Operands
| Operand | Description |
|---|---|
| S | The first operand. Entries are REAL data registers or constants. This is the value to calculate the sine value of. The value range is -1.7014118e+38 ~ 3.4028237e+38 (2-127 ~ 2128). |
| D | The second operand. Entries are only REAL data registers. The sine is saved as a REAL data register in radians. |

Notice
Error Flag (F11.0) Notice
The error flag, F11.0, will be ON for one scan when the address of the data register assigned by @D exceeds the range of the data register, D. The range of the data register, D, is dependent on the CPU type. F11.0 turns ON when the value of the data for the calculation exceeds the data register assigned to S or D. When the value assigned to S exceeds its range, the value, Quite Not-a-Number (-1.#QNAN0), is stored in the data register D.
Instruction Result
The value resulting from the SIN or SINP instruction is saved as a radian. The conversion for radians is: Radians = Degrees × ( π⁄180 )
Ladder Diagram Examples
SIN
The SIN instruction calculates the sine of the REAL operand, S, and saves the result in an assigned REAL data register, D.
When the contact, M0.0, is ON (1), the instruction executes sin(1.5) and saves the result, 0.997495.
Memory Monitor
SINP
The SINP one-shot instruction calculates the sine of the REAL operand, S, and saves the result in an assigned REAL data register, D. Every time this instruction executes, it energizes the output only once.
When the contact, M0.1, is ON (1), the instruction executes sin(1.56) and saves the result, 0.999942.
