In the AC 800M High Integrity Controller, it is possible to run both non-SIL and SIL classified applications. The AC 800M HI consist of PM865, SM810/SM811 and a High Integrity version of Control Software, and is also available in redundant configuration. AC 800M HI requires the use of SIL certified S800 I/O units in SIL classified applications. If the application is not SIL classified, standard S800 I/O units can be used with AC 800M HI controller. Figure 1 shows the physical appearance of an AC 800M Controller with an S800 I/O Unit. This physical appearance does not apply to PM891.  Physically the PM8xx/TP830 Processor Unit consists of two basic parts: • Processor Unit (PM851/PM851A/PM856/PM856A/PM860/PM860A/PM861/PM861A/ PM864/PM864A/PM865/PM866) with processor and Power Supply boards. • Baseplate (TP830), housing the unit termination board. For the Functional Block Diagram, see Figure 4 on page 35 and Figure 5 on page 36. The CPU board contains the microprocessor and the RAMmemory, controllers for all built-in communication interfaces, real-time clock, LED indicators, INIT push button and a Compact Flash interface. The main function of the power supply board is to generate isolated, circuit-proof +5 V and +3.3 V supplies to the CPU and I/O units. The board also contains optoisolated RS-232C drivers/receivers for the service port, together with a back-up battery holder for memory/real time clock, (RTC). The termination board, housed in the TP830 Baseplate, is where the majority of the external connections terminates. The board is grounded to the DIN-rail through of the metallic components of the housing. The termination board is provided with screw terminals for power supply and redundant power supply monitoring, with RJ45 connectors for the control network and serial port, a connector for the service port, the electrical ModuleBus and the CEX-Bus. The 24 V DC supply, connected to the TP830 Baseplate, powers all the units on the CEX-Bus and the electrical ModuleBus. In single CPU configuration, it is possible to connect an S800 I/O cluster directly to the built-in electrical ModuleBus plug located on the right hand side of the TP830 Baseplate. The processor unit has a communication expansion bus connector located on the left-hand side of the TP830 Baseplate. This CEX-Bus provides for extending the on-board communication ports with additional communication interfaces.
