  Pulse instruction  16-bit instruction (5 steps)
32-bit instruction (5 steps)
Symbol: 
 
Taking AND& and DAND& for example 
S

:
Data source 1  Word/Double word 
S
2
 
:
Data source 2  Word/Double word 
Explanation: 
1.  The instruction is used to compare the data in S
1
 with that in S
2
. When the comparison result is 
not 0, the condition of the instruction is met. When the comparison result is 0, the condition of 
the instruction is not met. 
2.  Only the instruction DAND#  can use the 32-bit counter. 
3.  The instruction AND#  and the contact are connected is series.

4.  &: Logical AND operation 
5.  |: Logical OR operation 
6.  ^: Logical exclusive OR operation 
Example: 
1.  When X0.0 is ON, the logical operator AND takes the data in C0 and C10, and performs the 
logical AND operation on each pair of corresponding bits. When the operation result is not 0, 
Y1.0 is ON. 
2.  When X0.1 is OFF, the logical operator OR takes the data in D10 and D0, and performs the 
logical OR operation on each pair of corresponding bits. When the operation result is not 0, 
Y1.1 keeps ON. 
3.  When X0.2 is ON, the logical operator XOR takes the data in the 32-bit register (D200, D201) 
and the data in the 32-bit register (D100, D101), and performs the logical exclusive OR 
operation on each pair of corresponding bits. When the operation result is not 0, or when X0.3 
is ON, Y1.2 is ON.
