BENTLY 106M1081-01通道继电器模块,106M1081-01产品颜色模块需要屏蔽电缆来帮助减少电气噪声的影响联轴器。在一端将每个屏蔽接地只有两端接地的屏蔽形成接地回路，这可能导致模块通信故障。从不将屏蔽连接到逻辑电路（这会引入噪声进入逻辑电路）。将屏蔽直接连接到机箱地此机箱接地连接在1734-232ASC RTB上不可用（可拆卸接线板）。
BENTLY 106M1081-01通道继电器模块在某一点上输入/输出系统，底盘接地可以在DIN导轨上进行连接，在金属面板上，DIN导轨安装到用户的输入/输出设备或安装在用户的输入/输出设备上。与ASCII模块通信ASCII模块用作串行总线的点总线前端装置数据可以通过轮询与主机交换，循环或状态变化连接。位选通命令响应消息传递和未连接的消息管理器（UCMM）不是支持1. 该模块生成和使用数据如下：设备在线，但在已建立状态下没有连接。绿色设备在线，连接处于建立状态。在超时状态下，一个或多个输入/输出连接呈红色闪烁红色关键链路故障-通信设备故障。检测到设备阻止其在网络上通信的错误。闪烁红色/绿色通信故障设备-设备检测到网络访问错误，并且处于通信故障状态。设备具有接收并接受了识别通信故障请求
module requires shielded cable to help
reduce the effects of electrical noise
coupling. Ground each shield at one end
only. A shield grounded at both ends
forms a ground loop, which can cause
module communications to fault. Never
connect a shield to the common side of a
logic circuit (this would introduce noise
into the logic circuit).
Connect the shield directly to a chassis
ground. This chassis ground connection
is not available on the 1734-232ASC RTB
(Removable Terminal Block). On a POINT
I/O system, the chassis ground
connection can be made at the DIN Rail,
at the metal panel the DIN Rail is
mounted to, or at the user’s I/O device.Communicating with the ASCII Modules
The ASCII modules operate as the PointBus front-end to your serial
device. Data can be exchanged with the master through a polled,
cyclic, or change-of-state connection. Bit-Strobe Command Response
Messaging and the Unconnected Message Manager (UCMM) are not
supported1
. The module produces and consumes data as follows:Device is on-line but has no connections in the established state.
Green Device on-line and has connections in the established state.
Flashing Red One or more I/O connections in timed-out state
Red Critical link failure - failed communication device. Device detected
error that prevents it communicating on the network.
Flashing
Red/Green
Communication faulted device - the device has detected a network
access error and is in communication faulted state. Device has
received and accepted an Identify Communication Faulted Request
- long protocol message.
