Operands:
S: Source device (binary floating value) D: Operation result
Explanations:
1. ASIN instruction performs arc sine operation on S and stores the result in D
2. ASIN value = SIN
-1
3. See the figure below for the relation between input S and the result:
R
S

-
0
1,0-1,0
S: Input (SIN value)
R: Result (ASIN value)
4. If operation result in D is 0, Zero flag M1020 = ON.
5. The decimal value of the SIN value designated by S should be within -1.0 ~ +1.0. If the value
exceeds the range, M1067 and M1068 will be ON and instruction will be disabled.
Program Example:
When X0 = ON, DASIN instruction performs arc sine operation on the binary floating value in (D1,
D0) and stores the ASIN value in (D11, D10) in binary floating format..
