FP_SINH

Hyperbolic sine

This FP instruction calculates the hyperbolic sine of the angle data specified by input variable s. The result is stored in d.

Parameters

Input

s (ANY_REAL): Hyperbolic angle

Output

d (ANY_REAL): Hyperbolic sine of input value

Error flags

sys_bIsOperationErrorHold (turns to TRUE and remains TRUE)

if the area specified using the index modifier exceeds the limit.
if a data type other than REAL is specified.

sys_bIsOperationErrorNonHold (turns to TRUE for one scan)

if the area specified using the index modifier exceeds the limit.
if a data type other than REAL is specified.

Example

POU header

All input and output variables used for programming this function have been declared in the POU header. The same POU header is used for all programming languages.

	VAR
		bStart: BOOL:=FALSE;
			(*activates the instruction*)
		rInputValue: REAL:=0.0;
			(*angle data in radians*)
		rOutputValue: REAL:=0.0;
			(*result*)
	END_VAR

This example uses variables. You can also use a constant for the input variable.

LD body

When the variable bStart is set to TRUE, the function is carried out. The sine of rInputValue is calculated and written into rOutputValue.
