如果5 V直流系統(tǒng)電源出現(xiàn)故障，中央模塊上的硬件時(shí)鐘和sRAM將由鋰電池緩沖，鋰電池也位于中央模塊上。3.3.6將中央模塊插入子機(jī)架中央模塊SAIA PCD3.W310的I/O總線。PES H41q HR的中央模塊包含中央模塊結(jié)構(gòu)中演示的基本功能：微處理器-操作系統(tǒng)和用戶(hù)程序的程序存儲(chǔ)器的閃存EPROM，可用于至少100.000個(gè)寫(xiě)入周期-sRAM多路復(fù)用器中的數(shù)據(jù)存儲(chǔ)器連接I/O總線、DPR和冗余CU–雙端口RAM，用于快速訪問(wèn)第二個(gè)中央模塊–2個(gè)帶電流隔離的RS 485接口。SAIA PCD3.W310傳輸速率：最大57600 bps。通過(guò)開(kāi)關(guān)設(shè)置為9600 bps和57600 bps，或通過(guò)軟件設(shè)置其他傳輸速率（軟件值具有優(yōu)先級(jí)）–診斷顯示和2個(gè)LED，用于系統(tǒng)外信息、I/O級(jí)別和用戶(hù)程序–電源監(jiān)控–用于連接到輸入/輸出模塊的I/O總線邏輯–硬件時(shí)鐘，電池備份–故障保護(hù)看門(mén)狗–通過(guò)帶監(jiān)控的電池備份sRAM。SAIA PCD3.W310
SAIA PCD3.W310In case the 5 V DC system power fails hardware clock and sRAM on the central module are buffered by a lithium battery which is also on the central module. 3.3.6 The I/O Bus Just plugging-in the central modules into the subrack Central Module SAIA PCD3.W310The central module of the PES H41q-HR contains the essential functions demonstrated in the structure of the central module: – Microprocessor – Flash-EPROMs of the program memory for the operating system and the user's program usable for min. 100.000 writing cycles – Data memory in sRAM Multiplexer to connect I/O bus, DPR and redundant CU – Dual Port RAM for fast memory access to the second central module – 2 interfaces RS 485 with galvanic isolation. Transmission rate: max. 57600 bps. Set to 9600 bps and to 57600 bps by switch, or setting also of other transmission rates by software (the software values have priority) – Diagnostic display and 2 LEDs for information out of the system, I/O level and user's program – Power supply monitoring – I/O-Bus logic for the connection to the input/output modules – Hardware clock, battery backed – Fail-safe watchdog – Battery backup of the sRAMs via batteries with monitoring.SAIA PCD3.W310
