Explanations:
1. This instruction compares the content in S 1 and S 2 . 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
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. FOR※ instruction is used for parallel connection with contacts.
