Hello,
I was using a specific period such as 26 s for example, how can I do?Thank you
Kind Regards,
David

@Configurable("Period Premier ")
public Period PeriodPremierTick = Period.TEN_SECS;

Try:

    @Configurable("")
    public Unit periodUnit = Unit.Second;
    @Configurable("")
    public int periodUnitCount = 12;
    
    @Override
    public void onStart(IContext context) throws JFException {
        Period customPeriod = Period.createCustomPeriod(periodUnit, periodUnitCount);
    }
