Explanation
1. S
1
: Data source device 1 S
2
: Data source device 2
2. This instruction compares the content in S
1
and S
2
. If the result is not “0”, the
continuity of the instruction is enabled. If the result is “0”, the continuity of the
instruction is disabled.
3. LD# (#: &, |, ^) instruction is used for direct connection with BUS.

4. &: Logical “AND” operation
5. |: Logical “OR” operation
6. ^: Logical “XOR” operation
Example
1. When the result of logical AND operation of C0 and C10 ≠ 0, Y10 = On.
2. When the result of logical OR operation of D200 and D300 ≠ 0 and X1 = On,
Y11 = On will be retained.
