REXROTH DDS02.1-W050-D螺紋端子用于連接電源和外部電池。24 V直流電源為CEX總線上的所有單元供電。光學(xué)模塊集群獨(dú)立供電。冗余鏈路由兩條電纜組成；RCU數(shù)據(jù)鏈路電纜和RCU控制鏈路電纜（見圖9）。圖11顯示了REXROTH DDS02.1-W050-D的框圖。處理器單元冗余可用于REXROTH DDS02.1-W050-D。在這種情況下，控制器包含兩個處理器單元，每個處理器單元包括用于系統(tǒng)和應(yīng)用軟件的存儲器。一個單元充當(dāng)主單元，另一個單元作為備用單元（熱備用）。主處理器單元控制該過程。備份服務(wù)器隨時待命，準(zhǔn)備在主服務(wù)器出現(xiàn)故障時接管。轉(zhuǎn)換在不到10毫秒的時間內(nèi)無擾動完成。在轉(zhuǎn)換過程中，過程輸出被凍結(jié)。轉(zhuǎn)換后，系統(tǒng)作為一個沒有冗余的系統(tǒng)運(yùn)行，只有一個處理器單元在運(yùn)行。您可以在系統(tǒng)運(yùn)行時更換出現(xiàn)故障的處理器單元。更換完成后，系統(tǒng)再次具有冗余處理器單元。REXROTH DDS02.1-W050-D
Screw terminals are provided for connections to the power supply and the external battery. The 24 V DC power supply powers all the units on the CEX-Bus. The optical module clusters are powered independently The Redundancy Link consists of two cables; RCU Data Link Cable and RCU Control Link Cable (see Figure 9). Figure 11 shows the block diagram of PM891.Processor unit redundancy is available for REXROTH DDS02.1-W050-D. In this case, the controller contains two processor units, each including memory for system and application software. One unit is acting as primary, the other is backup (hot stand-by). The primary processor unit controls the process. The backup stands by, ready to take over in case of a fault in the primary. The changeover is done bumplessly and in less than 10 ms. During the changeover, the process outputs are frozen. Following a changeover, the system operates as a system without redundancy with only one processor unit in operation. You can replace the malfunctioning processor unit while the system is running. After the replacement is carried out, the system once again has a redundant processor unit.REXROTH DDS02.1-W050-D
