Operands:

: Source device 1 S

: Source device 2

Explanations:

1. This instruction conducts logic operation between the content in S

and S

. 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.

2. LD# (#: &, |, ^) instruction is used for direct connection with Left bus bar.

API No.

3. Operation:

& : Logic “AND” operation, | : Logic “OR” operation, ^ : Logic “XOR” operation

4. When 32-bit counters (C200 ~ C254) are used in this instruction, make sure to adopt 32-bit

instruction (DLD#). If 16-bit instruction (LD#) is adopted, a “program error” will occur and the

ERROR indicator on the MPU panel will flash.

Program Example:

1. When the result of logical AND operation between C0 and C10 ≠ 0, Y20 = ON.

2. When the result of logical OR operation between D200 and D300 ≠ 0 and X1 = ON, Y21 = ON

and latched.
