Operands:

S1: Source device 1 S2: Source device 2

Explanations:

1.This instruction compares the content in S1 and S2. Take API232 (AND =) for example, if the result is “=”, the continuity of the instruction is enabled. If the result is “≠”, the continuity of the instruction is disabled.

2.AND※ (※: =, >, <, <>, ≤, ≥) instruction is used for serial connection with contacts.

API No.	16 -bit	32 -bit	Continuity	Discontinuity
	instruction	instruction	condition	condition
232	AND＝	DAND＝	S1＝S2	S1≠S2
233	AND＞	DAND＞	S1＞S2	S1≦S2
234	AND＜	DAND＜	S1＜S2	S1≧S2
236	AND＜＞	DAND＜＞	S1≠S2	S1＝S2
237	AND＜＝	DAND＜＝	S1≦S2	S1＞S2
238	AND＞＝	DAND＞＝	S1≧S2	S1＜S2

3.When the MSB (16-bit instruction: b15, 32-bit instruction: b31) of S1 and S2 is 1, the comparison value will be viewed as a negative value in comparison.

4.When 32-bit counters (C200 ~ C254) are used in this instruction, make sure to adopt 32-bit instruction (DAND※). If 16-bit instruction (AND※) is adopted, a “program error” will occur and the ERROR indicator on the MPU panel will flash.

Program Example:

1.When X0 = ON, and the content in C10 = K200, Y20 = ON

2.When X1 = OFF and the content in D0 ≠ K-10, Y21= ON and latched.

X0		K200	C10	Y20
	AND=
X1		K-10	D0	SET	Y21
	AND<>
