3BHB003041R0101控制器,UFC719AE01模块
扫描仪上有三个LED，COMM LED、SYS LED和OK LED。有关详细信息信息，请参阅第4.3节，PROFIBUS LED和显示状态。
通信LED COMM LED指示PROFIBUS网络的运行状况，当PROFIBUS扫描仪通过配置工具进行令牌传递或监控。LED为如果没有网络错误，则为纯绿色。如果发生网络错误，通信LED可以关闭、呈红色稳定显示，或在绿色时周期性闪烁红色。
3BHB003041R0101控制器系统LED通电时，SYS LED先亮红色，然后亮绿色两秒钟。当它发光时，你可以进入系统配置模式，用于将新固件下载到扫描仪。
当扫描仪充当主机时，SYS LED指示与的通信状态PROFIBUS从站。红色稳定的SYS LED指示一个或多个从设备出错，且稳定绿色表示在运行模式下正在网络上扫描所有从属设备。当它是琥珀色时，所有从机正在清除模式下扫描（输出均为零）。
当扫描仪作为从设备时，SYS LED指示与的通信状态PROFIBUS主机。当SYS LED呈红色稳定亮起时，PROFIBUS主控不再显示正在扫描，当它呈绿色时，PROFIBUS主控器正在成功扫描模块作为运行模式下的从机。琥珀色SYS LED指示PROFIBUS主机正在扫描在清除模式下，模块作为从属模块。
There are three LEDs on the scanner, the COMM LED, SYS LED and the OK LED. For detailed
information, refer to Section 4.3, PROFIBUS LED and Display States.
COMM LED
The COMM LED indicates the health of the PROFIBUS network and flashes green when the
PROFIBUS scanner is token passing or being monitored via the Configuration Tool. The LED is
solid green when there are no network errors. If a network error occurs, the COMM LED can
either be off, solid red, or flashing red periodically while it is green.
SYS LED
At powerup, the SYS LED shines red, then green for two seconds. While it shines, you can enter
System Configuration mode to download new firmware to the scanner.
When the scanner acts as a Master, the SYS LED indicates the communication status with
PROFIBUS slaves. A solid red SYS LED indicates that one or more slaves are in error, and solid
green means that all slaves are being scanned on the network in Run mode. When it’s amber, all
slaves are being scanned in Clear mode (outputs are all zeroes).
When the scanner acts as a slave, the SYS LED indicates the communication status with the
PROFIBUS Master. When the SYS LED is solid red, the PROFIBUS Master is no longer
scanning, and when it is solid green, the PROFIBUS Master is successfully scanning the module
as a slave in Run mode. An amber SYS LED indicates that the PROFIBUS Master is scanning
the module as a slave in Clear mode.
