事件后的情況不太重要，尤其是在記錄模式B中，在這種情況下，簡單地延長記錄的持續時間。重要的是，在事后記錄時，新的觸發信號可以啟動新的事件。然而，這意味著兩個事件重疊
并非總是能夠完全重建以下情況：兩個事件（部分事件前數據在前一事件中）。
整個事件存儲器作為環形寄存器運行。這意味著可以刪除單個事件，以便為新事件騰出空間而不必刪除其他。可以選擇內存已滿時遵循的步驟。記錄中斷，并且沒有新事件發生記錄或最舊的記錄被重寫，以便內存始終包含最新的事件。必須注意的是在該模式下，記錄可以在傳輸到操作員站之前刪除。即使記錄的傳輸正在進行進程將被中斷，以便為新記錄騰出空間。應用程序干擾記錄器數據、電流、電壓和測量值函數變量可以傳遞回RE。216裝置使用轉換程序接口和測試集XS92a（參見接口操作說明CH-ES 86-11.53 E）。
有關通過IBB傳輸干擾數據的程序
，請參閱第9.3節。干擾記錄器數據文件以二進制格式存儲，并且只能使用WinEVE程序進行評估（參見WinEVE操作說明*BHT 450 045 D0000）或修訂程序
（見第1MDU10024-EN版操作說明）。
測量的函數變量可能有值，但不能完全由評估軟件復制。此類變量可以使用比例因子“MeasCale”來減少。這個評估軟件可以忠實再現的最高數字為±16535。評估軟件自動考慮比例因子。處理器容量：干擾記錄器功能在同一中央控制系統上運行作為保護功能的處理單元（CPU）。處理器
干擾記錄器功能所需的容量占總容量的百分比，并與信號為：
9個模擬信號和0個二進制信號的20%9個模擬信號和16個二進制信號的40%
The post-event circumstances are of less importance, especially
in recording mode B, in which case simply the duration of recording is extended. The essential thing is that during post-event
recording, a new trigger signal can initiate the recording of new
events. This, however, means that two events overlap and it may
not always be possible to fully reconstruct the circumstances of
both events (part of the pre-event data is in the preceding event).
The entire event memory operates as a ring register. This means
that a single event can be deleted to make room for a new one
without having to delete the others.
The procedure followed when the memory is full can be selected. Either recording is discontinued and no new events are
recorded, or the oldest records are overwritten so that the memory always contains the latest events. It must be noted that in
this mode, a record can be deleted before it has been transferred to an operator station. Even if transfer of a record is in
progress, it will be interrupted to make room for a new record.
Application programs
Disturbance recorder data, currents, voltages and measured
function variables can be transferred back to the RE. 216 device
using the conversion program INTERFAC and test set XS92a
(see INTERFAC Operating Instructions CH-ES 86-11.53 E).
Refer to Section 9.3 for the procedure for transferring disturbance data via the IBB.
Disturbance recorder data files are stored in a binary format and
can only be evaluated using the WinEVE program (see WinEVE
Operating Instructions *BHT 450 045 D0000) or REVAL program
(see REVAL Operating Instructions 1MDU10024-EN).
Measured function variables may have values which cannot be
entirely reproduced by the evaluation software. Such variables
can be reduced using the scaling factors ‘MeasScale’. The
highest number the evaluation software can reproduce faithfully
is ±16535. The evaluation software automatically takes account
of the scaling factors.Processor capacity:
The disturbance recorder function runs on the same central
processing unit (CPU) as the protection functions. The processor
capacity required by the disturbance recorder function as a percentage of the total capacity and in relation to the number of
signals is:
20% for 9 analogue and 0 binary signals
40% for 9 analogue and 16 binary signals
