Operands:

S1: Source device 1 S2: Source device 2

Explanations:

1.This instruction compares the content in S1 and S2. Take “FAND =” 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.The user can specify the floating point value directly into operands S1 and S2 (e.g. F1.2) or store the floating point value in D registers for further operation.

3.FAND※ instruction is used for serial connection with contacts.

API No.	32-bit instruction	Continuity condition	Discontinuity condition
281	FAND＝	S1＝S2	S1≠S2
282	FAND＞	S1＞S2	S1≦S2
283	FAND＜	S1＜S2	S1≧S2
284	FAND＜＞	S1≠S2	S1＝S2
285	FAND＜＝	S1≦S2	S1＞S2
286	FAND＞＝	S1≧S2	S1＜S2

Program Example:

When X1 is OFF and the content in D100(D101) is not equal to F1.2, Y21 = ON and latched.

FAND<> F1.2 D0 SET Y21
