Please refer to the specifications of each model for the
range of operands.
 S1: Source device 1 S2: Source device 2
Explanation
 This instruction compares the content in S
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.
 FLD※ instruction is used for direct connection with left hand bus bar.
API No.

 When the content in D100(D101) ≤ F1.2 and X1 is ON, Y21 = ON and latched.
