HIMA H51q-HRS B5233-2控制器
1.產(chǎn) 品 詳 情 資 料：
HIMA H51q-HRS B5233-2擴(kuò)展單元包含CEX總線邏輯、帶存儲器的CPU內(nèi)核、帶線路冗余單元的PROFIBUS接口和DC/DC轉(zhuǎn)換器，該轉(zhuǎn)換器通過CEXBus從+24V電源提供適當(dāng)?shù)碾妷骸ROFIBUS DP必須始終在兩個外部節(jié)點(diǎn)處終止。這通常是通過使用帶有內(nèi)置終端的連接器來完成的。為了保證正確的工作終端，必須插入連接器并提供電源。必須滿足屏蔽/接地的PROFIBUS DP要求。PROFIBUS DP安裝指南要求電纜屏蔽應(yīng)在電纜兩端接地。盡管CI854/CI854A已經(jīng)通過檢測到的連接器F（故障）/紅色單元錯誤將屏蔽連接到地，但必須這樣做。在控制器重置期間由硬件設(shè)置。復(fù)位后由控制軟件控制。R（un）/綠色運(yùn)行。在控制器重置過程中被硬件清除。復(fù)位后由控制軟件控制。線路A上的RxA/黃色接收數(shù)據(jù)。對于收到的每一封電報，LED都會閃爍。在正常操作中，視為靜態(tài)打開。RxB/線路B上的黃色接收數(shù)據(jù)。對于收到的每一封電報，LED都會閃爍。在正常操作中被視為靜態(tài)亮起。PRIM（ary）/黃色（CI854A）此LED在單個和冗余配置中亮起。表示主CI854A處于冗余配置。DUAL/黃色（CI854A）當(dāng)CI854A在冗余配置中運(yùn)行時，此指示燈亮起
The HIMA H51q-HRS B5233-2 expansion unit contains the CEX-Bus logic, the CPU-kernel with memory, the PROFIBUS interface with line redundancy unit and a DC/DC converter that supplies the appropriate voltages from the +24V supply, via the CEXBus. The PROFIBUS DP must always be terminated at the two outer nodes. This is usually done by using connectors with built-in termination. To guarantee a correct working termination the connector has to be plugged and power supplied. The PROFIBUS DP requirements for screening/earthing have to be fulfilled. The PROFIBUS DP installation guideline requires that the cable shield should be connected to ground at both ends of the cable. This has to be done although the CI854/CI854A already connects the shield to ground via the connectors F(ault) /Red Unit error detected. Set by the Hardware during controller Reset. Controlled by the Control Software after Reset. R(un) /Green Operating. Cleared by the Hardware during controller Reset. Controlled by the Control Software after Reset. RxA /Yellow Receive Data on Line A. For each telegram received the LED flashes. In normal operation is seen as static on. RxB /Yellow Receive Data on Line B. For each telegram received the LED flashes. In normal operation is seen as static on. PRIM(ary) /Yellow (CI854A) This LED is on in single and redundant configuration. Indicates Primary CI854A in redundant configuration. DUAL /Yellow (CI854A) This LED is on when CI854A is running in redundant configuration
