A-B 80190-220-01-R控制器
按照以下步驟啟用Datalinks以寫(xiě)入數(shù)據(jù)。
1.僅設(shè)置所需數(shù)量的連續(xù)控制器的值，以驅(qū)動(dòng)向驅(qū)動(dòng)器寫(xiě)入數(shù)據(jù)所需的數(shù)據(jù)鏈路包含在網(wǎng)絡(luò)I/O連接中。
2.重置選項(xiàng)模塊；參見(jiàn)第49頁(yè)重置選項(xiàng)模塊。
3.由于邏輯命令和參考總是用在選項(xiàng)中模塊，配置驅(qū)動(dòng)器中的參數(shù)以接受邏輯選項(xiàng)模塊中的命令和引用。當(dāng)使用通過(guò)選項(xiàng)模塊進(jìn)行速度參考的控制器，在驅(qū)動(dòng)器中設(shè)置兩個(gè)字段參數(shù)545-[Speed Ref A Sel]：
a、 設(shè)置驅(qū)動(dòng)器的端口字段（例如，0-PowerFlex 755）。
b、 設(shè)置參數(shù)字段以指向選項(xiàng)所在的驅(qū)動(dòng)器端口模塊已安裝（對(duì)于本例，端口4參考）。
此外，還要驗(yàn)證驅(qū)動(dòng)器中的掩碼參數(shù)（例如，參數(shù)324-[Logic Mask]）配置為接收所需的來(lái)自選項(xiàng)模塊的邏輯。有關(guān)詳細(xì)信息，請(qǐng)參閱驅(qū)動(dòng)器文檔。
完成上述步驟后，選項(xiàng)模塊準(zhǔn)備接收輸入數(shù)據(jù)并將狀態(tài)數(shù)據(jù)傳輸?shù)街骺仄鳎刂破鳎?br/>
接下來(lái)，配置控制器識(shí)別I/O并將其傳輸至選項(xiàng)模塊。見(jiàn)第4章，配置I/O。
啟用數(shù)據(jù)鏈接以讀取數(shù)據(jù)
控制器輸入圖像（驅(qū)動(dòng)器到控制器輸入）可以有0到16其他32位參數(shù)（Datalinks）。它們是使用主機(jī)配置的參數(shù)17-[DL To Net 01]至32-[DL-To Net 16]。的數(shù)量
當(dāng)前使用的數(shù)據(jù)鏈路由控制器中的連接大小控制?？匆?jiàn)有關(guān)更多信息，請(qǐng)參閱第4章中相應(yīng)的控制器示例部分設(shè)置連接大小。使用ControlLogix控制器和通用配置文件時(shí)，配置Datalink參數(shù)現(xiàn)在如本節(jié)所述。
主機(jī)參數(shù)17-[DL To Net 01]至32-[DL-To Net 16]配置驅(qū)動(dòng)器、選項(xiàng)模塊或任何其他連接的外圍設(shè)備中的哪些參數(shù)將值發(fā)送到網(wǎng)絡(luò)。PowerFlex 20-HIM-A6或20-HIM-C6SHIM、DriveExplorer軟件或DriveExecutive軟件可用于選擇驅(qū)動(dòng)器或外圍設(shè)備（按端口號(hào)）和參數(shù)（按名稱(chēng)）。作為替補(bǔ)方法，則可以使用以下公式按數(shù)字手動(dòng)設(shè)置參數(shù)值：To Net參數(shù)值=（10000*端口號(hào)）+（發(fā)起參數(shù)號(hào)）
例如，假設(shè)您想使用主機(jī)參數(shù)17-[DL to Net 01]來(lái)讀取插入驅(qū)動(dòng)器端口6的可選I/O模塊的參數(shù)2。使用公式中，主機(jī)參數(shù)17-[DL To Net 01]的值為（10000*6）+ (2) = 60002.按照以下步驟啟用Datalinks讀取數(shù)據(jù)。
1.僅將所需數(shù)量的連續(xù)驅(qū)動(dòng)器的值設(shè)置為從驅(qū)動(dòng)器讀取數(shù)據(jù)所需的控制器數(shù)據(jù)鏈路包含在網(wǎng)絡(luò)I/O連接中。
2.重置選項(xiàng)模塊；參見(jiàn)第49頁(yè)重置選項(xiàng)模塊。選項(xiàng)模塊配置為將輸出數(shù)據(jù)發(fā)送到主控制器。
現(xiàn)在必須配置控制器，以識(shí)別I/O并將其傳輸?shù)竭x項(xiàng)模塊。參見(jiàn)第4章，配置I/O。
Follow these steps to enable Datalinks
to write data. 1. Set the values of only the required number of contiguous controller-todrive Datalinks needed to write data to the drive and that are to be included in the network I/O connection. 2. Reset the option module; see Resetting the Option Module on page 49. 3. Since the Logic Command and Reference is always used in the option module, configure the parameters in the drive to accept the Logic Command and Reference from the option module. When using the controller for speed reference via the option module, set two fields in drive Parameter 545 - [Speed Ref A Sel]: a. Set the Port field for the drive (for example, 0 - PowerFlex 755). b. Set the Parameter field to point to the drive port in which the option module is installed (for this example, Port 4 Reference). Also, verify that the mask parameters in the drive (for example, Parameter 324 - [Logic Mask]) are configured to receive the desired logic from the option module. See the drive documentation for details. After the above steps are complete, the option module is ready to receive input data and transfer status data to the master (controller). Next, configure the controller to recognize and transmit I/O to the option module. See Chapter 4, Configuring the I/O. Enabling Datalinks To Read Data The controller input image (drive-to-controller inputs) can have 0 to 16 additional 32-bit parameters (Datalinks). They are configured using Host Parameters 17 - [DL To Net 01] through 32 - [DL To Net 16]. The number of Datalinks actively used is controlled by the connection size in the controller. See the respective controller example sections in Chapter 4 for more information on setting the connection size.
When using a ControlLogix controller
and the Generic Profile, configure the Datalink parameters now as described in this section. Host Parameters 17 - [DL To Net 01] through 32 - [DL To Net 16] configure which parameters in the drive, option module, or any other connected peripheral send the values to the network. The PowerFlex 20-HIM-A6 or 20-HIM-C6S HIM, DriveExplorer software, or DriveExecutive software can be used to select the drive or peripheral by port number and the parameter by name. As an alternate method, the parameter value can be set manually by number using this formula: To Net Parameter Value = (10000 * Port Number) + (Origination Parameter Number) For example, suppose you want to use Host Parameter 17 - [DL To Net 01] to read Parameter 2 of an optional I/O module plugged into drive Port 6. Using the formula, the value for Host Parameter 17 - [DL To Net 01] would be (10000 * 6) + (2) = 60002. Follow these steps to enable Datalinks to read data. 1. Set the values of only the required number of contiguous drive-tocontroller Datalinks needed to read data from the drive and that are to be included in the network I/O connection. 2. Reset the option module; see Resetting the Option Module on page 49. The option module is configured to send output data to the master (controller). You must now configure the controller to recognize and transmit I/O to the option module. See Chapter 4, Configuring the I/O.
