3BHB003041R0101控制器,UFC719AE01模塊
掃描儀上有三個LED，COMM LED、SYS LED和OK LED。有關(guān)詳細(xì)信息信息，請參閱第4.3節(jié)，PROFIBUS LED和顯示狀態(tài)。
通信LED COMM LED指示PROFIBUS網(wǎng)絡(luò)的運(yùn)行狀況，當(dāng)PROFIBUS掃描儀通過配置工具進(jìn)行令牌傳遞或監(jiān)控。LED為如果沒有網(wǎng)絡(luò)錯誤，則為純綠色。如果發(fā)生網(wǎng)絡(luò)錯誤，通信LED可以關(guān)閉、呈紅色穩(wěn)定顯示，或在綠色時周期性閃爍紅色。
3BHB003041R0101控制器系統(tǒng)LED通電時，SYS LED先亮紅色，然后亮綠色兩秒鐘。當(dāng)它發(fā)光時，你可以進(jìn)入系統(tǒng)配置模式，用于將新固件下載到掃描儀。
當(dāng)掃描儀充當(dāng)主機(jī)時，SYS LED指示與的通信狀態(tài)PROFIBUS從站。紅色穩(wěn)定的SYS LED指示一個或多個從設(shè)備出錯，且穩(wěn)定綠色表示在運(yùn)行模式下正在網(wǎng)絡(luò)上掃描所有從屬設(shè)備。當(dāng)它是琥珀色時，所有從機(jī)正在清除模式下掃描（輸出均為零）。
當(dāng)掃描儀作為從設(shè)備時，SYS LED指示與的通信狀態(tài)PROFIBUS主機(jī)。當(dāng)SYS LED呈紅色穩(wěn)定亮起時，PROFIBUS主控不再顯示正在掃描，當(dāng)它呈綠色時，PROFIBUS主控器正在成功掃描模塊作為運(yùn)行模式下的從機(jī)。琥珀色SYS LED指示PROFIBUS主機(jī)正在掃描在清除模式下，模塊作為從屬模塊。
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.
