說明HITACHI LPA210A/TP851用于連接到遠程I/O。通過PROFIBUS DP上的外部網(wǎng)關(guān)，現(xiàn)場儀表（PROFIBUS DP上）可以連接到AC 800M。TP851基板有一個內(nèi)螺紋DB9連接器，用于連接PROFIBUS DP。底板有一個代碼鎖，見第75頁表4，可防止在TP851底板上安裝不正確類型的裝置。HITACHI LPA210A擴展單元包含CEX總線邏輯、通信單元和DC/DC轉(zhuǎn)換器，該轉(zhuǎn)換器通過CEX總線從+24 V電源提供適當(dāng)?shù)碾妷?。PROFIBUS DP必須始終端接在兩個外部節(jié)點。ABB建議使用帶有內(nèi)置端接的連接器，因為即使現(xiàn)場總線與裝置完全斷開，也會始終端接。功能框圖圖69。方框圖–HITACHI LPA210A HITACHI LPA210A已被CI854通信接口所取代。HITACHI LPA210A僅因遺留原因而被描述。檢測到F（故障）/紅色單元錯誤。由控制軟件控制。在控制器重置期間由硬件設(shè)置并清除。R（un）/綠色運行。由控制軟件控制。在控制器重置過程中被硬件清除。Rx/Tx/黃色傳輸?shù)窖b置或從裝置傳輸。RTS/黃色請求從裝置發(fā)送。

escription HITACHI LPA210A / TP851 is used for connecting to remote I/O. Via an external gateway on PROFIBUS DP, field instruments (on PROFIBUS DP) can be connected to AC 800M. The TP851 Baseplate has one female DB9 connector for connecting PROFIBUS DP. The baseplate has a code lock, see Table 4 on page 75, that prevents the installation of an incorrect type of unit onto the TP851 Baseplate. The CHITACHI LPA210Aexpansion unit contains the CEX-Bus logic, a communication unit and a DC/DC converter that supplies appropriate voltages from the +24 V supply, via the CEX-Bus. The PROFIBUS DP must always be terminated at the two outer nodes.ABB recommends the use of connectors with built-in termination since the fieldbus will always be terminated even if fully disconnected from the unit.
