
The instruction is used to compare the value in S with that in S
1
, and
compare the value in S with that in S
2
. The comparison result is stored in
D .

S
1
: Minimum value; S
2
: Maximum value; S : Comparison value; D :
Comparison result

The value in S
2
must be greater than that in S
1
.

The operand D occupies three consecutive devices.


When X0.0 is ON, the instruction ZCP is executed, and M0, M1, or M2 is
ON. When X0.0 is OFF, the execution of the instruction ZCP stops, and
the states of M0, M1, and M2 remain unchanged
.

If the operand D is M0, M0, M1, and M2 will be occupied automatically.
