Indicates that D350 stores
"56ABH ("22187" in decimal)".
Use capitalized code for alphabetical letter.
When data other than integer value (real number, character string), is stored in the word device memory for
reading data, the stored value are read as integer value.
(Example 1) When a real number (0.75) is stored in D0 to D1, the value is read as the following integer value.
• D0 = 0000H, D1 = 3F40H
(Example 2) When a character string (12AB) is stored in D2 to D3, the character string is read as the following
integer value.
• D2 = 3231H, D3 = 4241H
Data in word units handled when reading and writing buffer memory areas is expressed in the same way as
the word device memory.
