ODC塊是上使用的五個(gè)操作員顯示器之一每個(gè)循環(huán)一個(gè)，用于配置本地操作員顯示來自遠(yuǎn)程操作員的功能和網(wǎng)絡(luò)參數(shù)與回路相關(guān)的工作站。查看i|ware PC下一頁的面板。
固件1.30及更高版本中包含以下功能。1.一個(gè)新參數(shù)，視圖OD，當(dāng)設(shè)置為是時(shí)默認(rèn)設(shè)置，允許查看操作員顯示并使用循環(huán)按鈕本地訪問。在某些情況下在這種情況下，可能需要僅查看顯示或操作網(wǎng)絡(luò)工作站的參數(shù)，不允許從本地操作或查看控制回路陳列此處，參數(shù)應(yīng)設(shè)置為“否”。
2.當(dāng)循環(huán)事件激活時(shí)，輸出LE為高（1）。輸出當(dāng)站錯(cuò)誤激活時(shí)，SE為高。
3.循環(huán)#（此參數(shù)為版本中的MB索引1.21）用于索引對(duì)Modbus的讀取和寫入?yún)?shù)。LIL具有25個(gè)參數(shù)：C1S、C2S、C3S，..C25S。選擇ODC塊后，以及循環(huán)#已配置，相應(yīng)的C#LIL參數(shù)將包含LIL起始通道（n）地方必須輸入循環(huán)#才能啟用LIL或Modbus通信。
過程/設(shè)定點(diǎn)和閥門的范圍指針必須配置條形圖以定義P、S和V的變量輸入。如果這些參數(shù)不是配置后，將使用工程圖縮放條形圖范圍為0.00到100.00。X和Y的范圍指針定義顯示的小數(shù)點(diǎn)位置和單位代碼。
該信息還定義了循環(huán)的縮放通過提供給遠(yuǎn)程工作站的信息網(wǎng)絡(luò)（即Modbus或LIL）。
輸入變量P、S、V、X和Y顯示在數(shù)字顯示中，使用工程單位和首選范圍指針的DPP。在BATOT內(nèi)配置時(shí)，也將顯示BATOT的總計(jì)塊如果值大于DPP參數(shù)允許的值，小數(shù)點(diǎn)將移動(dòng)以允許顯示

有關(guān)使用優(yōu)先級(jí)1至5的顯示動(dòng)作的說明，請(qǐng)參見第9節(jié)“操作”。
水平條形圖可以選擇為直接作用或反向作用。此功能允許它始終指示完全點(diǎn)亮?xí)r打開閥門。基本面板上的標(biāo)簽是固定的，但粘貼標(biāo)簽可用于更改適應(yīng)癥。V NET AC參數(shù)允許為直接或反向動(dòng)作設(shè)置LxVI網(wǎng)絡(luò)參數(shù)。
這使得HMI上的閥桿能夠與面板上的閥條類似地操作。左欄和右欄應(yīng)相應(yīng)設(shè)置標(biāo)簽（例如，左=打開，右=關(guān)閉）。操作員顯示器必須配置為將控制器回路數(shù)據(jù)映射到網(wǎng)絡(luò)數(shù)據(jù)。環(huán)路網(wǎng)絡(luò)數(shù)據(jù)已映射

ODC blocks are one of five operator displays that are used on a one per loop basis to configure the local operator display functions and network parameters from a remote operator workstation associated with the loop. See the i|ware PC faceplate on the next page. The following features are in firmware 1.30 and higher. 1. A new parameter, VIEW OD, when set to YES, the default setting, enables the operator display to be viewed and accessed locally using the LOOP button. In some cases, it may be desired to view only display or operation parameters with a network workstation and not allow operation or viewing of the control loop from the local display. Here the parameter should be set to NO. 2. Output LE is high (1) when a loop event is active. Output SE is high when a station error is active. 3. The LOOP # (this parameter was MB INDEX in version 1.21) is used to index reads and writes to Modbus parameters. The LIL has 25 parameters: C1S, C2S, C3S, ..... C25S. When an ODC block has been selected and the LOOP # has been configured, the corresponding C#S LIL parameter will contain the LIL starting Chan (n) location. The LOOP# must be entered to enable either LIL or Modbus communications. Range pointers for both the process/setpoint and valve bargraphs must be configured to define the range of the variable inputs to P, S, and V. If these parameters are not configured, the bargraphs will be scaled using the engineering range of 0.00 to 100.00. The range pointer for X and Y define the displayed decimal point position and the units code. This information also defines the scaling of the loop information provided to a remote workstation over the network (i.e. Modbus or LIL). Input variables P, S, V, X, and Y are shown in the numeric display, using the engineering UNITS and the preferred DPP of the range pointer. The Total from the BATOT will also be displayed when configured within the BATOT block. If a value is greater than allowed by the DPP parameter, the decimal point will be shifted to allow the display to show the full number, until it exceeds the maximum available digits, at which time it will indicate over range. When input U1 or U2 goes high (1), the 8-character user status (U_STATUS) will be displayed as configured by the status priority (U_ PRIOR). A priority of 0 will disable that status function setting the bits in the status word to 0. See Section 9 Operation for a description of display actions using priorities 1 to 5. The horizontal bargraph can be selected as direct or reverse acting. This feature allows it to always indicate an OPEN valve when fully lit. The labels on the basic faceplate are fixed, but paste on labels can be used to change the indications. The V NET AC parameter allows the LxVI network parameter to be set for direct or reverse action. This enables the valve bar on the HMI to operate similar to the valve bar on the faceplate. The left and right bar labels should be set accordingly (e.g. Left = “OPEN & Right = CLOSE). An operator display must be configured to map controller loop data to network data. Loop network data is mapped into registers or coils when the standard Modbus interface is used and to channels/parameters when the optional LIL interface has been added. Mappings for both Modbus and LIL are listed in the tables included in the ‘Network
