HIEE410016P1脉冲输入卡件
如果从上一个样本到当前样本的工程单位变化为负值，则模块将比率变化与负值变化率参数进行比较。如果样本之间的工程单位变化为正值，则模块将比较速率变化与正值变化率参数值的结果。在任何一种情况下，如果变化率大于配置的变化率，则会发生变化率警报。模块在报警后采取的行动取决于已在“诊断报告启用”、“故障报告启用”和“中断启用”参数中设置的已启用变化率行动。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，模块将比较信道的每个输入样本的变化率。PACSystems*RX3i系统手册第12节GFK-2314T 2019年9月带HART通信505信道参数的模拟模块（续）参数默认值说明高-高报警（英制单位）高-高、高、低和低-低参数的默认值取决于配置的量程类型和量程。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指定。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，将触发低（高）报警。高报警死区和低报警死区：工程单位中高于报警条件（低死区）或低于报警条件（高死区）的范围，即使报警条件消失，报警状态位也可以保持设置。要清除报警状态，通道输入必须超出死区范围。报警死区不应导致报警清除条件超出工程单位用户限制范围。例如，如果通道的工程单位范围为-1000.0至+1000.0，且高报警设置为+100.00，则高报警死区值范围为0.0至小于1100.0。1100.0或更大的死区将使高报警清除条件低于–1000.0单位，从而使报警无法在限制范围内清除。高报警（Eng单位）低报警（Eng单位）低-低报警（Eng单位）高-高报警死区（Eng单元）高报警死区。该值在报警检查之前添加到通道上的缩放值。禁用/启用软件过滤。控制是否对输入执行软件过滤。积分时间（毫秒）0指定软件筛选器达到输入值63.2%的时间量（毫秒）。值为0表示软件过滤器已禁用。值为100表示数据将在100毫秒内达到其值的63.2%。默认值为0。PACSystems*RX3i系统手册第12节GFK-2314T 2019年9月带HART通信的模拟模块506 11.2.3.2.3使用报警：ALG626和ALG628诊断报告启用、故障报告启用、，
If the Engineering Units change from the previous sample to current sample is negative, the module compares the rate change with the Negative Rate of Change parameter. If the Engineering Units change between samples is positive, the module compares the results in comparing the rate change with the Positive Rate of Change parameter value. In either case, if the rate of change is greater than the configured rate, a rate of change alarm occurs. The actions taken by the module following the alarm depend on the enabled rate of change actions that have been set up in the "Diagnostic Reporting Enable", "Fault Reporting Enable", and "Interrupts Enabled" parameters. 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.

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. High and Low Alarm Deadbands: A range in Engineering Units above the alarm condition (low deadband) or below the alarm condition (high deadband) where the alarm status bit can remain set even after the alarm condition goes away. For the alarm status to clear, the channel input must fall outside the deadband range. Alarm Deadbands should not cause the alarm clear condition to be outside the Engineering Unit User Limits range. For example, if the engineering unit range for a channel is -1000.0 to +1000.0 and a High Alarm is set at +100.0, the High Alarm Deadband value range is 0.0 to less than 1100.0. A deadband of 1100.0 or more would put the High Alarm clear condition below –1000.0 units making the alarm impossible to clear within the limits. 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) Low-Low Alarm Deadband (Eng Units) User Offset 0.0 Engineering Units offset to change the base of the input channel. This value is added to the scaled value on the channel prior to alarm checking. Software Filtering Disabled Disabled / Enabled. Controls whether software filtering will be performed on the inputs. Integration Time (ms) 0 Specifies the amount of time in milliseconds for the software filter to reach 63.2% of the input value. A value of 0 indicates software filter is disabled. A value of 100 indicates data will achieve 63.2% of its value in 100ms. Default is 0.
