如果5 V直流系统电源出现故障，中央模块上的硬件时钟和sRAM将由锂电池缓冲，锂电池也位于中央模块上。3.3.6将中央模块插入子机架中央模块SAIA PCD3.W310的I/O总线。PES H41q HR的中央模块包含中央模块结构中演示的基本功能：微处理器-操作系统和用户程序的程序存储器的闪存EPROM，可用于至少100.000个写入周期-sRAM多路复用器中的数据存储器连接I/O总线、DPR和冗余CU–双端口RAM，用于快速访问第二个中央模块–2个带电流隔离的RS 485接口。SAIA PCD3.W310传输速率：最大57600 bps。通过开关设置为9600 bps和57600 bps，或通过软件设置其他传输速率（软件值具有优先级）–诊断显示和2个LED，用于系统外信息、I/O级别和用户程序–电源监控–用于连接到输入/输出模块的I/O总线逻辑–硬件时钟，电池备份–故障保护看门狗–通过带监控的电池备份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
