FB_ALY_MathOperation_1Ch

The Math Operation 1Ch executes a mathematical operation on the signal of the input channel and a reference value. The algorithm provides the result of the mathematical operation and the operator can be configured individually.

Syntax

Definition:

FUNCTION_BLOCK FB_ALY_MathOperation_1Ch
VAR_OUTPUT
    ipResultMessage: Tc3_EventLogger.I_TcMessage;
    bError: BOOL;
    bNewResult: BOOL;
    bConfigured: BOOL;
    fResult: LREAL;
END_VAR

Outputs

Name	Type	Description
ipResultMessage	I_TcMessage	Contains more detailed information on the current return value. This special interface pointer is internally secured so that it is always valid/assigned.
bError	BOOL	This output is `TRUE` if an error occurs.
bNewResult	BOOL	When a new result has been calculated, the output is `TRUE.`
bConfigured	BOOL	Displays `TRUE` when the function block is successfully configured.
fResult	LREAL	Outputs the result of the mathematical operation.

Methods

Name	Definition Location	Description
Call()	Local	Method calculates the outputs for a given configuration.
Configure()	Local	General configuration of the algorithm with its parameterized conditions.
Reset()	Local	Resets all internal states or the calculations made so far.
SetChannelValue()	Local	Method to pass values to the algorithm.

Sample

VAR
    fbMathOperation : FB_ALY_MathOperation_1Ch;
    fOperand : LREAL := 50;
    eMathOperator : E_ALY_MathOperator := E_ALY_MathOperator.Addition;
    bUseAbsValues : BOOL := FALSE;
    bConfigure : BOOL := TRUE;
    nInput : INT;
END_VAR

// Configure algorithm
IF bConfigure THEN
    bConfigure := FALSE;

    fbMathOperation.Configure(fOperand, eMathOperator, bUseAbsValues);
END_IF

// Call algorithm
fbMathOperation.SetChannelValue(nInput);
fbMathOperation.Call();
