Description
 S
1
: source device 1
S
2
: source device 2
 This instruction is to compare S
1
and S
2
, if the result ≠ 0, the continuity of the instruction is
enabled; if the result = 0, the continuity of the instruction is disabled.
 LD# (#: &, |, ^) instruction is used for direct connection with busbar
API No.

 &: logical operation with AND operator
 |: Logical operation with OR operator
 ^: Logical operation with XOR operator
Example
 C1 and C10 perform “AND” logical operation, if the result is not 0, Y10 = ON
 D200 and D300 perform “OR” logical operation, if the result is not 0 and X1 = ON, then Y11 =
ON and hold.
