Operands:
Please refer to the specifications of each model for the
range of operands.
 S: Source device (0°≦S＜360°) D: Operation result
Explanation
The value in S can be set as radian or degree by flag M1018.

 M1018 = OFF, radian mode. RAD = degree ×π/180.
 M1018 = ON, degree mode. Degree range: 0°≦degree＜360°.
 When the operation result = 0, M1020 = On.
 TAN instruction performs tangent operation on S and stores the result in D.
See the figure below for the relation between the radian and the operation result
-2
When X0 = ON, DTAN instruction performs tangent operation on the radian value in (D1,
Example
D0) and stores the TAN value in (D11, D10) in binary floating format
