Operands:
S
1
: Source device 1 S
2
: Source device 2
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.
FOR※ instruction is used for parallel connection with contacts.
