Symbol:
Taking LD& and DLD& for example
Explanation:
1. The instruction is used to compare the data in S
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 DLD＃ can use the 32-bit counter.
3. The instruction LD＃ can be connected to the mother line directly.

0811
4. &: Logical AND operation
5. |: Logical OR operation
6. ^: Logical exclusive OR operation
Example:
1. The logical operator AND takes the data in C0 and C1, and performs the logical AND operation
on each pair of corresponding bits. When the operation result is not 0, Y1.0 is ON.
2. The logical operator OR takes the data in D200 and D300, and performs the logical OR
operation on each pair of corresponding bits. When the operation result is not 0 and X1.0 is ON,
Y1.1 is ON.
3. The logical operator XOR takes the data in C201 and C200, and performs the logical exclusive
OR operation on each pair of corresponding bits. When the operation result is not 0, or when
X1.1 is ON, Y1.2 is ON.
