(S1)
Data which will be ANDed bit-by-bit
(S2)
(1) The bit-by-bit logical product of the data specified with (S1) and the data specified
with (S2) is found.
(2) When (S1) and (S2) differ in data type, the data of the smaller data type is
converted into that of the greater type before operation is performed. At this time,
note that signed data is converted.
(1) An operation error will occur if:
• (S1) or (S2) is an indirectly specified device and its device No. is outside the
range.
(1) Program which ANDs #0 and #1 and substitutes the result to D0
D0 = #0 & #1
