AND, ANI
Outline
AND and ANI instructions connect one contact in series.
The number of contacts connected in series is not limited, so AND and ANI instructions can be used
consecutively as many times as necessary.
Output to another coil by way of a contact after OUT instruction is called cascade output.
Such cascade output can be repeated as many times as necessary as far as the order is correct.
