2.產(chǎn) 品 詳 情 資 料：
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(xiàn)上的所有單元供電。光學(xué)模塊集群獨立供電。冗余鏈路由兩條電纜組成；RCU數據鏈路電纜和RCU控制鏈路電纜（見(jiàn)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(gè)處理器單元，每個(gè)處理器單元包括用于系統和應用軟件的存儲器。一個(gè)單元充當主單元，另一個(gè)單元作為備用單元（熱備用）。主處理器單元控制該過(guò)程。備份服務(wù)器隨時(shí)待命，準備在主服務(wù)器出現故障時(shí)接管。轉換在不到10毫秒的時(shí)間內無(wú)擾動(dòng)完成。在轉換過(guò)程中，過(guò)程輸出被凍結。轉換后，系統作為一個(gè)沒(méi)有冗余的系統運行，只有一個(gè)處理器單元在運行。您可以在系統運行時(shí)更換出現故障的處理器單元。更換完成后，系統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
