8 APPLICATION INSTRUCTION
8.9 Real Number Instruction
Processing details
• These instructions calculate the angle from the sine of the angle specified by (s), and store the operation result in the
device specified by (d).
• The sine value specified by (s) can be set ranging from -1.0 to 1.0.
• The angle (operation result) stored in (d) is expressed in radians (from (-
/2) to (
/2)).
• The table below shows the related devices.
Operation error
For the radian
angle conversion, refer to the DRAD(P) and DDEG(P) instructions.
