Explanation
S1: Source device 1 S2: Source device 2
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.
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.
FAND※ instruction is used for serial connection with contacts
