WAND, WANDP, DAND, DANDP
WAND
(1) A logical product operation is conducted for each bit of the 16-bit data of the device designated at
of the device designated at
(2) For bit devices, the bit devices after the points designated by digit specification are regarded as "0" in the operation.
(See Program Examples (1) and (2))
DAND
(1) Conducts a logical product operation on each bit of the 32-bit data for the device designated by
the device designated by
(2) For bit devices, the bit devices after the points designated by digit specification are regarded as "0" in the operation. (See
Program Example (3))
Operation Error
(1) There is no operation error in the WAND(P) or DAND(P) instruction.
Program Example
(1) The following program performs a logical product operation on the data from X10 to X1B and the data at D33 when XA is
ON, and stores the results at D40.
