MVME172-223

变化率采样率参数确定模块比较变化率的频率。如果变化率采样率为0或小于信道更新率的任何时间段，模块比较通道每个输入样本的变化率。高-高报警（Eng单位）高报警（Eng单位）低报警（Eng单位）低-低报警（Eng单位）高-高警报死区（Eng单元）高-警报死区（Eng单元）低警报死区（Eng单位）高-高、高、低和低-低参数的默认值取决于配置的范围类型和范围。每个范围和范围类型都有一组不同的默认值。报警和死区所有报警参数均在工程单位中***。要使用报警，A/D报警模式也必须配置为启用。高-高报警和低-低报警：当达到或通过配置值时，将触发低-低警报或高-高警报。配置值必须低于/高于相应的低/高报警限值。高报警和低报警：当达到或低于（高于）配置值时，会触发低（高）报警。

The Rate of Change Sampling Rate parameter determines how frequently the module compares the Rate of Change. If the Rate of Change Sampling Rate is 0 or any time period less than the channel update rate, the module compares the Rate of Change for every input sample of the channel.High-High Alarm (Eng Units) High Alarm (Eng Units) Low Alarm (Eng Units) Low-Low Alarm (Eng Units) High-High Alarm Deadband (Eng Units) High Alarm Deadband (Eng Units) Low Alarm Deadband (Eng Units) The defaults for the High-High, High, Low, and Low-Low parameters depend on the configured Range Type and Range. Each Range and Range Type has a different set of default values. Alarms and Deadbands All of the alarm parameters are specified in Engineering Units. To use alarming, the A/D Alarm Mode must also be configured as enabled. High-High Alarm and Low-Low Alarm: When the configured value is reached or passed, a Low-Low Alarm or High-High Alarm is triggered. The configured values must be lower than/higher than the corresponding low/high alarm limits. High Alarm and Low Alarm: When the configured value is reached or below (above), a Low (High) Alarm is triggered.
