Function

•Substitutes “1” when s1 is equal to s2 and otherwise “0” into d, assuming s1 and s2 as binary data.

Notes

•The combinations of d, s1 and s2 are as follows:

		d			s1				s2

		Bit			Word			Word

		Bit			Double word	Double word


Program example
									[
			M0000 = WX0000 = = WX0001

										M0000 = WX0000 = = WX0001
										M0000 = WX0000 = = WX0001
									]

Program description

•When WX0000 = WX0001, M0000 is set to “1.” Otherwise, M0000 is reset to “0.”
