远程模块故障排除
远程模块的诊断功能远程模块配备了许多诊断功能。其中一些功能成为仅当它们已通过I/O设置时才处于活动状态配置功能完全可用。设置和错误可以从相关频道进行询问。部分功能可用，请参阅模块说明。1） 关于设置和诊断数据，请参见模块说明和第A3.3章“读取I/O配置和模块上的诊断数据”。BE总线错误=总线故障，始终受到监控。这个模块未收到来自总线主设备的呼叫。
这可能有以下原因：
–CS31系统总线断开，短路或接线极性相反。
–中央单元未设置为“终结者”主，另见系统常数KW 00,00 in第A7.3章。
CI输入断线=断路（监控）
输入（如果已配置）。每个输入电路监控装置必须配备一个电阻20…30 k，例如与信号触点并联。CO切断输出线=断路（监控）输出（如果已配置）。每个输出都需要当ON信号为输出OL过载（始终受到监控）。
SC短路（始终受到监控）。UE单元错误=模块的内部错误（故障）（始终尽可能监控内部处理器检测到这一点）。远程模块中的故障排除
如果远程模块检测到，则LED亮起一个错误。远程模块提供详细的错误信息通过8个LED，按下测试按钮；看见以及模块说明。以下将对程序进行解释以ICSC 08 L1模块为例。第一次按下测试按钮后，选择通道E/A0（输入/输出0）：LED0闪烁。松开按钮后此通道通过黄色LED 0至7显示约3秒。
Troubleshooting on the remote modules
Diagnosis functions for the remote modules
The remote modules are equipped with a number of
diagnosis functions. Some of these functions become
active only if they have been set by means of the I/O
configuration
Feature is completely available. Settings and errors can be interrogated from the involved channel. () Feature is partly available, see module description. 1) Concerning the interrogation of settings and diagnosis data, see the module description and chapter A3.3 ”Reading I/O configuration and diagnosis data at the module”. BE Bus Error = Bus malfunction, always monitored. The module does not receive a call from the bus master. This may have the following reasons: – The CS31 system bus line is broken, short-circuited or wired with reversed polarity. – The central unit has< not been set as buster master, see also system constant KW 00,00 in chapter A7.3. CI Cut Wire of Inputs = Open circuit (monitoring) at inputs, if configured. Each input circuit to be monitored has to be equipped with a resistor of 20...30 k, e.g. in parallel to the signalling contact. CO Cut Wire of Outputs = Open circuit (monitoring) at outputs, if configured. Each output expects a minimum load of approx. 40 mA when an ON signal is output. OL Overload (is always monitored). SC Short circuit (is always monitored). UE Unit error = internal error (fault) of the module (always monitored in so far as the internal processor can detect this). Troubleshooting in the remote modules The LED lights up, if the remote module has detected an error. The remote module supplies detailed error information via the 8 LEDs , it the test button is pressed; see also the module descriptions. The procedure will be explained in the following for the module ICSC 08 L1 as an example. After the test button has been pressed for the first time, channel E/A0 (input/output 0) is selected: LED0 flashes. After the button has been released, The diagnosis data of this channel are shown via the yellow LEDs 0 to 7 for approx. 3 seconds.
