检测到F（故障）/红色单元错误。由控制软件控制。在控制器重置期间由硬件设置并清除。R（un）/绿色运行。由控制软件控制。在控制器重置过程中被硬件清除。ACCESS EN（启用）/黄色访问启用开关激活。DEGR（加载）模式/黄色保留以备将来使用。PRIM/黄色表示该装置用作主SM810。SYNC（已同步）/黄色表示SM810已同步。SM810同步期间闪烁。内存•4 MB闪存PROM（固件存储）。•32 MB的SDRAM。电流隔离是的连接器一个7针螺丝连接器电流消耗（来自CEX总线24 V DC）160 mA典型（最大250 mA）功耗3.8 W典型关键功能•MPC862P微处理器在96 MHz下运行。•32 MB RAM•在SIL1-2操作期间提供对PM865控制器的监督，并与PM865一起形成用于SIL3应用的1oo2多样架构。•过电压保护。•内部电压监测。•支持热插拔。•支持冗余。•用于冗余对同步的SM链路。物理描述SM811装置由两部分组成：端接板（TP868）和SM811。SM811包含两个pc板。主板包含MPC862、SDRAM、闪存PROM和CEX总线从接口。子板包含数字I/O，+3.3V电源，带过电压保护和电压监测。端接板包含CEX总线连接器和数字I/O连接器。
F(ault) /Red Unit error detected. Controlled by Control Software. Set and cleared by the Hardware during controller Reset. R(un) /Green Operational. Controlled by the Control Software. Cleared by the Hardware during controller Reset. ACCESS EN(abled) /Yellow Access Enable switch active. DEGR(aded) MODE /Yellow Reserved for future use. PRIM /Yellow Indicates that the unit is used as the primary SM810. SYNC(hronized) /Yellow Indicates that the SM810 is synchronized. Flashes during SM810 synchronization.Memory • 4 MB flash PROM (firmware storage). • 32 MB of SDRAM. Galvanic isolation Yes Connector One 7 pin screw connector Current consumption (from CEX-Bus 24 V DC) 160 mA typical (250 mA max) Power dissipation 3.8 W typica Key Features • MPC862P Microprocessor running at 96 MHz. • 32 MB RAM • Provides supervision of the PM865 controller during SIL1-2 operations and together with the PM865 forms a 1oo2 diverse architecture for SIL3 applications. • Over voltage protection. • Internal voltage monitoring. • Supports hot swap. • Supports redundancy. • SM Link for synchronization of redundant pair. Description Physically SM811 Unit consists of two parts: Termination Plate (TP868) and SM811. The SM811 contains two pc-boards. The main board contains the MPC862, SDRAM, Flash PROM, and CEX-Bus slave interface. A daughter board contains digital I/O, +3.3V supply with over-voltage protection and voltage monitoring. The termination plate contains CEX-Bus connectors and connectors for the digital I/O.
