Calculate Sine
S : the source device for input the angle in radians
D : the calculated result
This instruction performs the mathematical sine operation on the designated BIN oating point radians of
angle, and the result is stored in the designated device.
When X0 = “ON”, the instruction is activated, it uses the BIN oating point radians at (D1, D0) to calculate the sine
value, and the result will be stored at the specied destination devices (D11, D10).
Radian = Degree × π / 180
This instruction is a 32-bit instruction. Therefore, be sure to input DSIN or DSINP in the program.
The source operand must assign to a BIN oating point number for the calculation, and the calculated result
is by the BIN oating point format, too.
The format for storing a oating point number will occupy two Registers in the PLC system. Please refer to the
section 2-13 “Numerical System” for the reference of the oating point number.
The example below is to calculate the 45 degree angle become a radian value of oating point, then use the
radians to get the result value of SIN.
The angel of 45 degree×( π / 180 ) → (D3, D2) [Unit: radian]
The result value of SIN is stored in (D11, D10).
