HONEYWELL 51403519-160/N03W31-S0082模塊,卡件
操作要求
1、避免出現(xiàn)以下情況：-GNIU的增強(qiáng)診斷模式設(shè)置為啟用
-GNIU與Genius總線控制器聯(lián)機(jī)。
-串行通信（程序員操作：下載遠(yuǎn)程
輸入/輸出配置，驗證平等性，明確配置；或Winloader）正在發(fā)生。
在嘗試任何操作之前，斷開GNIU與Genius總線的連接如果硬件配置具有增強(qiáng)的診斷模式設(shè)置為Enabled（啟用）當(dāng)前已安裝或?qū)惭b在GNIU中。
HONEYWELL 51403519-160/N03W31-S0082模塊完成串行通信后，斷開串行電纜從GNIU的擴(kuò)展端口。然后可以重新連接GNIU去Genius巴士。
從Genius總線斷開GNIU的另一種方法是關(guān)閉或斷開總線上所有Genius總線控制器的電源。
2.不允許在GNIU上強(qiáng)制輸入/輸出點。
3.在增強(qiáng)診斷模式下，GNIU持續(xù)運(yùn)行
正常運(yùn)行期間在后臺進(jìn)行診斷測試。這些診斷導(dǎo)致GNIU對干擾更敏感
在Genius巴士上。當(dāng)Genius總線干擾或自發(fā)硬件故障導(dǎo)致診斷測試宣布
一個錯誤，GNIU停止了Genius總線上的通信嘗試重置自身。通信中斷導(dǎo)致主機(jī)PLC記錄設(shè)備丟失故障并默認(rèn)受影響的輸入（根據(jù)主機(jī)的配置）。GMR PLC將忽略與該GNIU相關(guān)的通道。如果GNIU是它能夠自我恢復(fù)，幾次嘗試恢復(fù)正常運(yùn)行幾秒鐘后。如果成功，主機(jī)PLC將記錄
Operating Requirements
1. Avoid situations where all of the following are true at the same time:
- the GNIU's Enhanced Diagnostics Mode is set to Enabled
- the GNIU is online with a Genius Bus Controller.
- serial communications (programmer operations: download remote
I/O configuration, verify equality, clear configuration; or Winloader)
are taking place.
Disconnect the GNIU from the Genius bus before attempting any
serial communications if a hardware configuration with Enhanced
Diagnostics Mode set to Enabled either is currently installed or will
be installed in the GNIU.
After completing serial communications disconnect the serial cable
from the GNIU’s expansion port. The GNIU can then be reattached
to the Genius bus.
An alternative to disconnecting the GNIU from the Genius bus is to
power off or disconnect all of the Genius Bus Controllers on the bus.
2. Forcing an I/O point on the GNIU is not permitted.
3. In Enhanced Diagnostics mode, the GNIU continually runs extensive
diagnostic tests in the background during normal operation. These
diagnostics cause the GNIU to be more sensitive to disturbances
on the Genius bus. When a Genius bus disturbance or
spontaneous hardware failure causes a diagnostic test to declare
an error, the GNIU stops communicating on the Genius bus and
attempts to reset itself. The loss of communications causes the
host PLC(s) to log a Loss of Device fault and default the affected
inputs (according to the host’s configuration). GMR PLCs will
disregard the channels associated with that GNIU. If the GNIU is
able to revive itself, it tries to resume normal operation several
seconds later. If this is successful, the host PLC(s) will log an
