如果RIO网络前端的Unity控制器支持本地I/O丢弃和远程I/O，然后丢弃地址#1为本地丢弃保留第一个远程投递地址为投递#2。如果Unity控制器没有支持本地I/O，第一个远程拖放地址为拖放#1。有关完整列表984控制器及其I/O支持功能，请参阅Modicon Remote I/O系统规划和安装指南（890 USE 101 00）。

在将模块安装到I/O外壳中之前，必须进行设置。

使用者连接任何支持S908 RIO网络的984可编程控制器都可以使用800_系列I/O在其任何或所有远程丢包，以及的任何远程丢包800_系列I/O可以使用J890或J892作为下拉接口模块。

J890/J892接口模块与所有800系列I/O模块兼容用于S908 RIO网络，可支持多达1024个输入位和1024个输出位一滴（取决于前端控制器的性能）。

J890/J892接口是一个1.5插槽模块，设计用于安装在两个插槽中紧靠主电源右侧，在主壳体中一滴。

除了管理掉线内和RIO网络上的I/O数据流外，J890/J892还用于定义RIO网络上的drop地址。

每个该模块配有一组DIP开关，您可以使用这些开关设置独特的下降住址J982还提供了第二组DIP开关，用于指定ASCII设备地址。

当J890/J892接口模块安装在drop中后，模块将对自身执行一组置信度测试。

如果在模块的RIO处理部分、RIO LED中检测到任何故障在前面板上会显示错误代码的闪烁模式。

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.
