140CRP93100處理器接口模塊
故障排除如果模塊發(fā)生故障，請使用以下故障排除步驟通電。如果這些步驟不能解決問(wèn)題，請聯(lián)系ProSoft技術(shù)技術(shù)支持。
處理器錯誤
問(wèn)題描述要采取的步驟
處理器故障驗證模塊是否插入已配置的插槽用于RSLogix I/O配置中的模塊。
驗證機架中的插槽位置是否已在中正確配置梯形邏輯。
處理器I/O指示燈閃光
這表明背板通信有問(wèn)題。一個(gè)問(wèn)題可能存在于處理器和任何已安裝的I/O模塊之間，而不僅僅是MVI56E-SIE。驗證機架中的所有模塊是否正在梯形圖邏輯中配置。
模塊錯誤
問(wèn)題描述要采取的步驟
BP ACT LED（非MVI56E上顯示模塊）保持關(guān)閉或緩慢閃爍MVI56E模塊
滾動(dòng)LED顯示屏：<背板狀態(tài)>
條件讀取ERR這表明背板傳輸操作失敗。連接到模塊的配置/調試端口進(jìn)行檢查。
要建立背板通信，請驗證以下項目：
? 處理器處于RUN或REM RUN模式。
? 背板驅動(dòng)程序加載到模塊中。
? 該模塊配置為讀寫(xiě)數據塊傳輸。
? 梯形圖邏輯處理所有讀寫(xiě)塊情況。
? 模塊在處理器I/O配置中正確配置和梯形邏輯。OK LED保持紅色程序已停止或發(fā)生嚴重錯誤。連接到配置/調試端口以查看模塊是否正在運行。如果程序已停止，關(guān)閉機架電源，從機架中取出卡，然后重新插入，然后恢復機架電源。清除故障條件通常，如果模塊前面的OK LED變?yōu)榧t色超過(guò)十次秒，模塊中檢測到硬件問(wèn)題或程序已退出。
要清除此情況，請執行以下步驟：
1關(guān)閉機架電源。
2從機架中取出卡。
3確認所有跳線(xiàn)設置正確。
4如果模塊需要Compact Flash卡，請驗證是否安裝了該卡正確
5將卡重新插入機架，然后重新打開(kāi)電源。
6驗證從ControlLogix控制器。
如果模塊的OK LED（正常發(fā)光二極管）未變成綠色，請確認模塊已插入
完全裝入機架。如果這不能解決問(wèn)題，請聯(lián)系ProSoft Technology技術(shù)支持。
Troubleshooting
Use the following troubleshooting steps if problems are encountered when the module is
powered up. If these steps do not resolve the problem, please contact ProSoft
Technology Technical Support.
Processor Errors
Problem description Steps to take
Processor fault Verify that the module is plugged into the slot that has been configured
for the module in the I/O Configuration of RSLogix.
Verify that the slot location in the rack has been configured correctly in
the ladder logic.
Processor I/O LED
flashes
This indicates a problem with backplane communications. A problem
could exist between the processor and any installed I/O module, not just
the MVI56E-SIE. Verify that all modules in the rack are correctly
configured in the ladder logic.
Module Errors
Problem description Steps to take
BP ACT LED (not
present on MVI56E
modules) remains OFF
or blinks slowly
MVI56E modules with
scrolling LED display:
Clearing a Fault Condition
Typically, if the OK LED on the front of the module turns RED for more than ten seconds, a hardware problem has been detected in the module or the program has exited. To clear the condition, follow these steps: 1 Turn off power to the rack. 2 Remove the card from the rack. 3 Verify that all jumpers are set correctly. 4 If the module requires a Compact Flash card, verify that the card is installed correctly. 5 Re-insert the card in the rack and turn the power back on. 6 Verify correct configuration data is being transferred to the module from the ControlLogix controller. If the module's OK LED does not turn GREEN, verify that the module is inserted completely into the rack. If this does not cure the problem, contact ProSoft Technology Technical Support.
