采集周期
使用“Period（周期）”或“No. of Sample(样本数) ”指定数据采集周期。如上所述当选中“Future Value（未来值）”时，该选项有效。
Period（周期）将指定采集周期的量，时间单位为小时/分钟/秒。这是一个正数。No. of Sample(样本数)将采集周期指定为下面描述的“Acquisition Cycle（采集周期）”的倍数。它也是一个正数。
开始时间/结束时间
指定数据采集的开始时间和结束时间。当选中“Past Value（历史值）”时，该选项有效。数据格式为“MM / DD / YYYY HH：MM：SS”。
结束时间的默认值为“Now”。
采集周期
指定数据采集周期。每个采集周期通过OPC服务器从DCS收集数据。
数据
Start（开始）和Terminate（终止）按钮用于启动和停止数据采集。通过单击“Start（开始）”按钮，工具将检查输入数据。如果没有任何错误，数据采集将启动，并通过OPC DA服务器或HDA服务器收集数据。
消息“Collecting Data ….”将显示在窗口底部。
单击“Terminate（终止）”按钮，将显示对话框消息，以确认停止操作。当选择yes时，数据采集将中途停止，收集的数据和信息保存在指定的文件夹中。此按钮仅在选择“Future Value（未来值）”模式并单击“Start”按钮后有效。
数据收集完成后，将显示以下对话框。 并将统计显示“Bad”或“Questionable”数据的数量。收集的数据存储在指定的“Data File”文件中。
Data Archiving Tool（数据归档工具）窗口右侧的Data grid（数据网格）将显示“Future Value（未来值）”时收集的数据。每个收集的数据包含显示的ItemID，最近获取的时间，数据值和质量标志（Good, Bad或Questionable）。

显示数据
单击“Time Series（时间序列）”下拉菜单中的“Display Data（显示数据）”或双击数据网格的网格，获取的数据将显示在“Time Series（时间序列）”窗口中。最多同时显示三个窗口。 如果数据样本数大于30，则可用滚动条。
通过双击已显示的数据行，也可显示“Time Series（时间序列）”窗口。

Acquisition Period
Specify the data acquisition period using “Period” or No. of Sample”. This selection is effective when “Future Value” is selected described above.
Period specifies the acquisition period as the number of time units hour / minute / second. It is a positive number. No. of samples specifies the acquisition period as the multiple number of “Acquisition Cycle” described below. It is also a positive number.
Start Time / End Time
Specify the starting time and ending time for data acquisition. This selection is effective when “Past Value” is selected described above. Data format is ”MM/DD/YYYY HH:MM:SS”.
The default value of End Time is “Now”.
Acquisition Cycle
Specify the data acquisition cycle. Data is collected from DCS via OPC server every acquisition cycle.
Data
Start and Terminate buttons is used to start and stop the data acquisition. By clicking the “Start” button, the tool checks the input data. If there is not any error, the data acquisition starts and data is collected via OPC DA server or HDA server.
Message “Collecting Data …” is displayed on the bottom of the window.
By clicking “Terminate” button, the dialog message is displayed for confirmation of the stop operation. When selected yes, the data acquisition stops on the way and the collected data and information are saved on the specified folder. This button is only effective on “Future Value” mode is selected and after “Start” button is clicked.
When the data collection finished, the following dialog is displayed. Number of “Bad” or ”Questionable” data are counted and displayed. Collected data is stored on the file specified “Data File”.
Data grid on the right side of the Data Archiving Tool window shows the collected data in case of “Future Value”. Each collected data has the ItemID, recent acquired time, data value and quality flag (Good, Bad or Questionable) to be displayed.
Display Data
By clicking “Display Data” of “Time Series” pull down menu or by double-clicking the grid of the data grid, acquired data is displayed on the “Time Series” window. Up to three Time Three windows are displayed at the same time. If the number of data sample is more than 30, the scroll bar is available.
By double-clicking the row of the dosplayed data, “Time Series” window is also displayed.
