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.
3. FOR※ instruction is used for parallel connection with contacts.
