| Sample and Hold [v] （采樣保持） | False | Flag 此標(biāo)簽(True/False)用于指示DV是否不常采樣（即它是一個采樣保持裝置如氣相色譜儀）。 |
| Measured Disturbance Filter [t/v]（測量干擾濾波器） | 0 | 如果需要可將DV測量值進行過濾。此參數(shù)設(shè)置了DV測量值一階指數(shù)濾波器的時間常數(shù)（s）滤愕。 |
| Minimum Value [v] （最小值） | -10000.0 | 這是DV測量值所允許的最小值鸟召，否則測量將被申明為無效（內(nèi)部DV將被斷開，SMOCPro將使用內(nèi)部預(yù)測）了牛。 |
| Maximum Value [v] （最大值） | 10000.0 | 這是DV測量值所允許的最大值颜屠，否則測量將被申明為無效（內(nèi)部DV將被斷開辰妙，SMOCPro將使用內(nèi)部預(yù)測）。 |
| Minimum Deviation [v] （最小偏差） | 0.0 | 這是控制器執(zhí)行時工程單位上DV測量值最小必須改變量甫窟，否則測量值將被申明為無效（內(nèi)部DV將斷開且SMOCPro將使用內(nèi)部預(yù)測）密浑。 |
| Maximum Deviation [v] （最大偏差） | 10000.0 | 這是控制器執(zhí)行時工程單位上DV測量值所允許改變的最大量，否則測量值將被申明為無效（內(nèi)部DV將斷開且SMOCPro將使用內(nèi)部預(yù)測）粗井。 |
| Actual DV Status [t/v] （DV實際狀態(tài)） | INACTIVE | DV (內(nèi)核輸出參數(shù))的實際狀態(tài)(BAD/ ACTIVE/INACTIVE)尔破。只有選中Advanced 時才可見。 |
| Max Time for Rejected Value [v]（拒絕值的最大時間） | 0.0 | 從值被DV Check（數(shù)據(jù)直接到內(nèi)核）所拒絕開始至DV實際狀態(tài)變?yōu)镮NACTIVE的最大時間（s）浇衬。只有選中Advanced該值才可見懒构。當(dāng)QMI 測量值的采樣周期比控制器執(zhí)行周期更長時，如果最小值非零則在樣本之間DV狀態(tài)將變?yōu)镮NACTIVE耘擂。這會導(dǎo)致在每個采樣后產(chǎn)生"Invalid DV Measurement（無效DV測量量）"的錯誤信息胆剧。若要取消錯誤信息，則Max Time for Rejected Value 設(shè)定值必須大于QMI 采樣時間值醉冤。 Max Time Invalid （最大無效時間）設(shè)定值必須大于Max Time for Rejected Value（拒絕值最大時間）,否則錯誤信息將不能正確抑制秩霍。 如果DV Check拒絕了輸入的測量值， 不管Max Time for Rejected Value 的值是多少蚁阳，其都將不會更新內(nèi)部預(yù)測铃绒。 |
原文：
| Sample and Hold [v] | False | Flag (True/False) to indicate if this DV is sampled infrequently (that is, it is a sample-and-hold device such as e.g. a Gas Chromatograph). |
| Measured Disturbance Filter [t/v] | 0 | The DV measurement may be filtered if desired. This parameter sets the time constant (in seconds) of a first-order exponential filter of the DV measurement. |
| Minimum Value [v] | -10000.0 | This is the minimum value allowed for the DV measurement, otherwise the measurement is declared to be Invalid (internally the DV will be disconnected and SMOCPro will use internal prediction). |
| Maximum Value [v] | 10000.0 | This is the maximum value allowed for the DV measurement, otherwise the measurement is declared to be Invalid (internally the DV will be disconnected and SMOCPro will use internal prediction). |
| Minimum Deviation [v] | 0.0 | This is the minimum amount in engineering units that the DV measurement must change per execution of the controller, otherwise the measurement is declared to be Invalid (internally the DV will be disconnected and SMOCPro will use internal prediction). |
| Maximum Deviation [v] | 10000.0 | This is the maximum amount in engineering units that the DV measurement is allowed to change per execution of the controller, otherwise the measurement is declared to be Invalid (internally the DV will be disconnected and SMOCPro will use internal prediction). |
| Actual DV Status [t/v] | INACTIVE | The actual status (BAD/ACTIVE/INACTIVE) of DV (Kernel output parameter). Visible only when Advanced option is selected. |
| Max Time for Rejected Value [v] | 0.0 | Maximum time in seconds before the DV’s actual status becomes INACTIVE when the value is rejected by DV Check (Data to Kernel directly). This quality is visible only when the Advanced option is selected.When the QMI measurement has a longer sample time than the controller execution period, DV status will be INACTIVE between samples if Minimum Value is non-zero. This causes the following error message "Invalid DV Measurement" to be generated after every sample. To suppress the error message, Max Time for Rejected Value should be set to a value slightly greater than the QMI sample time. Max Time Invalid must be set to a value greater than Max Time for Rejected Value, otherwise the error message will not be suppressed properly. If DV Check rejects the incoming Measurement, it will not be used to update the internal prediction regardless of the value for Max Time for Rejected Value. |
