Operands:

S1: Source device 1 S2: Source device 2

Explanations:

1.This instruction conducts logic operation between the content in S1 and S2. 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.	16 -bit	32 -bit	Continuity
	instruction	instruction		condition
215	LD&	DLD&	S1	& S2≠0
216	LD	DLD	S1	S2≠0
217	LD^	DLD^	S1	^ S2≠0

Discontinuity

condition

S1 & S2＝0

S1 S2＝0

S1 ^ S2＝0

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.

LD &	C0	C10		Y20
