Special Function Instructions

• Basic model QCPU: The serial number (first five digits) is "04122" or later.

(S): Angle data of which the SIN (sine) value is obtained or head number of the devices where the angle data is stored (real number)

(D): Head number of the devices where the operation result will be stored (real number)

Internal device

*1 Applicable for the Universal model QCPU, LCPU.

Processing details

• Returns the SIN (sine) value of the angle designated at (S) and stores the operation result in the device number designated

32-bit floating-point

• Angles designated at (S) are set in radian units (degrees   / 180). For conversion between degrees and radian values,

see the RAD and DEG instructions.

• When an input value is set using a programming tool, a rounding error may occur. For precautions, refer to Page 89

Precautions.

Operation error

• In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and an error code is stored into SD0.

Error details

The specified device value is -0.

An error occurred during the operation.

The specified device value is -0, unnormalized number, nonnumeric, and .

The operation result exceeds the following range.

(when an overflow occurs)

|Operation result| < 2

An error occurred during operation.

*2 There are CPU modules that will not result in an operation error if -0 is specified. For details, refer to Page 87 Using single/double-

precision real number data.
