Operands:

S: Source device (0°≦S＜360°) D: Operation result

Explanations:

1.TAN instruction performs tangent operation on S and stores the result in D.

2.The value in S can be set as radian or degree by flag M1018.

3.M1018 = OFF, radian mode. RAD = degree ×π/180.

4.M1018 = ON, degree mode. Degree range: 0°≦degree＜360°.

5.Flag: M1018 (Flag for Radian/Degree)

6.See the figure below for the relation between the radian and the operation result

R

S: Radian

R: Result (TAN value)

7.If operation result in D is 0, Zero flag M1020 = ON.

Program Example 1:

M1018 = OFF, radian mode. When X0 = ON, DTAN instruction performs tangent operation on the radian value in (D1, D0) and stores the TAN value in (D11, D10) in binary floating format.
