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, “FAND=”,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 FAND* 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 FAND* instruction is an input instruction
API No.
