 = 4241H.
