140CRP93100处理器接口模块
故障排除如果模块发生故障,请使用以下故障排除步骤通电。如果这些步骤不能解决问题,请联系ProSoft技术技术支持。
处理器错误
问题描述要采取的步骤
处理器故障验证模块是否插入已配置的插槽用于RSLogix I/O配置中的模块。
验证机架中的插槽位置是否已在中正确配置梯形逻辑。
处理器I/O指示灯闪光
这表明背板通信有问题。一个问题可能存在于处理器和任何已安装的I/O模块之间,而不仅仅是MVI56E-SIE。验证机架中的所有模块是否正在梯形图逻辑中配置。
模块错误
问题描述要采取的步骤
BP ACT LED(非MVI56E上显示模块)保持关闭或缓慢闪烁MVI56E模块
滚动LED显示屏:<背板状态>
条件读取ERR这表明背板传输操作失败。连接到模块的配置/调试端口进行检查。
要建立背板通信,请验证以下项目:
处理器处于RUN或REM RUN模式。
背板驱动程序加载到模块中。
该模块配置为读写数据块传输。
梯形图逻辑处理所有读写块情况。
模块在处理器I/O配置中正确配置和梯形逻辑。OK LED保持红色程序已停止或发生严重错误。连接到配置/调试端口以查看模块是否正在运行。如果程序已停止,关闭机架电源,从机架中取出卡,然后重新插入,然后恢复机架电源。清除故障条件通常,如果模块前面的OK LED变为红色超过十次秒,模块中检测到硬件问题或程序已退出。
要清除此情况,请执行以下步骤:
1关闭机架电源。
2从机架中取出卡。
3确认所有跳线设置正确。
4如果模块需要Compact Flash卡,请验证是否安装了该卡正确
5将卡重新插入机架,然后重新打开电源。
6验证从ControlLogix控制器。
如果模块的OK LED(正常发光二极管)未变成绿色,请确认模块已插入
完全装入机架。如果这不能解决问题,请联系ProSoft Technology技术支持。
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.
