FB_ALY_SignalGenerator_1Ch

Signal Generator 1Ch can be used to generate various signal curves. The signal type, the frequency, the amplitude and the offset can be set individually.

Syntax

Definition:

FUNCTION_BLOCK FB_ALY_SignalGenerator_1Ch
VAR_OUTPUT
    ipResultMessage: Tc3_EventLogger.I_TcMessage;
    bError: BOOL;
    bNewResult: BOOL;
    bConfigured: BOOL;
    fSignal: 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.
fSignal	LREAL	Output of the configured signal

Methods

Name	Definition location	Description
Call()	Local	Method for calculating the outputs for a specific configuration.
Configure()	Local	General configuration of the algorithm with its parameterized conditions.
Reset()	Local	Resets all internal states or the calculations performed so far.

Sample

VAR
    fbSignalGenerator : FB_ALY_SignalGenerator_1Ch;
    eFunctionType : E_ALY_FunctionType := E_ALY_FunctionType.Sine;
    fSampleRate : LREAL := 1000.0;
    fFrequency : LREAL := 50.0;
    fAmplitude : LREAL := 100.0;
    fOffset : LREAL := 0.0;
    bConfigure : BOOL := TRUE;
END_VAR

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

    fbSignalGenerator.Configure(eFunctionType, fSampleRate, fFrequency, fAmplitude, fOffset);
END_IF

// Call algorithm
fbSignalGenerator.Call();
