    snippet:

        // Statistic in IEC of the EtherCAT master  
    Ethercat_master_SoftMotion.GetStatistics(udiSendFrameCount => udiEthSendCount, udiFramesPerSecond => udiEthSendFramesPerSec, 
    udiLostFrameCount => udiEthLostFrameCount, udiTxErrorCount => udiEthTxErrCount, udiRxErrorCount => udiEthRxErrCount);

    // The statistics can be cleared via button
    IF _xResetEthStatistics THEN 
        Ethercat_master_SoftMotion.ClearStatistics();

        _pdiResetMax := ADR(EtherCAT_Master_SoftMotion.m_Master.m_diMaxSyncTime);
        _pdiResetMin := ADR(EtherCAT_Master_SoftMotion.m_Master.m_diMinSyncTime);
        _pdiResetMax^ := 0;
        _pdiResetMin^ := 0;             // why not 16#7FFFFFF??
        _diAbsMaxSyncTime := 0;
        _diAbsMinSyncTime := 16#7FFFFFF;
        dwEthSendFrameMax := 0;
        dwEthGetFrameMax := 0;

        _xResetEthStatistics := FALSE;
    END_IF
