This function converts WORD data In to INT data Out .
Example When Value of Out Is Positive (INT#0 to INT#32767)
• The value of Out is INT#0 to INT#32767 according to the value of In (WORD#16#0000 to
WORD#16#7FFF).
Example When Value of Out Is Negative (INT#
−
32768 to INT#
−
1)
• If the value of In is WORD#16#8000 (1000 0000 0000 0000 binary), the value of Out is INT#32768,
which is INT#
−
32768 as a 2-byte expression.
• If the value of In is WORD#16#FFFF (1111 1111 1111 1111 binary), the value of Out is INT#65535,
which is INT#
−
