Operands:

S1: Source device 1 S2: Source device 2

Explanations:

1.This instruction compares the content in S1 and S2. Take “FOR =” 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.FOR※ instruction is used for parallel connection with contacts.

API No.	32-bit instruction	Continuity condition	Discontinuity condition
287	FOR＝	S1＝S2	S1≠S2
288	FOR＞	S1＞S2	S1≦S2
289	FOR＜	S1＜S2	S1≧S2
290	FOR＜＞	S1≠S2	S1＝S2
291	FOR＜＝	S1≦S2	S1＞S2
292	FOR＞＝	S1≧S2	S1＜S2

Program Example:

When both X2 and M30 are On and the content in D100(D101) ≥ F1.234, M60 = ON..

X2 M30

M60

FOR>= D100 F1.234
