Operation processing
1.
AND(_E)
• These functions perform an AND operation (bit-by-bit) on the BOOL, WORD, or DWORD data type values input to (s1) to
(s28), and output the operation result, in the same data type as (s), from (d).
Ex.
Data type: WORD
2.
OR(_E)
• These functions perform an OR operation (bit-by-bit) on the BOOL, WORD, or DWORD data type values input to (s1) to
(s28), and output the operation result, in the same data type as (s), from (d).
Ex.
Data type: WORD
3.
XOR(_E)
• These functions perform an XOR operation (bit-by-bit) on the BOOL, WORD, or DWORD data type values input to (s1) to
(s28), and output the operation result, in the same data type as (s), from (d).
Ex.
Data type: WORD
• If three or more (s) settings exist, (s3) will be XORed with the result of XOR between (s1) and (s2). In addition, if (s4) exists,
(s4) will be XORed with the result of subjecting (s) to XOR. After this, XOR will repeat for the number of (s) settings.
Ex.
Data type: BOOL
(1) Number of s's: 3
(2) Number of s's: 4
(3) Number of s's: 5
The XOR operation is repeated by the number of s's.
