456▪ 如果电源的背板电源丢失，则忽略默认斜坡速率配置。为“默认值”配置的通道立即变为默认值。▪ 背板电源恢复后首次存储配置时，不使用默认斜坡速率。为“默认值”配置的任何通道都会立即变为其默认值。如果模拟电源未丢失，并且在下一次通电时恢复了相同的配置，则信道状态自断电时起保持不变。默认斜坡速率用于任何后续重新配置。PACSystems*RX3i系统手册第12节GFK-2314T 2019年9月模拟输出模块457输出默认条件和动作条件保持最后状态或默认值默认斜坡率启用输出启用和斜坡率启用信道输出设置（除非另有说明，否则假设存在场功率）。输出启用和无故障N/A N/A无输出从参考存储器转到其命令值；默认值不适用。N/A N/A是输出以输出启用斜坡速率斜坡至参考存储器的命令输出。默认值不适用。输出禁用、故障模式或重新配置默认值否N/A输出设置为默认值默认值是N/A输出以默认斜坡速率斜坡至默认值，从进入模式前的最后一个命令值开始。保持最后状态N/A N/A输出保持在上电默认值N/A N/A输出设置为默认值后的最后命令值Loss of Backplane Power或First Configuration Store。保持最后状态N/A N/A输出保持在最后命令值。热移除、SVCREQ 24复位或清除配置N/A N/A N/A输出保持在最后命令值。失去磁场电源不适用不适用所有输出均为0V和0mA。PACSystems*RX3i系统手册第12节GFK-2314T 2019年9月模拟输出模块458 10.3.13.2信道参数参数默认说明高标度值（英制单位）四个标度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。注：如果高量程工程单位等于高量程A/D单位，而低量程工程单位则等于低量程A/D单位时，则禁用缩放。默认值=所选范围类型的A/D上限。低量程值（工程单位）默认值为所选量程类型的低A/D限值。必须低于高缩放值。高比例值（A/D单位）默认值为所选范围类型的高A/D限制。必须大于低缩放值。低量程值（A/D单位）默认值为所选量程类型的低A/D限值。10.3.13.2.1输出缩放：ALG704和ALG708默认情况下，
456 ▪ Default Ramp Rate configuration is ignored if backplane power from the power supply is lost. Channels configured for Default Value go to the default value immediately. ▪ The first time a configuration is stored following a return of backplane power, the Default Ramp rate is not used. Any channel configured for Default Value goes to its default value immediately. If analog power was not lost and the same configuration is restored on the next power-up, the channel state is unchanged from the time the power was lost. The Default Ramp Rate is used for any subsequent reconfiguration.

Each Range and Range Type have a different set of defaults. Note: Scaling is disabled if both High Scale Eng. Units equals High Scale A/D Units and Low Scale Eng. Units equals Low Scale A/D Units. Default = High A/D Limit of selected range type. Low Scale Value (Eng Units) Default is Low A/D Limit of selected range type. Must be lower than the high scaling value. High Scale Value (A/D Units) Default is High A/D Limit of selected range type. Must be greater than the low scaling value. Low Scale Value (A/D Units) Default is Low A/D Limit of selected range type. 10.3.13.2.1 Output Scaling: ALG704 and ALG708 By default,
