如果RIO網絡前端的Unity控制器支持本地I/O丟棄和遠程I/O，然后丟棄地址#1為本地丟棄保留第一個遠程投遞地址為投遞#2。如果Unity控制器沒有支持本地I/O，第一個遠程拖放地址為拖放#1。有關完整列表984控制器及其I/O支持功能，請參閱Modicon Remote I/O系統規劃和安裝指南（890 USE 101 00）。

J892接口設備在用于設置ASCI設備地址和ASCII通信的模塊參數。如果您想在此放置時支持ASCII設備，ASCII開關

在將模塊安裝到I/O外殼中之前，必須進行設置。

使用者連接任何支持S908 RIO網絡的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網絡，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，設計用于安裝在兩個插槽中緊靠主電源右側，在主殼體中一滴。

接口通過drop向800系列I/O發送數據和接收來自800系列I/O的數據底板；

它通過RIO電纜系統

除了管理掉線內和RIO網絡上的I/O數據流外，J890/J892還用于定義RIO網絡上的drop地址。

每個該模塊配有一組DIP開關，您可以使用這些開關設置獨特的下降住址J982還提供了第二組DIP開關，用于指定ASCII設備地址。

當J890/J892接口模塊安裝在drop中后，模塊將對自身執行一組置信度測試。

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。

If the Unity controller

 at the head end of the RIO network supports both a local I/O drop and remote I/O, then drop address # 1 is reserved for the local drop and the first remote drop is addressed as drop # 2. If the Unity controller does not support local I/O, the first remote drop is addressed as drop # 1. For a complete list of 984 controllers and their I/O support capabilities, refer to the Modicon Remote I/ O System Planning and Installation Guide (890 USE 101 00).

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.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 & P892 Switch Settings for the Drop Address, p. 80 and J892 DIP Switch Settings for ASCII Devices, p. 60.
