如果模擬電源未丟失，并且在下一次通電時恢復了相同的配置，則信道狀態自斷電時起保持不變。默認斜坡速率用于任何后續重新配置。PACSystems*RX3i系統手冊第12節GFK-2314T 2019年9月模擬輸出模塊477輸出默認條件和動作條件保持最后狀態或默認值默認斜坡率啟用輸出啟用和斜坡率啟用信道輸出設置（除非另有說明，否則假設存在場功率）。輸出啟用和無故障N/A N/A無輸出從參考存儲器轉到其命令值；默認值不適用。N/A N/A是輸出以輸出啟用斜坡速率斜坡至參考存儲器的命令輸出。默認值不適用。輸出禁用、故障模式或重新配置默認值否N/A輸出設置為默認值默認值是N/A輸出以默認斜坡速率斜坡至默認值，從進入模式前的最后一個命令值開始。保持最后狀態N/A N/A輸出保持在上電后背板功率損失或第一配置存儲的最后命令值，范圍類型具有不同的默認設置。注：如果高量程工程單位等于高量程A/D單位，而低量程工程單位則等于低量程A/D單位時，則禁用縮放。默認值=所選范圍類型的A/D上限。低量程值（工程單位）默認值為所選量程類型的低A/D限值。必須低于高縮放值。高比例值（A/D單位）默認值為所選范圍類型的高A/D限制。必須大于低縮放值。低量程值（A/D單位）默認值為所選量程類型的低A/D限值。10.4.5.2.1輸出縮放默認情況下，模塊將CPU的浮點值轉換為其配置范圍的整個范圍內的電壓或電流輸出。例如，如果信道的范圍為4至20mA，則模塊接受4.000至20.000的信道輸出值。通過修改四個信道縮放參數（低/高縮放值參數）中的一個或多個，可以針對特定應用更改縮放工程單位范圍。縮放始終是線性的，可以進行逆縮放。所有報警值都適用于縮放的工程單位值，而不是A/D單位值。縮放參數僅設置
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.

Outputs Enabled and No Faults N/A N/A No Output goes to its commanded value from reference memory; defaults don’t apply. N/A N/A Yes Output is ramped to the commanded output from reference memory at the Outputs Enabled ramp rate. Defaults don’t apply. Outputs Disabled, Fault Mode, or Reconfiguration Default Value No N/A Output is set to the Default Value Default Value Yes N/A Output is ramped to the Default Value at the Default ramp rate, starting at the last commanded value before entering mode.

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. 10.4.5.2.1 Output Scaling By default, the module converts a floating-point value from the CPU into a voltage or current output over the entire span of its configured Range. For example, if the Range of a channel is 4 to 20mA, the module accepts channel output values from 4.000 to 20.000. By modifying one or more of the four channel scaling parameters (Low/High Scale Value parameters) from their defaults, the scaled Engineering Unit range can be changed for a specific application. Scaling is always linear and inverse scaling is possible. All alarm values apply to the scaled Engineering Units value, not to the A/D units value. The scaling parameters only set up the
