7.3 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 the OUT instruction is called cascade output.
Such a cascade output can be repeated as many times as necessary as long as the order is correct.
1. Instruction format
→ For the number of instruction steps, refer to Section 7.15.
2. Applicable devices
S1: Special auxiliary relays (M) and 32-bit counters (C) cannot be indexed with index registers (V and Z).
