P0922YK FBM201d工控备件模块
任何数字类型都可以输入以下值之一：•十进制整数，可选带符号，例如123。•例如，十六进制整数前面是0x，0x123A，或者后面是字母h，123Ah。接受大写和小写字母（A..F、H、X、A..F、H、X）。•二进制整数后跟字母b，例如1001 0001 b。接受大写和小写字母（B，B），并且可以包含空格。•用于自适应编程的参数指针，例如+0.1.4.0。它由符号（+或-）、组（0-255）、索引（0-255）和位数（0-31）组成。字段之间以句点分隔。负号表示反转。•用于自适应编程的常量，例如C.123。它由字母C后跟句点和常量值组成。接受大写和小写字母（C，C）。该值前面可以有空格。该值是一个介于-32768…32767之间的整数。如上所述，可以输入十进制、十六进制或二进制数。•可选的有符号实数，以可选的指数结尾，前面是E或E。指数可以有符号。请注意，无论区域设置如何，十进制符号都是句点。示例：1.2、-1.23E-3、1e3。输入的值将转换为项目的值类型。如果需要，实数四舍五入为整数。笔记无符号整数显示为十六进制数，如果要以十六进制输入，则始终需要0x前缀或字母h后缀。因此，输入123A是错误的。输入123是可以接受的，但将显示7B而不是123，因为它被视为十进制，而不是十六进制。如果希望显示123h（十六进制），则应输入0x123或123h。布尔值或枚举值将显示一个带有下拉列表的对话框。注意，如果当前值超出范围，则编辑字段显示为空。参数、信号和故障4-82 DriveWindow 2要获得所有可接受值的列表，请单击编辑字段右侧的向下箭头。下拉列表中也可能有一个滚动条，您可以使用它滚动浏览所有备选方案。要选择备选方案，请单击它。您也可以在编辑字段中键入所选内容，只要拼写与下拉列表中显示的完全相同即可。请注意，DriveWindow仅允许您在提供的备选方案中进行选择。无法将枚举参数更改为DriveWindow中的值超出范围。然而，项目最初在驱动器中可以具有这样的值。无论显示什么类型的对话框，当编辑字段中有新值时，单击“确定”按钮。如果要取消操作，也可以单击“取消”按钮。单击“确定”按钮时，DriveWindow、OPC服务器或驱动器会检查该值。如果发现任何错误，甚至通信错误，都会通知您：单击“确定”按钮将返回对话框，其中包含您在编辑字段中输入的值。现在，您可以更正值并重试，或取消操作。参数、信号和故障驱动器窗口2 4-83如果驱动器接受了新值，并且项目可读，则即使项目未联机，也会从驱动器读取该值并在项目集窗格中更新。
Any numerical type can be entered a one of the following: • Decimal integer, optionally signed, 123, for example. • Hexadecimal integer preceded by 0x, 0x123A, for example, or followed by letter h, 123Ah, for example. Accepts both upper and lower case letters (A..F, H, X, a..f, h, x). • Binary integer followed by letter b, 1001 0001 b, for example. Accepts both upper and lower case letters (B, b) and can contain spaces. • Parameter pointer for adaptive programming, +.1.4.0, for example. It consists of sign (+ or -), group (0-255), index (0-255), and bit number (0-31). Fields are separated from each other by a period. Negative sign means inversion. • Constant for adaptive programming, C. 123, for example. It consists of letter C followed by period and the value of the constant. Accepts both upper and lower case letters (C, c). The value can be preceded by spaces. The value is an integer between -32768...32767. It can be entered as decimal, hexadecimal, or binary number as presented above. • Optionally signed real number ending with optional exponent, which is preceded by E or e. The exponent can be signed. Note that the decimal symbol is period regardless the regional settings. Examples: 1.2, -1.23E-3, 1e3. The value entered is converted to the value type of the item. Real numbers are rounded to integers, if needed. Note! Unsigned integers, which are shown as hexadecimal numbers, always require the 0x prefix or letter h postfix, if you want to enter them in hexadecimal. Thus, entering 123A is an error. Entering 123 is accepted, but will show 7B instead of 123, because it is regarded as decimal, not hexadecimal. You should enter 0x123 or 123h, if you want 123h (hexadecimal) to be shown. A Boolean value or an enumerated value presents a dialog box with a drop-down list. Note that if the current value is out of bounds, the edit field is shown empty. Parameters, Signals, and Faults 4-82 DriveWindow 2 To get the list of all acceptable values dropped, click the down arrow to the right of the edit field. There may also be a scrollbar in the drop-down list, with which you can scroll through all the alternatives. To select an alternative, click it. You can type you selection into the edit field, too, as far as you spell it exactly as it is shown in the drop-down list. Note that DriveWindow allows you to select only among the presented alternatives. It is not possible to change an enumerated parameter to have a value out of bounds in DriveWindow. An item can initially have such a value in a drive, however. Whatever kind of dialog box was shown, click the OK button, when you have the new value in the edit field. You can also click the Cancel button, if you want to cancel the operation. When you click the OK button, the value is checked either by DriveWindow, the OPC Server, or the drive. If any errors are found, even communication errors, you are informed about it: Clicking the OK button brings back the dialog box with the value you entered into the edit field. Now you can correct your value and try again, or cancel the operation. Parameters, Signals, and Faults DriveWindow 2 4-83 If the new value was accepted by the drive, and the item is readable, the value is read back from the drive and updated in the item sets pane, even if the item is not on-line.
