全局变量法

/*@!Encoding:936*/
includes
{

{
  byte Counter_SendFrame_GW_2F4_CdcEcasMaintenanceModeReq = 0;

      }    
  }
}

不需要全局变量法

/*@!Encoding:936*/
includes
{
  
}

variables
{

}

//三帧触发逻辑
on signal_update CdcEcasMaintenanceModeReq
{
  int i;
  if(@sysvar::SignalTiming::ARun::`Start ==1)
  { 
    if(getSignal(CdcEcasMaintenanceModeReq)!= DBLookup(CdcEcasMaintenanceModeReq).DefaultValue)
    {
      i++;
      if(i==3)
      {
        setsignal(CdcEcasMaintenanceModeReq,DBLookup(CdcEcasMaintenanceModeReq).DefaultValue);
        i = 0;
      }
    }
  }
}
