两组对应值之间的线性关系。它们不一定是输出的极限。PACSystems*RX3i系统手册第12节GFK-2314T 2019年9月模拟输出模块479示例在本示例中，应用程序应将32000计数解释为+10 Vdc，-32000计数解释为-10 Vdc。以下信道配置将将±10 Vdc输出信道缩放至±32000计数。信道值格式=16位整数高量程值（Eng单位）=32000.0低量程值（英制单位）=-3200.00高量程值，（A/D单位）=10.000低量程值，A/D单位）=10.000电压-10000+10000-32000计数32000图309：信道缩放示例PACSystems*RX3i系统手册第12节GFK-2314T 2019年9月模拟输出模块480信道参数（续）参数默认说明高报警（工程单位）默认值取决于配置的范围。所有报警参数均以工程单位指定。当达到或低于（高于）配置值时，将触发低（高）报警。低报警（工程单位）输出启用斜坡率（工程单位（Eng Units））0.0正常运行期间输出将发生变化的工程单位速率。默认斜坡速率（工程单位）0.0如果发生故障或未启用输出，输出将改变的工程单位速率。输出钳位启用禁用启用/禁用。请参阅以下说明。上限（英制单位）默认值取决于配置的量程。上限必须大于下限。此参数可用于将输出限制在比其配置的范围类型更窄的范围内。例如，为-10 Vdc至+10 Vdc配置的信道可能被限制为-8V至+7.5V。下限限值（英制单位）默认值（英制单元）0.0。如果禁用保持最后状态，则当CPU未处于输出启用模式或在特定故障条件下时，命令输出进入默认值。用户偏移（Eng Units）0.0可用于更改通道基础的可配置值。该值在报警检查之前添加到通道的缩放值。10.4.5.3下限、上限和警报警报可用于指示模块何时被指令达到或超过每个通道的配置上限或下限。这些设置在六个可配置报警触发点：▪ 高报警和低报警▪ 上夹具和下夹具▪ 超量程和欠量程报警每个报警可按通道单独配置，以生成诊断位状态、故障报警或中断报警。PACSystems*RX3i系统手册第12节GFK-2314T 2019年9月模拟输出模块481如果命令信道高于上限值，则输出设置为上限值，并指示上限条件。如果命令通道低于下限值，则输出设置为下限值，并指示下限条件。在可能通过斜坡、箝位和故障条件进行调整后，对工程单位输出值执行高报警和低报警检查。PACSystems*RX3i系统手册第12节GFK-2314T 2019年9月模拟输出模块482信道参数（续）参数默认说明诊断报告启用如果启用了诊断报告，下面列出的其他参数可用于启用特定类型的报警。Disabled Diagnostic Reporting Enable（禁用诊断报告启用）选项用于启用将报警报告到Diagnostic reference（诊断参考）区域的参考内存。故障报告启用选项可将报警记录到I/O故障表中。这些参数启用或禁用通道的各个诊断功能。当这些参数中的任何一个被启用时，模块使用相关参数来执行启用的功能。例如，如果在Diagnostic Reporting Enable（诊断报告启用）菜单中启用了Over Range（超出范围），则模块将在通道的Diagnostic Reference（诊断参考）中设置Over Range位。如果这些参数中的任何一个被禁用，则模块不会对相关报警条件做出反应。
linear relationship between two sets of corresponding values. They do not have to be the limits of the output. PACSystems* RX3i System Manual Section 12 GFK-2314T Sept. 2019 Analog Output Modules 479 Example In this example, the application should interpret 32000 counts as +10 Vdc and –32000 counts as -10 Vdc. The following channel configuration will scale a ±10 Vdc output channel to ±32000 counts. Channel Value Format = 16-bit Integer High Scale Value (Eng Units) = 32000.0 Low Scale Value (Eng Units) = -32000.0 High Scale Value (A/D Units) = 10.000 Low Scale Value (A/D Units) = -10.000 Voltage -10,000 +10,000 -32,000 Counts 32,000 Figure 309: Channel Scaling Example PACSystems* RX3i System Manual Section 12 GFK-2314T Sept. 2019 Analog Output Modules 480 Channel Parameters (Continued) Parameter Default Description High Alarm (Eng Units) The defaults depend on the configured Range. All of the alarm parameters are specified in Engineering Units. When the configured value is reached or below (above), a Low (High) Alarm is triggered. Low Alarm (Eng Units) Outputs Enabled Ramp Rate (Eng Units) 0.0 The rate in Engineering Units at which the output will change during normal operation. Default Ramp Rate (Eng Units) 0.0 The rate in Engineering Units at which the output will change if a fault condition occurs or if outputs are not enabled. Output Clamping Enabled Disabled Enabled / Disabled. Refer to description below. Upper Clamp Limit (Eng Units) The defaults depend on the configured Range. The Upper Clamp Limit must be greater than the Lower Clamp Limit. This parameter can be used to restrict the output to a range that is narrower than its configured Range Type. For example, a channel configured for –10 Vdc to +10 Vdc could be restricted to -8V to +7.5V. Lower Clamp Limit (Eng Units) Default Value (Eng Units) 0.0 If Hold Last State is disabled, the output is commanded to go to the Default Vale when the CPU is not in Outputs Enabled mode or under certain fault conditions. User Offset (Eng Units) 0.0 A configurable value that can be used to change the base of the channel. This value is added to the scaled value of the channel before alarm-checking. 10.4.5.3 Lower, Upper Clamp and Alarms Alarms can be used to indicate when the module has been commanded to meet or exceed the configured high or low limits for each channel. These are set at six configurable alarm trigger points: ▪ High Alarm and Low Alarm ▪ Upper Clamp and Lower Clamp ▪ Over-range and Under-range Alarm Each alarm is individually configurable per channel to generate diagnostics bit status, fault alarms, or interrupt alarms. PACSystems* RX3i System Manual Section 12 GFK-2314T Sept. 2019 Analog Output Modules 481 If a channel is commanded higher than the Upper Clamp value, the output is set to the Upper Clamp value and an Upper Clamp condition is indicated. If a channel is commanded lower than the Lower Clamp value, the output is set to the Lower Clamp value and a Lower Clamp condition is indicated. The High and Low Alarm checks are performed on the engineering units output value after possibly being adjusted by ramping, clamping, and fault conditions. PACSystems* RX3i System Manual Section 12 GFK-2314T Sept. 2019 Analog Output Modules 482 Channel Parameters (Continued) Parameter Default Description Diagnostic Reporting Enable If Diagnostic Reporting is enabled, the additional parameters listed below can be used to enable specific types of alarms. Disabled Diagnostic Reporting Enable options are used to enable reference memory reporting of alarms into the Diagnostic Reference area. Fault Reporting Enable options enable fault logging of alarms into the I/O Fault Table. These parameters enable or disable the individual diagnostics features of a channel. When any of these parameters is enabled, the module uses associated parameters to perform the enabled feature. For example, if Over Range is enabled in the Diagnostic Reporting Enable menu, the module will set the Over Range bit in the Diagnostic Reference for the channel. If any of these parameters is disabled, the module does not react to the associated alarm conditions.
