Operands:
S
1
: Source device 1 S
2
: Source device 2
Explanations:
1. This instruction compares the content in S
1
and S
2
. 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 S
1
and S
2
(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.

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