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 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
 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
 FOR※ instruction is used for parallel connection with contacts.
API No.

 When both X2 and M30 are On and the content in D100(D101) ≥ F1.234, M60 =
