For the Functional Block Diagram, see Figure 4 on page 39 and

Figure 5 on page 40. 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.
