SAIA PCD3.M5440 I/O总线仅将中央模块插入子机架即可建立与I/O模块的连接。无需进一步步骤。中央模块SAIA PCD3.M5440 PES H41q-H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中的数据存储器-连接I/O总线的多路复用器，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.M5440 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.M5440
The I/O Bus Just plugging-in the central module into the subrack establishes connection to the I/O modules. No further steps are required.Central ModuleSAIA PCD3.M5440 The central module of the PES H41q-H 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 SAIA PCD3.M5440 – 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.M5440
