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

TAN

Function Name	TAN
Description	Converts a REAL or LREAL input into a tangent value that is the output. The tangent 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

TAN

Description

Converts a REAL or LREAL input into a tangent value that is the output. The tangent 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 - TAN:

In this example, the input of 5 is provided by the CurrentValueFormatted property of a point. The TAN function converts the value into a tangent value of -3.38051500624659.

ST Program - TAN:

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

Output := TAN (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).
