Operands:
S
1
: Data source value 1 S
2
: Data source value 2
Description:
1. Compare the contents of S
1
and of S
2
. For example “FOR=” compares S
1
and of S
2
,and if the
comparison result is “=”, the instruction is true, and if it is “
≠
”, the instruction is false.
2. The FOR* operands, can directly insert floating point numbers into S
1
and S
2
can each be 2 T,
C, D or actual floating point values (e.g. F1.2).
3. The FOR*instruction is an input instruction

Program Example:
If both X2 and M30 are “ON”, or if the contents of the floating point numbers D101, D100 are greater
or equal to F1.234, M60=ON.
FOR>= D100 F1.234
