Logic Guide - SIN (Built-in Functions, Function Blocks, and Conversions)

SIN

Function Name	SIN
Description	Converts a REAL or LREAL input into a sine value that is the output. The sine value is also a REAL or LREAL.
Arguments	Input 1 {REAL or LREAL}. This value is in radians. For more information on the data types for the inputs and outputs, see Data Type Hierarchy.
Returns	Output {REAL or LREAL}.

Function Name

SIN

Description

Converts a REAL or LREAL input into a sine value that is the output. The sine value is also a REAL or LREAL.

Arguments

Input 1 {REAL or LREAL}. This value is in radians.

For more information on the data types for the inputs and outputs, see Data Type Hierarchy.

Returns

Output {REAL or LREAL}.

Example:

Function Block Diagram - SIN:

In this example, the input of 5 is provided by the CurrentValueFormatted property of a point. The SIN function converts the value into a sine value of -0.958924274663138 and this is used as the output.

ST Program - SIN:

The syntax for a SIN function in an ST Program is:

Output := SIN (Input 1);

Where Output and Input 1 are defined as variables earlier in the ST program. The Input 1 variable represents a REAL or LREAL type of value (the output is the same type of value as Input 1).
