(2) For bit devices, the bit devices below the points designated by digit specification are
regarded as "0" in the operation.
Operation Error
(1) There are no operation errors associated with the WXOR(P) or DXOR(P) instructions.
Program Example
(1) The following program conducts an exclusive OR operation on the data from X10 to X1B
and the data at D33 when X10 is ON, and outputs the result to from Y30 to Y3B.
[Ladder Mode]
[Operation]
X1B-X10
D33
Y3B-Y30
(2) The following program conducts an exclusive OR operation on the data at D20 and D21, and
the data at D30 and D31 when X10 goes ON, and stores the results at D40 and D41.
[Ladder Mode]
