Function
• Substitutes the content of s into d.
• It is possible to use array variables for d and s.
• When d is a word, the constant is 0 to 65535 or – 32768 to + 32767 (decimal)
H0000 to HFFFF or H8000 to H7FFF (hexadecimal)
When d is a double word, the constant is 0 to 4294967295 or -2147483648 to +2147483647 (decimal)
H00000000 to HFFFFFFFF or H80000000 to H7FFFFFFF
Notes
• When using an array variable, DER is set to 1 if the usable I/O number exceeds the maximum value, and DER is reset to “0”
if it is normal.
• The combinations of d and s are as follows:
