Example

Coding

To turn ON 0503, 0002 must be ON, 0003 OFF, and 0004 ON at the same time. The
AND and ANB instructions are used when two or more conditions (in this case,
0002: ON, 0003: OFF, 0004: ON) must be satisfied at the same time.

Description

As many contacts as desired can be connected in series provided these contacts
are used in the same program.

As OUT 0503 shown in the above example, when an AND or ANB instruction is
used immediately after an OUT instruction to connect the other relay via a
contact (0004 in the example), the AND or ANB can be used as many times as
desired, provided the program syntax is correct.

The following two circuits operate in the same manner, but the coding for these
circuits are different.
