BENTLY 106M1081-01通道繼電器模塊,106M1081-01產(chǎn)品顏色模塊需要屏蔽電纜來(lái)幫助減少電氣噪聲的影響聯(lián)軸器。在一端將每個(gè)屏蔽接地只有兩端接地的屏蔽形成接地回路，這可能導致模塊通信故障。從不將屏蔽連接到邏輯電路（這會(huì )引入噪聲進(jìn)入邏輯電路）。將屏蔽直接連接到機箱地此機箱接地連接在1734-232ASC RTB上不可用（可拆卸接線(xiàn)板）。
BENTLY 106M1081-01通道繼電器模塊在某一點(diǎn)上輸入/輸出系統，底盤(pán)接地可以在DIN導軌上進(jìn)行連接，在金屬面板上，DIN導軌安裝到用戶(hù)的輸入/輸出設備或安裝在用戶(hù)的輸入/輸出設備上。與ASCII模塊通信ASCII模塊用作串行總線(xiàn)的點(diǎn)總線(xiàn)前端裝置數據可以通過(guò)輪詢(xún)與主機交換，循環(huán)或狀態(tài)變化連接。位選通命令響應消息傳遞和未連接的消息管理器（UCMM）不是支持1. 該模塊生成和使用數據如下：設備在線(xiàn)，但在已建立狀態(tài)下沒(méi)有連接。綠色設備在線(xiàn)，連接處于建立狀態(tài)。在超時(shí)狀態(tài)下，一個(gè)或多個(gè)輸入/輸出連接呈紅色閃爍紅色關(guān)鍵鏈路故障-通信設備故障。檢測到設備阻止其在網(wǎng)絡(luò )上通信的錯誤。閃爍紅色/綠色通信故障設備-設備檢測到網(wǎng)絡(luò )訪(fǎng)問(wèn)錯誤，并且處于通信故障狀態(tài)。設備具有接收并接受了識別通信故障請求
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.
