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.
