PETLI01A工控模块系统备件
••预触发（ms），与触发设置子菜单中的预触发（毫秒）命令相同。双击设置名称将显示一个预触发对话框，您可以在其中更改触发事件之前当前数据记录器中保存的值的数量。该值以时间形式给出并显示，但数据记录器实际上使用了一个计数。•Trig Conditions，与Trig Settings子菜单中的Conditions命令相同。双击设置的名称会显示一个触发条件对话框，您可以在其中更改触发当前数据记录器的条件。•Trig Variable，与Trig Settings子菜单中的Variable命令相同。双击设置名称会显示一个Trig Variable（触发变量）对话框，您可以在其中更改用于触发当前数据记录器的变量的OPC地址。注意，OPC地址不带通道和节点，驱动器使用的名称（而非OPC地址）显示在值字段中。•Trig Level，与Trig Settings子菜单中的Level命令相同。双击设置名称会显示一个触发级别对话框，您可以在其中更改触发级别，该级别用于触发当前数据记录器。•触发滞后，与“触发设置”子菜单中的滞后命令相同。双击设置名称会显示一个Trig Hysteresis（触发滞后）对话框，您可以在其中更改触发级别的滞后，该触发级别用于触发当前数据记录器。•X轴长度，与数据记录器菜单的轴子菜单中的X轴长度命令相同。双击设置名称将显示一个X轴长度对话框，您可以在其中更改当前缩放级别下数据记录器图形的X轴长度（如果有）。•Y轴最大值，与数据记录器菜单的“轴”子菜单中的“Y轴最大”命令相同。双击设置名称会显示一个“Y轴最大值”对话框，在该对话框中，您可以更改当前缩放级别下数据记录器图形的Y轴最大值（如果有）。•Y轴最小值，与数据记录器菜单的“轴”子菜单中的“Y轴最小”命令相同。双击设置名称会显示一个Y轴最小值对话框，您可以在其中更改当前缩放级别下数据记录器图形的Y轴最小数值（如果有）。•通道1，…通道6，与数据记录器菜单缩放子菜单中的通道1，..通道6命令相同。根据在“图形首选项”（Graph Preferences）中选择的缩放方法，系数和偏移，或y=0和y=100时的值将显示在设置的值字段中。系数和偏移以系数*x+偏移的形式显示为公式。y=0和y=100处的值显示在括号（[]）内，用逗号分隔。双击设置的名称会向用户显示“通道缩放”对话框。更改系数和偏移量，用于在趋势显示窗格中绘制记录项目之前缩放其测量值。用户界面驱动窗口2 2-71注意，如果频道有要记录的项目，则项目的描述性名称将显示为设置的名称，而不是频道n。描述性名称是从驱动器获取的，而不是用户给定的名称。还请注意，驱动器中不存在的通道将n/a显示为设置的名称，并且值（缩放）为空。注意，如果设置被禁用，双击它会发出蜂鸣声。要从当前数据记录器中添加、更改或删除记录的项目，请参阅数据记录器菜单。粘贴命令和拖放也可用于将项目添加到自由频道中。请注意，频道设置的选择也可用于从监视器中删除受监视的项目。
Pre-Trig (ms), same as Pre-Trig (ms) command in the Trig Settings submenu. Doubleclicking the name of the setting presents a Pre-Trig dialog box, where you can change the number of values kept in the current datalogger before the triggering event. The value is given and shown as time, but the datalogger actually uses a count. • Trig Conditions, same as Conditions command in the Trig Settings submenu. Double-clicking the name of the setting presents a Triggering Conditions dialog box, where you can change the conditions, which trigger the current datalogger. • Trig Variable, same as Variable command in the Trig Settings submenu. Double-clicking the name of the setting presents a Trig Variable dialog box, where you can change OPC address of the variable, which is used in triggering the current datalogger. Note that the OPC address is given without channel and node, and the name used by the drive, not the OPC address, is shown in the value field. • Trig Level, same as Level command in the Trig Settings submenu. Double-clicking the name of the setting presents a Trig Level dialog box, where you can change the triggering level, which is used in triggering the current datalogger. • Trig Hysteresis, same as Hysteresis command in the Trig Settings submenu. Double-clicking the name of the setting presents a Trig Hysteresis dialog box, where you can change hysteresis of the triggering level, which is used in triggering the current datalogger. • X Axis Length, same as X Length command in the Axis submenu of the Datalogger menu. Double-clicking the name of the setting presents an X Axis Length dialog box, where you can change the x-axis length of the datalogger graph at current zooming level, if any. • Y Axis Maximum, same as Y Axis Maximum command in the Axis submenu of the Datalogger menu. Double-clicking the name of the setting presents a Y Axis Maximum dialog box, where you can change the y-axis maximum value of the datalogger graph at current zooming level, if any. • Y Axis Minimum, same as Y Axis Minimum command in the Axis submenu of the Datalogger menu. Double-clicking the name of the setting presents a Y Axis Minimum dialog box, where you can change the y-axis minimum value of the datalogger graph at current zooming level, if any. • Channel 1, ... Channel 6, same as Channel 1, ... Channel 6 command in Scaling submenu of the Datalogger menu. Depending on the scaling method selected in Graph Preferences, either the coefficient and offset, or values at y=0 and at y=100 are displayed in the value field of a setting. The coefficient and offset are displayed as a formula in form coefficient * x + offset. The values at y=0 and y=100 are displayed within brackets ([]), separated with comma. Double-clicking the name of a setting presents user a Channel Scaling dialog box. Changes the coefficient and the offset, which are used to scale the measured value of the logged item before it is drawn in the trend display pane. User Interface DriveWindow 2 2-71 Note that if a channel has an item to be logged, the descriptive name of the item is shown as the name of the setting instead of Channel n. The descriptive name is fetched from the drive, it is not the one given by the user. Note also that channels, which do not exist in the drive, show n/a as the name of the setting and the value (scaling) is empty. Note that if a setting is disabled, double-clicking it beeps. To add, change, or remove logged items from the current datalogger, see Datalogger menu. Paste command and drag and drop can also be used to add items into free channels. Note that selections of the channel settings can also be used to remove monitored items from the monitor.
