Explanation
S1: Source device 1 S2: Source device 2
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.
