Function

zSubstitutes 1 when s1 is not equal to s2 and otherwise 0 into d, assuming s1 and s2 as signed binary data.

zs1 and s2 are both signed binary data. When the most significant bit is 0, the value is positive; when the most significant bit is 1, the value is negative.

s1, s2 – 2147483648 to +2147483647 (decimal) H80000000 to H7FFFFFFF (hexadecimal)


b31	b16 b15		b0

	Sign bit: 0 - Positive; 1 - Negative

Program example

Y00100 = DR0000 S<> DR0002Y00100 = DR0000 S<> DR0002

]

Program description

z When the values of DR0000 and DR0002 are not equal, Y00100 is turned on. Otherwise, Y00100 is turned off.

d = s1 S<> s2
