CI532V02接口卡
DIP開關(guān)位置J892接口設(shè)備在用于設(shè)置ASCI設(shè)備地址和ASCII通信的模塊參數(shù)。
如果您想在此放置時支持ASCII設(shè)備，ASCII開關(guān)在將模塊安裝到I/O外殼中之前，必須進行設(shè)置。
J890和J892 RIO接口模塊的表面都有一組LED指示模塊和一個或兩個BNC電纜端口的RIO處理狀態(tài)用于將drop連接到RIO網(wǎng)絡(luò)。J892有額外的LED指示燈，指示ASCII設(shè)備處理狀態(tài)插座和一對25針D-shell內(nèi)螺紋端口，用于連接ASCII設(shè)備下降。
注意：前面板上的LED指示燈也提供診斷功能信息各種閃爍模式指示RIO接口中檢測到的錯誤和/或在ASCII接口中。
用戶連接任何支持S908 RIO網(wǎng)絡(luò)的984可編程控制器都可以使用800_系列I/O在其任何或所有遠程丟包，以及的任何遠程丟包800系列I/O可以使用J890或J892作為下拉接口模塊。
J890/J892接口模塊與所有800系列I/O模塊兼容
用于S908 RIO網(wǎng)絡(luò)，可支持多達1024個輸入位和1024個輸出位一滴（取決于前端控制器的性能）。
J890/J892接口是一個1.5插槽模塊，設(shè)計用于安裝在兩個插槽中緊靠主電源右側(cè)，在主殼體中一滴。
接口通過drop向800系列I/O發(fā)送數(shù)據(jù)和接收來自800系列I/O的數(shù)據(jù)底板；它通過RIO電纜系統(tǒng)。
除了管理掉線內(nèi)和RIO網(wǎng)絡(luò)上的I/O數(shù)據(jù)流外，J890/J892還用于定義RIO網(wǎng)絡(luò)上的drop地址。每個該模塊配有一組DIP開關(guān)，您可以使用這些開關(guān)設(shè)置獨特的下降住址J982還提供了第二組DIP開關(guān)，用于指定ASCII設(shè)備地址。交換機組的位置及其尋址方案
在第230頁的P890和P892投遞地址開關(guān)設(shè)置中定義J892 ASCII設(shè)備的DIP開關(guān)設(shè)置，第212頁。
當(dāng)J890/J892接口模塊安裝在drop中后，模塊將對自身執(zhí)行一組置信度測試。
如果在模塊的RIO處理部分、RIO LED中檢測到任何故障在前面板上會顯示錯誤代碼的閃爍模式。
DIP Switch Location
J892 Interface devices have an additional set of DIP switches located at the back of the module for setting ASCI device addresses and ASCII communication parameters. If you want to support ASCII devices at this drop, the ASCII switch setting must be made before the module is installed in the I/O housing.On the face of both the J890 and J892 RIO interface modules are a set of LEDs that indicate the RIO processing status of the module and one or two BNC cable ports used to connect the drop to the RIO network.The J892 has additional LEDs that indicate the ASCII device processing status at the drop and a pair of 25-pin, D-shell, female ports for connecting ASCII devices at the drop. NOTE: The LED indicators on the front panels also provide diagnostic information.Various flash patterns indicate errors detected in the RIO interface and/or in the ASCII interface.
When power is applied to the I/O housing after the J890/J892 interface module has been installed in the drop, the module performs a set of confidence tests on itself. If any faults are detected in the RIO processing portion of the module, the RIO LEDs on the front panel will display a flash pattern of error codes.
User Connections
Any 984 programmable controller that supports the S908 RIO network can employ 800_series I/O at any or all of its remote drops, and any remote drop of 800_series I/O can use a J890 or J892 as the drop interface module. The J890/J892 Interface modules are compatible with all 800 series I/O modules used in a S908 RIO network and may support up to 1024 input and 1024 output bits in a drop (depending on the capability of the head-end controller). A J890/J892 Interface is a 1.5 slot module designed to be installed in the two slots immediately to the right of the primary power supply in the primary housing of a drop. The Interface sends data to and receives data from the 800 series I/O via the drop’s backplane; it communicates with the RIO processing unit in the controller via the RIO cable system. In addition to managing the I/O data flow within the drop and over the RIO network, a J890/J892 is also used to define the address of the drop on the RIO network. Each module is equipped with a set of DIP switches with which you can set a unique drop address. The J982 also provides a second set of DIP switches for specifying ASCII device addresses. The locations of the switch packs and their addressing scheme are defined in P890 and P892 Switch Settings for the Drop Address, page 230 and J892 DIP Switch Settings for ASCII Devices, page 212.
