PulseGenerator

Description

PulseGenerator class creates a pulse signal with a configurable pulse pause duration

Install this package

apax add @simatic-ax/generators

Namespace

Simatic.Ax.Generators;

Configuration

PulseTime	Defines the pulse time for the signal
PauseTime	Defines the pause time for the signal

Example configuration in a VAR section

 clock : PulseGenerator := (PulseTime := T#0.5s, PauseTime := T#0.5s);

Methods

Execute()	Execute the clock signal. Must called cycically
Q() : BOOL	Returns the clock signal
QRis() : BOOL	Returns the rising edge of the clock signal
QFal() : BOOL	Returns the falling edge of the clock signal

Example

USING Simatic.Ax.Generators;

CONFIGURATION MyConfiguration
    TASK Main(Priority := 1);
    
    PROGRAM P1 WITH Main: MainProgram;
        
    VAR_GLOBAL
        clock : PulseGenerator := (PulseTime := T#0.5s, PauseTime := T#0.5s);
        clk : BOOL;
    END_VAR
END_CONFIGURATION

PROGRAM MainProgram
    
    VAR_EXTERNAL
        clock : PulseGenerator;
        clk : BOOL;
    END_VAR

    clock.Execute();
    clk := clock.Q();
