Function
WAND
(1) A logical product operation is conducted for each bit of the 16-bit data of the device
designated at
stored in the device designated at
(2) When bit devices are designated, the bit devices below the points designated as digits are
regarded as "0" in the operation. (See Program Example (2))
DAND
(1) Conducts a logical product operation on each bit of the 32-bit data for the device designated
